#Monthly Distribution Consistency 
#QA flags which describe how consistent a monthly distribution is with other distributions for the same month, across the years.  
#This is done by calculating how consistent a monthly distribution of measurements is with the distributions for the same month of the neighbouring 5 years (backwards and forwards in time), as well as calculating how this metric of consistency differs from all other calculated metrics for the same month, across the time series.
#Kernel density estimation (kde) is used to estimate the probability density function (PDF) for the month in question, as well as the neighbouring year months.  
#The intersection is then taken between the month in question's PDF and the surrounding months PDF's, for which 1.0 - the median intersection value is taken as the metric of consistency (perfect intersection = 0.0, no intersection = 1.0). 
#Only the neighbouring 5 years are used, to limit the impact of any long-term trends biasing the comparison. 
#Additionally determined is to what extent does the median PDF intersection metric per month differ from the typical (median) intersection score for the same month across the entire timerseries (0.0 = perfectly consistent or better than the median intersection score, 1.0 = intersection score is as far below as possible the median intersection score). 
#This metric provides a weighting for the multi-annual variance of the monthly distributions. If there is a low intersection score, but there are typically always low intersection scores due to high variance across the years, then the difference score will be close to 0.0. Conversely, if there is a low intersection score, but there are typically always high intersection scores, then the difference score will be closer to 1.0, as it is outlying.           
#These metrics are then both summed to give a total classification score of the normality of the monthly distribution (2.0 = Extremely different from typical case. 0.0 = Extremely consistent with typical case).
#The classification score is split into 10 zones (in range increments of 0.2) from the most consistent monthly distributions in Zone 1 (score of 0.0 to 0.2), to the least consistent monthly distributions in Zone 10 (score of 1.8 to 2.0).
#All months for which a total classification score can be determined are flagged with a flag for the respective classification score zone.
#If 2/3, 4/6, 8/12 consecutive months are classed as zone 6 or higher, then it is suspected there is a systematic reason for the non-typical distributions, and the entire periods are flagged.

#------------------------------------
#low volume continuous/high volume continuous

#Ambient air is continuously drawn in by a pump of some description. 

#The rate that air is sampled can be particularly important for the measurements of particulate matter.
#Many particulate matter measurements utilise a 2-step process, where standalone samplers first sample and filter air, and then the filtered products are measured by separate instrument.
#The standalone samplers can be separated into 2 discrete groups: low volume samplers & high volume samplers.

#Many instruments also have built-in continuous samplers. These are in-almost all cases low-volume, when not otherwise stated.

#--------
#low volume continuous

#Ambient air is continuously drawn in using a low volume sampler (typically sampling < ~24,000 litres of air over a 24-hour period)
#Some of these samplers have in-built filters, designed to specifically retain certain compounds.

#diffusive sampler

#Diffussive samplers are a specific utilisation of sorbent trapping to passively trap species over long time periods, typically in urban areas.
#Diffusive samplers are an inexpensive method for measuring atmospheric composition over periods from one day to several weeks.
#These samplers operate on the principle of a sorbent trapping and retaining a compound of interest. 
#Sorption often takes place through reaction with a reagent (i.e. typically TEA for NO2).  
#After a suitable sample time, the trapped compound can then be analysed using colorimetry/spectrophotometry/ion chromatography/GC methods 

#Diffusive samplers come in various forms, e.g: Palmes, Passam, Ogawa Badge, and Radiello radial sampler tubes.
#The way these tubes differ is associated with the way they sample air and deal with variations in meteorological conditions. 

#This method is typically associated with very large uncertainties. 
#These uncertainties mainly come from:
#1. The non-specificity of trapped gases (i.e. HONO and PAN are readily uptaken when attempting to trap NO2).
#2. Variability in temperature, relative humidity, and air velocity directly impacting upon uptake rate of the desired gas, and effectiveness of the sorbent.
#Uncertainties associated with this methodology are typically reported between 10-35%: http://publications.jrc.ec.europa.eu/repository/bitstream/JRC51106/reqno_jrc51106_eur_23793.pdf[1].pdf

#Unless additional information is given, make assumption all diffusive samplers trap gases through sorbent trapping, followed by subsequent analysis through ion chromatography (by injection).

#------
#detection tube
    
#Gas detection tubes operate on a chemical reaction between the vapour-phase compound and a liquid or solid detecting reagent, which is supported on an inert matrix. 
#The most common types of reactions are:
#   -Acid-base reactions These include reactions of acidic gases like HCl and HF with bases, and reaction of alkaline vapors such as ammonia with an acid in the tube. A dye present in the tube changes color as the pH changes on exposure to the vapors.
#   -Reduction-oxidation (Red-ox) reactions: These generate an oxidized or reduced compound, which has a different color. The chlorine tube uses oxidative coupling of colorless o-toluidine to form an orange azo-dye. White di-iodine pentoxide is reduced by CO and many organic vapors to form deep brown-colored iodine. Orange chromium (VI) is reduced by many organic compounds to form brown or green-colored Cr(III) compounds.
#   -Ligand-exchange reactions: These generate new complexes that are more colored than the starting reagents. The most notable is the conversion of white lead acetate to brown-black lead sulfide in the detection of H2S. In the case of phosphine, the exchange of PH3 for the chlorine ligand of HgCl2 releases HCl, which then causes a pH- dependent dye-color change.
#   -Pre-layers or Pre-tubes: These are used to condition the sample by controlling humidity, removing interferences, or transforming the analyte to another detectable compound. Examples include drying agents in NH3 and HCl tubes, organic removal by charcoal or oxidation in selective CO tubes, and oxidation of NO to NO2 in the nitrogen oxides tube.

#Most detection tubes are length-of-stain types. In these tubes, the reaction of the gas with the supported reagent is fast, compared to the transport of the bulk air sample through the tube. Therefore, all of the detected vapors are reacted within the tube. As a result, there is not a strong dependence of the readings on the rate at which the gas is sampled. However, a very high flow rate can cause some smearing to a high reading. 
#Conversely, low flow rates are less likely to affect the stain length, but can give low readings by concentrating the colored products in a shorter section of the tube. In cases of flow extremes, errors outside the standard 25% accuracy can be produced.
#Detection tubes are usually calibrated using piston hand pumps. The flow during a single pump stroke initially rises sharply and then decays exponentially. The best accuracy is therefore obtained when the flow through the tube mimics this profile.
#The advantages of detection tubes over other analytical methods are simplicity of use, rapid response, low cost, and very low maintenance. Because tubes are typically pre-calibrated, no calibration equipment is necessary. 
#Errors are prevented by directly marking the calibration information on each tube, and accuracy is further ensured by controlling the volume of air sampled. 
#Air sampling can also be performed using piston pumps, which latch into a precisely defined position to fix the volume. These pumps pull a strong vacuum initially and thus create substantially higher flowrate than the bellows pumps. Piston pumps generate a high flow initially followed by an approximately exponential decay, whereas bellows pumps provide a more steady flow initially followed by the slow decay. 
#The difference in flow patterns means that the pumps cannot be interchanged between types. For example, piston pumps sometime cause a smearing of the color stain when used on tubes originally developed for bellows pumps. This occurs because the higher flow rates do not allow enough contact time to give sharp endpoints when a piston pump is used.   

#Uncertainty on measurements is typically high with this method, typically reported between 10-25 %: https://www.honeywellanalytics.com/~/media/honeywell-analytics/products/colorimetric-gas-detection-tubes/documents/hagastubeshandbook667802enlr.pdf?la=en

#Unless additional information is given, make assumption all detection tubes trap and produce characteristic colour through reagent reaction, followed by subsequent analysis through colorimetry (manual).

#ultraviolet photometry

#Operates on the principle that a specific species efficiently absorbs light at a known wavelength in the UV range. This is the case for ozone, at 253.65nm.
#The degree to which the UV light is absorbed by a specific species is directly related to the species concentration as described by tha (I/Io = e−KLC; K = molecular absorption coefficient at STP (308 cm-1 atm-1 for O3), L = optical path length of cell, C = species concentration , I = light intensity of sample gas, Io = light intensity of sample without measured species (reference gas) ).

#Typical measurement operation for ozone:
#1. Ambient air is continuously drawn through the analyser by a vacuum pump. 
#2. Sample is split into two flow paths. One path incorporates a scrubber which selectively removes ozone, while the other path does not. 
#3. Both flow paths are connected to a solenoid valve, which switches at a fixed interval to allow either the sample gas stream (I), or the scrubbed, reference gas stream (Io), to flow through a quartz tube (cell) of accurately known length. 
#4. Typically a mercury vapour lamp at one end of the quartz cell produces a monochromatic beam of ultraviolet light at 254 nm. A vacuum diode at the opposite end of the cell measures the intensity of transmitted light (I/Io). 
#5. The intensities of 254 nm UV light transmitted through the sample (I) and ozone-free reference gas streams (Io) are related to the concentration (C) of ozone in the sample gas stream according to the Beer-Lambert Law.
#6. The analyzer’s microprocessor calculates the absolute concentration in molecules cm-3, and is then converted to a mixing ratio using in-instrument measured sample temperature and pressure.

#Known interferences: Gaseous hydrocarbons with strong absorption at 254 nm, such as aromatic hydrocarbons (i.e., benzene and substituted benzene rings).

#The greatest source of uncertainty regarding this measurement type is the cross sectional value used, for which the conventional value has been called into question: see further details: https://www.bipm.org/en/bipm/chemistry/gas-metrology/ozone/ozone-cross-section.html

#visible photometry

#Operates on the principle that a specific species efficiently absorbs light at a known wavelength in the visible range. This is the case for NO2, at 405nm
#The degree to which the visible light is absorbed by a specific species is directly related to the species concentration as described by the Beer-Lambert Law (C = 1/Lσ * ln(Io/I) ; σ = absorption cross section (6.06×10-19 cm2 molec-1 for NO2 at 405nm), L = optical path length of cell, C = species concentration , I = light intensity of sample gas, Io = light intensity of sample without measured species (reference gas) ).

#Typical measurement operation for NO2 (and indirectly NO):
#1. Ambient air is continuously drawn through the instrument by a vacuum pump. 
#2. An NO2 scrubber valve alternately bypasses and sends the sample air through a heated NO2 scrubber to remove all NO2 in the sample. 
#3. The NO2-scrubbed/unscrubbed air alternately passes through the optical cell (of known length) and the cell flow meter. Alternate switching of the NO2 scrubber valve once every 5 seconds allows the measurement of a light intensity in the absence of NO2 and presence of NO2. 
#4. A light-emitting diode (LED) emits a monochromatic beam of light at 405nm. A photodiode at the other end of the cell measures the intensity of transmitted light (I/Io).
#5. The intensities of 405 nm light transmitted through the sample (I) and NO2-free reference gas streams (Io) are related to the concentration (C) of ozone in the sample gas stream according to the Beer-Lambert Law.
#6. The analyser's microprocessor calculates the absolute concentration in molecules cm-3, and is then converted to a mixing ratio using in-instrument measured sample temperature and pressure.
#7. NO is measured indirectly by bypassing the NO2 scrubber and measuring the light intensity while adding (I) or not adding (Io) ozone to convert NO to NO2 according to the well-known reaction: NO + O3 → NO2 + O2

#chemiluminescence (internal molybdenum converter)

#Chemiluminescence is the emission of light (luminescence), as the result of a chemical reaction. Chemiluminescence occurs as a result of the reaction of NO with ozone (NO+O3 --> NO2*+O2).
#The return to a fundamental electronic state of the excited NO2* molecules is made by luminous radiation in a 600-3000 nm spectrum (NO2* --> NO2 + hv), which can be measured.
#This method is designed specifically to directly measure NO directly (and NOx/NO2 indirectly). O3 can also be measured by inverting the measurement technique (using canister of NO for reaction).

#Typical measurement operation for NO (and NOx/NO2 indirectly):
#1. Sample air is drawn into the reaction cell via two separate (alternating) paths; the NO and NOx channels.
#2. NO in the first path (NO channel) reacts with ozone (from ozone generator) according to the following reaction: NO+O3 --> NO2*+O2.
#3. The excited NO2 molecules quickly returns to the ground state, releasing the excess energy. This release takes the form of a quantum of light (hv). The distribution of wavelengths for these quanta range between 600 and 3000 nm, with a peak at about 1200 nm (NO2* --> NO2 +hv (1200nm))
#4. Luminescence from the reaction is detected using a photomultiplier tube (PMT). Photons enter the PMT and strike a negatively charged photo cathode causing it to emit electrons. These electrons are accelerated by an applied high voltage and multiplied through a sequence of similar acceleration steps (dynodes) until a useable current signal is generated. The more light present (in this case photons given off by the chemiluminescent reaction described above), the more current is produced. Therefore the more NO present in the reaction cell the more current is produced by the PMT.
#5. Before entering the PMT, light is passed through a high-pass optical filter only transparent to wavelengths of light above 645nm. The narrowness of this band of sensitivity allows avoids the potential of extraneous light and radiation that might interfere with the measurement (e.g. some oxides of sulfur can also be chemiluminescent emitters when in contact with O3 but give off light at much shorter wavelengths (usually around 260nm to 480nm)).
#6. All things being constant (temperature, pressure, amount of ozone present, etc.), the relationship between the amount of NO present in the reaction cell and the amount of light emitted from the reaction is very linear. If more NO is present, more IR light is produced. 
#7. In addition, sometimes the excited NO2 collides with other gaseous molecules in the reaction cell chamber or even the molecules of the reaction cell walls and transfers its excess energy to this collision partner (represented by M) without emitting any light at all. In fact, by far the largest portion of the excited NO2 returns to the ground state this way, leaving only a few percent yield of usable chemiluminescence (NO2* + M --> NO2 + M). The probability of a collision between the NO2* molecule and a collision partner M increases proportionally with the reaction cell pressure. This non-radiating collision with the NO2* molecules is usually referred to as third body quenching. Even under the best conditions only about 20% of the NO2 that is formed by the key chemiluminescence reaction is in the excited state. In order to maximize chemiluminescence, the reaction cell is maintained at reduced pressure (thereby reducing the amount of available collision partners) and is supplied with a large, constant excess of ozone (about 3000-5000 ppm) from the internal ozone generator.
#8. The second path (NOx channel) travels through a delay loop and a heated molybdenum converter (at 315degC). The heated molybdenum reacts with NO2 in the sample gas and produces a NO gas and a variety of molybdenum. (xNO2 + yMo --> xNO + MyOz (at 315degC)).
#9. Once the NO2 in the sample gas has been converted to NO, it is routed to the reaction cell where it undergoes the chemiluminescence reaction and is measured by the PMT.
#10. By converting the NO2 in the sample gas into NO, the analyser indirectly measures total NOx content of the sample gas (i.e. the NO present + the converted NO2 present). 
#11. By switching the sample gas stream in and out of the molybdenum converter every 6 - 10 seconds, the analyser is able to quasi-continuously measure both the NO and the total NOx content.
#12. The NO2 concentration is not directly measured but calculated by subtracting the known NO content of the sample gas from the known NOx content.

#Known interferences: Water vapour (above 20 ppmv), 3rd body quenching (CO2, SOx), other NOy species converted to NO by molybdenum converter (PAN, ethyl nitrate, ethyl nitrite, HONO, HNO3, methyl nitrate, n-propyl nitrate, n-butyl nitrate, nitrocresol, NH3), other species undergoing chemiluminescence with O3 (SOx).

#Not QA accepted measurement technique for NO2/NOx due to bias in measuring NO2, due to molybdenum converters.

#chemiluminescence (external molybdenum converter)

#Chemiluminescence is the emission of light (luminescence), as the result of a chemical reaction. Chemiluminescence occurs as a result of the reaction of NO with ozone (NO+O3 --> NO2*+O2).
#The return to a fundamental electronic state of the excited NO2* molecules is made by luminous radiation in a 600-3000 nm spectrum (NO2* --> NO2 + hv), which can be measured.
#This method is designed specifically to directly measure NO (and NOy indirectly).

#Typical measurement operation for NO (and NOy indirectly)
#1. Sample air is drawn into the reaction cell via two separate (alternating) paths; the NO and NOy channels.
#2. NO in the first path (NO channel) reacts with ozone (from ozone generator) according to the following reaction: NO+O3 --> NO2*+O2.
#3. The excited NO2 molecules quickly returns to the ground state, releasing the excess energy. This release takes the form of a quantum of light (hv). The distribution of wavelengths for these quanta range between 600 and 3000 nm, with a peak at about 1200 nm (NO2* --> NO2 +hv (1200nm))
#4. Luminescence from the reaction is detected using a photomultiplier tube (PMT). Photons enter the PMT and strike a negatively charged photo cathode causing it to emit electrons. These electrons are accelerated by an applied high voltage and multiplied through a sequence of similar acceleration steps (dynodes) until a useable current signal is generated. The more light present (in this case photons given off by the chemiluminescent reaction described above), the more current is produced. Therefore the more NO present in the reaction cell the more current is produced by the PMT.
#5. Before entering the PMT, light is passed through a high-pass optical filter only transparent to wavelengths of light above 645nm. The narrowness of this band of sensitivity allows avoids the potential of extraneous light and radiation that might interfere with the measurement (e.g. some oxides of sulfur can also be chemiluminescent emitters when in contact with O3 but give off light at much shorter wavelengths (usually around 260nm to 480nm)).
#6. All things being constant (temperature, pressure, amount of ozone present, etc.), the relationship between the amount of NO present in the reaction cell and the amount of light emitted from the reaction is very linear. If more NO is present, more IR light is produced. 
#7. In addition, sometimes the excited NO2 collides with other gaseous molecules in the reaction cell chamber or even the molecules of the reaction cell walls and transfers its excess energy to this collision partner (represented by M) without emitting any light at all. In fact, by far the largest portion of the excited NO2 returns to the ground state this way, leaving only a few percent yield of usable chemiluminescence (NO2* + M --> NO2 + M). The probability of a collision between the NO2* molecule and a collision partner M increases proportionally with the reaction cell pressure. This non-radiating collision with the NO2* molecules is usually referred to as third body quenching. Even under the best conditions only about 20% of the NO2 that is formed by the key chemiluminescence reaction is in the excited state. In order to maximize chemiluminescence, the reaction cell is maintained at reduced pressure (thereby reducing the amount of available collision partners) and is supplied with a large, constant excess of ozone (about 3000-5000 ppm) from the internal ozone generator.
#8. The second path (NOy channel) before entering the instrument enters an externally mounted heated molybdenum converter (at 315degC), with less than 10cm tubing between the converter and sample entry. The heated molybdenum reacts with NOy in the sample gas and produces a NO gas and a variety of molybdenum (3NOy + Mo --> 3NO + MoO3 (at 315degC)). Minimising the transit time and surface contact area between the sample inlet and converter enables the conversion of labile components of NOy.
#9. Once the NOy in the sample gas has been converted to NO, it is routed to the reaction cell where it undergoes the chemiluminescence reaction and is measured by the PMT.
#10. By converting the NOy in the sample gas into NO, the analyser indirectly measures total NOy content of the sample gas (i.e. the NO present + the converted NO2 present). 
#11. By switching the sample gas stream in and out of the molybdenum converter every 6 - 10 seconds, the analyser is able to quasi-continuously measure both the NO and the total NOy content.

#Known interferences: Water vapour (above 20 ppmv), 3rd body quenching (CO2, SOx), other species undergoing chemiluminescence with O3 (SOx).

#8. The second path (NOx channel) travels through a delay loop and a photolytic converter. As the sample gas passes through the converter chamber it is exposed to blue light at specific wavelengths (350-420 nm) from a photolytic light source (blue LEDs, metal halide). This selectively converts NO2 to NO with negligible radiant heating or interference from other gases (NO2 +hv (350-420nm) --> NO + O).
#9. Once the NO2 in the sample gas has been converted to NO, it is routed to the reaction cell where it undergoes the chemiluminescence reaction and is measured by the PMT.
#10. By converting the NO2 in the sample gas into NO, the analyser indirectly measures total NOx content of the sample gas (i.e. the NO present + the converted NO2 present). 
#11. By switching the sample gas stream in and out of the photolytic converter every 6 - 10 seconds, the analyser is able to quasi-continuously measure both the NO and the total NOx content.
#12. The NO2 concentration is not directly measured but calculated by subtracting the known NO content of the sample gas from the known NOx content.

#Known interferences: Water vapour (above 20 ppmv), 3rd body quenching (CO2, SOx), thermal decomposition of PAN to NO2 within the photolysis cell

#chemiluminescence (internal molybdenum and quartz converters) (CL(IMQC))

#Chemiluminescence is the emission of light (luminescence), as the result of a chemical reaction. Chemiluminescence occurs as a result of the reaction of NO with ozone (NO+O3 --> NO2*+O2).
#The return to a fundamental electronic state of the excited NO2* molecules is made by luminous radiation in a 600-3000 nm spectrum (NO2* --> NO2 + hv), which can be measured.
#This method is designed specifically to directly measure NO (and NH3/NOx/NO2 indirectly). 

#Typical measurement operation for NO (and NH3/NOx/NO2 indirectly)
#1. Sample air is drawn into the reaction cell via three separate (alternating) paths; the NO, TNx and NOx channels.
#2. NO in the first path (NO channel) reacts with ozone (from ozone generator) according to the following reaction: NO+O3 --> NO2*+O2.
#3. The excited NO2 molecules quickly returns to the ground state, releasing the excess energy. This release takes the form of a quantum of light (hv). The distribution of wavelengths for these quanta range between 600 and 3000 nm, with a peak at about 1200 nm (NO2* --> NO2 +hv (1200nm))
#4. Luminescence from the reaction is detected using a photomultiplier tube (PMT). Photons enter the PMT and strike a negatively charged photo cathode causing it to emit electrons. These electrons are accelerated by an applied high voltage and multiplied through a sequence of similar acceleration steps (dynodes) until a useable current signal is generated. The more light present (in this case photons given off by the chemiluminescent reaction described above), the more current is produced. Therefore the more NO present in the reaction cell the more current is produced by the PMT.
#5. Before entering the PMT, light is passed through a high-pass optical filter only transparent to wavelengths of light above 645nm. The narrowness of this band of sensitivity allows avoids the potential of extraneous light and radiation that might interfere with the measurement (e.g. some oxides of sulfur can also be chemiluminescent emitters when in contact with O3 but give off light at much shorter wavelengths (usually around 260nm to 480nm)).
#6. All things being constant (temperature, pressure, amount of ozone present, etc.), the relationship between the amount of NO present in the reaction cell and the amount of light emitted from the reaction is very linear. If more NO is present, more IR light is produced. 
#7. In addition, sometimes the excited NO2 collides with other gaseous molecules in the reaction cell chamber or even the molecules of the reaction cell walls and transfers its excess energy to this collision partner (represented by M) without emitting any light at all. In fact, by far the largest portion of the excited NO2 returns to the ground state this way, leaving only a few percent yield of usable chemiluminescence (NO2* + M --> NO2 + M). The probability of a collision between the NO2* molecule and a collision partner M increases proportionally with the reaction cell pressure. This non-radiating collision with the NO2* molecules is usually referred to as third body quenching. Even under the best conditions only about 20% of the NO2 that is formed by the key chemiluminescence reaction is in the excited state. In order to maximize chemiluminescence, the reaction cell is maintained at reduced pressure (thereby reducing the amount of available collision partners) and is supplied with a large, constant excess of ozone (about 3000-5000 ppm) from the internal ozone generator.
#8. In the second path (TNx channel), sample air is passed through an internal heated quartz converter (at 980 degC). The heated quartz reacts with NH3 and NO2 in the sample gas and produces a NO gas (4NH3 + 5O2 --> 4NO + 6H2O).
#9. Once the NO2 and NH3 in the sample gas has been converted to NO, it is routed to the reaction cell where it undergoes the chemiluminescence reaction and is measured by the PMT.
#10. By converting the NO2 and NH3 in the sample gas into NO, the analyser indirectly measures total TNx content of the sample gas. 
#11. The third path (NOx channel) travels through a delay loop and a heated molybdenum converter (at 315degC). The heated molybdenum reacts with NO2 in the sample gas and produces a NO gas and a variety of molybdenum. (xNO2 + yMo --> xNO + MyOz (at 315degC)).
#12. Once the NO2 in the sample gas has been converted to NO, it is routed to the reaction cell where it undergoes the chemiluminescence reaction and is measured by the PMT.
#13. By converting the NO2 in the sample gas into NO, the analyser measures total NOx content of the sample gas (i.e. the NO present + the converted NO2 present). 
#14. By switching the sample gas stream between the 3 streams frequently, the analyser is able to quasi-continuously measure both the NO, the total NOx content and TNx.
#15. NO2 is indirectly calculated by subtracting the known NO content of the sample gas from the known NOx content.
#16. NH3 is indirectly calculated by subtracting the known NOx content of the sample gas from the known TNx content.

#Known interferences: Water vapour (above 20 ppmv), 3rd body quenching (CO2, SOx), other NOy species converted to NO by molybdenum converter (PAN, ethyl nitrate, ethyl nitrite, HONO, HNO3, methyl nitrate, n-propyl nitrate, n-butyl nitrate, nitrocresol, NH3), other species undergoing chemiluminescence with O3 (SOx).

#Not QA accepted measurement technique for NO2/NOx due to bias in measuring NO2, due to molybdenum converters.

#gas chromatography - sulphur chemiluminescence (GC-SC)

#Chemiluminescence is the emission of light (luminescence), as the result of a chemical reaction. Chemiluminescence occurs as a result of the reaction of SO and ozone (SO+O3 --> SO2*+O2).
#The return to a fundamental electronic state of the excited SO2* molecules is made by luminous radiation in a specific spectrum (SO2* --> SO2 + hv), which can be measured (by a photomultiplier tube).
#The concentration of sample total sulphur is directly proportional to the intensity of light emitted.
#This method can be mixed with gas chromatography (GC) to allow to determination of specific sulphur compounds (i.e. SO2).
#The gas sample is passed through a GC column before being ultimately measured by the photomultiplier detector.

#Gas chromatography (GC) is a method used for separating and analysing compounds that can be vaporized without decomposition.
#A sample solution is injected into a instrument, entering a gas stream which transports the sample (mobile phase) into a separation tube known as the "column".
#The mobile phase is a carrier gas, usually an inert gas such as helium or an unreactive gas such as nitrogen. Helium remains the most commonly used carrier gas in about 90% of instruments although hydrogen is preferred for improved separations.
#The column consists of a microscopic layer of liquid or polymer on an inert solid support a microscopic layer of liquid or polymer on an inert solid support (stationary phase), inside a piece of glass or metal tubing, placed inside a piece of glass or metal tubing.
#Once inside the column, the gaseous compounds being analysed interact with the walls of the column coated with a stationary phase. This causes each compound to elute at a different time, known as the retention time of the compound. 
#The comparison of retention times is what gives GC its analytical usefulness.
#If greater separation of compounds is required, multiple distinct columns can be used for this purpose.

#flame photometric detection (FPD)

#Many elements give characteristic emission when burned in flame. Absorption of energy from the flame allows a ground state atom or molecule to reach an excited state. 
#The atom/molecule may return to the ground state through emission of light (luminescence), which can be subsequently measured (by a photomultiplier tube). This process is a chemiluminescent process (where luminescence occurs as the result of a chemical reaction).
#The concentration of the sample gas is directly proportional to the intensity of light emitted.
#This method has been applied for the measurement of sulphur and potassium containing species (i.e. SO2) and as a detector 
#For specific measurement of solely SO2, the sample gas must be scrubbed of other sulphur species prior to measurement, and the photomultiplier detector measures emission centred near 394nm.

#Known interferences: Other sulphur compounds

#flame ionisation detection (FID)

#This method is based on the principle of the generation of an electrical current that is proportional to the rate of ion formation, dependent on the concentrations of species in the sample gas.
#The method is typically the standard detection method for column separated hydrocarbons, however the method is also sensitive to almost all compounds, mostly combustible ones. 
#There are, however, a few compounds to which the method has very little, if any, sensitivity, including: O2, N2, SO2, NO, N2O, NO2, NH3, CO, CO2, and H2O.
#When used as a standalone method (without prior chromatography) it is non-specific for mixed gases in the sample.

#Typical measurement operation for hydrocarbons:
#1. The sample gas is introduced into a hydrogen flame inside the flame ionisation detector.
#2. Any hydrocarbons in the sample will produce ions when they are burnt. 
#3. Ions are detected using a metal collector which is biased with a high DC voltage. 
#4. The current across this collector is thus proportional to the rate of ionisation which in turn depends upon the concentration of hydrocarbons in the sample gas.

#selective combustion - flame ionisation detection (SC-FID)

#This method combines flame ionisation detection with selctive combustion to enable to measurement of specific hydrocarbons in a mixed gaseous sample.
#This is most commonly employed for the measurement of CH4, but can be done for other hydrocarbons also. 

#Typical measurement operation for hydrocarbons:
#1. The sample gas is split into 2 lines
#2. On the first line, the sample gas is introduced into a hydrogen flame inside the flame ionisation detector (reference measurement).
#2. Any hydrocarbons in the sample will produce ions when they are burnt. 
#3. Ions are detected using a metal collector which is biased with a high DC voltage. 
#4. The current across this collector is thus proportional to the rate of ionisation which in turn depends upon the concentration of hydrocarbons in the sample gas.
#5. On the second line, the sample gas is first passed though a selective catalytic combustion unit, leaving only a specific hydrocarbon in the sample (oxidising the others), for example CH4
#6. This is then measured using FID, and thus gives the concentration of the isolated hydrocarbon
#7. If the isolated hydrocarbon measured on the second line is CH4, then line1 - line2 will give the NMHC concentration

#conductimetry (CD)

#Involves the absorption of a specific gas species in deionized water, to produce an acid, which can be detected by a conductivity cell.
#Through the use of the deionized water reagent, measurements are susceptible to interferences from CO2, salt aerosols, acid mists and basic gases. 
#Addition of hydrogen peroxide to the deionized water minimises interference (through reduced solubility of CO2 within the water).
#This method been used extensively to measure SO2.

#second derivative spectrophotometry (SDS)

#Spectrophotometry is a method based on Beer-Lambert's law, where the absorption of light transmitted through the medium is directly proportional to the medium concentration.
#The main disadvantage and limitation of the spectrophotometry is its low selectivity. The measurement of absorbance is burden by interferences derived from others components of sample.
#Derivative spectrophotometry involves plotting the first, second or higher order derivatives of a spectrum with respect to wavelength. 
#Usually this is obtained by a microprocessor connected in series with a spectrophotometer, which computes the derivative with respect to time as the spectrum is scanned at constant speed.
#The "true" wavelength derivative is linearly related to the time derivative recorded, the magnitude of which is directly affected by scanning speed and spectral band width.
#The derivative process provides two general advantages: first, an effective enhancement of resolution, which can be useful to separate two or more components with overlapping spectra; second, a discrimination in favour of the sharpest features of a spectrum, used to eliminate interferences by broad band constituents. However, this process results in a decrease in the signal to noise ratio.
#Both advantages and disadvantages increase with the derivative order. Generally, the second derivative is more useful than the first ones.

#coulometry (CM)

#Coulometry determines the amount of matter transformed during an electrolysis reaction by measuring the amount of electricity (in coulombs) consumed or produced. 
#It can be used for precision measurements of charge, and the amperes even used to have a coulometric definition.
#Typical coulometric methods use solutions of potassium bromide (halide) and bromine (halogen) in dilute sulphuric acid.  
#The concentration of bromine is measured as a voltage between an indicator electrode and a bromide reference electrode.
#When the measured species is present, the bromine concentration is decreased through reaction. A feedback system then compensates by generator bromine at a generator electrode.
#The current required to regenerate the bromine is directly proportional to the concentration of the measured species.
#The method is extremely sensitive to interference through reaction with other undesired species (typically NO, NO2, O3, sulphur species, Cl2).
#Other species are typically removed through pre-filters.
#This method been used to measure NO2 and SO2.

#Known interferences: Reaction with other gases, typically: NO, NO2, O3, sulphur species, Cl2.

#Fluorescence is the emission of light (luminescence) by a substance that has absorbed light or other electromagnetic radiation (excitation). In most cases, the emitted light has a longer wavelength, and therefore lower energy, than the absorbed radiation.
#Ultraviolet fluorescence specifically refers to the process of a species being excited by ultraviolet light (10nm to 400nm) (species + hv (UV) --> species*).
#The return to a fundamental electronic state of the excited species is made by luminous radiation on a longer wavelength spectrum (species* --> species + hv).
#SO2 is efficiently excited to an excited state (SO2*) by UV light between 190 nm-230 nm, subsequently fluorescing light at approximately 330nm (SO2* --> SO2 +hv(330nm)), which can be measured.

#Typical measurement operation for SO2:
#1. The sample is drawn into the sample bulkhead (typically the sample flows through a hydrocarbon “kicker,” which removes hydrocarbons from the sample by forcing the hydrocarbon molecules to permeate through the tube wall).
#2. The sample then flows into the measurement cell, where pulsating UV light from a light source (typically mercury or zinc vapour lamp) between 190nm-230nm excites the SO2 molecules by the reaction: SO2 + hv (190nm-230nm) --> SO2* . A vacuum diode, UV detector that converts UV light to a DC current is used to measure the intensity of the excitation UV source lamp.
#3. Typically a band pass filter limits the wavelength of the UV source light to approximately 214 nm, and therefore the excitation reaction becomes: SO2 + hv (214nm) --> SO2* 
#4. The amount SO2 converted to SO2* in the sample chamber is dependent on the average intensity of the UV light (Ia) and not its peak intensity because the intensity of UV light is not constant in every part of the sample chamber. Some of the photons are absorbed by the SO2 as the light travels through the sample gas. The equation for defining the average intensity of the UV light (Ia) is: Ia = I0 [1 − exp(− ax(SO2))], Where: I0 = Intensity of the excitation UV light, a = The absorption coefficient of SO2 (a constant), SO2 = Concentration of SO2 in the sample chamber, x = The distance between the UV source and the SO2 molecule(s) being affected (path length). 
#5. SO2* then fluoresces light at a longer (lower energy) wavelength centred at 330nm: SO2* --> SO2 + hv (330nm).
#6. The amount of detectable UV given off by the decay of the SO2* is affected by the rate at which this reaction occurs (k). F = k(SO2*), Where: F = the amount of fluorescent light given off, k = The rate at which the SO2* decays into SO2, SO2* = Amount of excited-state SO2 in the sample chamber. Therefore: (SO2*) -kf --> SO2 + hv (330nm)
#7. The function (k) is affected by the temperature of the gas. The warmer the gas, the faster the individual molecules decay back into their ground state and the more photons of UV light are given off per unit of time. Given that the absorption rate of SO2 (a) is constant, the amount of fluorescence (F) is a result of: a) The amount of SO2* created which is affected by the variable factors: concentration of SO2; intensity of UV light (I0); path length of the UV light(x) and b) The amount of fluorescent light created which is affected by the variable factors: the amount of SO2* present and the rate of decay (k) which changes based on the temperature of the gas.
#8. When and the intensity of the light (I0) is known; path length of excited light is short (x); the temperature of the gas is known and compensated for so that the rate of SO2*decay is constant (k). and; no interfering conditions are present (such as interfering gases or stray light); the amount of fluorescent light emitted (F) is directly related to the concentration of the SO2 in the Sample Chamber.
#9. A Photo Multiplier Tube (PMT) detects the UV given off by the SO2* decay (330 nm) and outputs an analog signal. Several focusing lenses and optical filters ensure that both the PMT and source lamp vacuum diode are exposed to an optimum amount of only the right wavelengths of UV. To further assure that the PMT only detects light given off by decaying SO2* the pathway of the excitation UV and field of view of the PMT are perpendicular to each other and the inside surfaces of the sample chamber are coated with a layer of black teflon that absorbs stray light.
#10. The net result of the careful instrumental precision is any variation in UV fluorescence can be directly attributed to changes in the concentration of SO2 in the sample gas.

#Known interferences: 3rd body quenching (NO, CO2, O2, H2O), light pollution, UV absorption by ozone, other species undergoing ultraviolet fluorescence (poly-nuclear aromatics, NO)

#laser-induced fluorescence (LIF)

#Fluorescence is the emission of light (luminescence) by a substance that has absorbed light or other electromagnetic radiation (excitation). In most cases, the emitted light has a longer wavelength, and therefore lower energy, than the absorbed radiation.
#Laser-induced fluorescence (LIF) is a method where fluorescence is induced by an atom or molecule being excited  by the absorption of laser light.
#The emission light is detected using a photomutiplier tube. The amount of a species present in the sample is proportional to the intensity of the emission light of a specific wavelength and quantification is possible by using calibration data.
#The LIF method has been used mostly in the measurement of hydroxyl and hydroperoxyl radicals, but is also used for measurement of NO/NO2.

#Known Interferences: Laser power modulation (laser excitation could generate OH radicals biasing the measurement). 3rd body quenching.

#See details of method for NO/NO2 here:https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/1999GL900015 and here:http://etheses.whiterose.ac.uk/11668/1/Amy%20Foulds_Final%20MSc%20Thesis.pdf

#vacuum ultraviolet resonance fluorescence (VURF)

#Fluorescence is the emission of light (luminescence) by a substance that has absorbed light or other electromagnetic radiation (excitation). In most cases, the emitted light has a longer wavelength, and therefore lower energy, than the absorbed radiation.
#Vacuum Ultraviolet Resonance Fluorescence is a method where a reasonance lamp excited by reasonance fluorescence discharge (in combiantion with an optical filter) produces photons in the ultraviolet which react with a sample gas, inducing fluorescence in the vacuum ultraviolet (UV radiaion 10nm-200nm), subsequently detected by a photomultiplier tube.
#This method can be employed for CO, with the reasonance lamp emitting UV light between 145nm-151nm, with fluorescence occurring between 160nm-190nm.

#Known interferences: Water vapour, drifts in lamp intensity, continuum raman scattering by O2.

#cavity ringdown spectroscopy (CRDS)

#Based on absorption spectroscopy, Cavity Ringdown Spectroscopy works by attuning light rays to the unique molecular fingerprint of the sample species. 
#By measuring the time it takes the light to fade or "ring-down", you receive an accurate molecular count in milliseconds. 
#The time of light decay, in essence, provides an exact, non-invasive, and rapid means to detect contaminants in the air, in gases, and even in the breath.
#The method is typically employed to measure CO and other greenhouse gases (e.g CO2, CH4, H2O).

#Typical measurement operation:
#1. A Continuous Wave (CW) diode laser emits a directed beam of light energy through an ultra-high reflective mirror into the absorption cell (cavity).
#2. The light reflects back and forth between two ultra-high reflective mirrors multiple times, up to a total path length of 100 kilometers.
#3. Once the photodiode detector “sees” a preset level of light energy, the light source is shuttered or diverted from the cavity.
#4. On each successive pass, a small amount of light or ring-down signal emits through the second mirror and is sensed by the light detector.
#5. Once the light "rings down", the detector achieves a point of zero light energy in milliseconds, and the measurement is complete.    
#6. The computer-controlled system tunes the laser off the absorption peak for the sample species to determine the τ empty value, equivalent to a zero baseline correction. It tunes back to the absorption peak to determine the τ value, dependent on the sample species concentration.
#7. The concentration of the sample species is directly calculated using Beer’s Law. The measured value constitutes an absolute measurement and is unaffected by losses outside the ring-down cavity.

#off-axis integrated cavity output spectroscopy (OA-ICOS)

#CRDS has practical limitations that make it nonideal for many applications. Specifically, the resonant wavelength coupling requires subnanometer optomechanical precision and stability. 
#Thus field service is impractical. In addition, resonant CRDS systems require extreme laser wavelength monitoring and control. 
#These challenges can, at times, be overcome in the laboratory but with a trade-off of increased instrument cost, complexity, and robustness.
#OA-ICOS, originally developed in cooperation with scientists at Harvard University (Cambridge, MA), was created in order to overcome these limitations, while still maintaining extremely high sensitivity and precision. 
#OA-ICOS uses off-axis, nonresonant alignment of the laser beam to the cavity. 
#This beam alignment or trajectory is not unique and is easy to achieve, making OA-ICOS instruments orders of magnitude more robust and less sensitive to thermal changes and vibrations. As a result, OA-ICOS instruments are relatively simple to manufacture and service, inexpensive to build, and robust. 
#The OA-ICOS measurement combines the advantages of CRDS with conventional high-resolution laser absorption spectroscopy by providing direct absorption measurements with optical pathlengths thousands of meters long.
#Unlike CRDS, which enables at most only limited wavelength sampling (discrete jumps between wavelengths), OA-ICOS easily allows continuous scanning of the laser wavelength and thus enables recording of fully resolved absorption spectra. 
#This is a critical advantage that permits OA-ICOS to provide accurate measurements of complex and/or contaminated samples without cross-sensitivity. 
#Moreover, OA-ICOS can be operated at any wavelength from the UV through the IR. As a result, instruments can target the strongest absorption lines, allowing sensitivity below 1 ppt for some gases. Furthermore, because it is an intensity measurement, only OA-ICOS can deliver several decades of linear dynamic range.

#tunable diode laser absorption spectroscopy (TDLAS)

#TDLAS measures the wavelength-dependent absorption of light through a gas medium. 
#As the name implies, the technique usually employs a tunable-wavelength diode laser as the light source.  
#When the wavelength of light matches one absorption line of a gas species present in the sample, the photodetector records a reduction in the light intensity. 
#When the gas concentration is ultra-low, the induced change in transmission becomes extremely small and difficult to detect sufficiently fast. 
#The sensitivity of TDLAS is significantly enhanced by modulating the current of the laser, which leads to a modulation of the wavelength and of the light intensity. 
#The information about the absorption response is then recovered by demodulating the signal from the photodetector at the modulating frequency and at its second-order harmonic.
#The advantage of TDLAS over other techniques for concentration measurement is its ability to achieve very low detection limits
#Apart from concentration, it is also possible to determine the temperature, pressure, velocity and mass flux of the gas under observation

#cavity attenuated phase shift spectroscopy (CAPS)

#Operates on the principle that a specific species efficiently absorbs light at a known wavelength. This is the case for NO2, at 450nm.
#The degree to which the light is absorbed by a specific species is directly related to the species concentration as described by the Beer-Lambert Law (A = εLC; A = Absorbance (mol litres-1), ε = Molar absorptivity (litres mol-1 cm-1), L = mean optical path length of cell, C = species concentration).
#Emitted light in an optical cell is reflected back and forth between two mirrors, building intensity and running a very long path length. The long path length extends the “time” or “life” of the photon, thus providing ample time to measure absorbance when a species is present.
#The method is typically employed for direct measurement of NO2.

#Typical measurement operation for NO2:
#1. The sample is drawn into the sample bulkhead, before being passed into the measurement cell. 
#2. Light is emitted from a blue ultraviolet (UV) light emitting diode (LED) centered at 450 nm (a prominent absorption band for NO2). 
#3. The measurement cell contains high reflectivity mirrors located at either end to provide an extensive optical path length. The optical cell resides in a temperature controlled oven. The oven raises the ambient temperature of the sample gas to 45 degrees Celsius. This mitigates the formation of moisture on the surfaces of the mirrors while also minimiSing changes in the absorption coefficient due to temperature fluctuations.
#4. The CAPS method is unique in that it applies the fundamental optical absorption law in the frequency domain, rather than using relative changes in light intensity as the primary signal. 
#5. UV light from the modulating high intensity LED enters a near confocal optical cell through the rear of mirror A. The intensity of the light, as observed by a vacuum photodiode detector, which is also modulating at a slightly different frequency, located behind Mirror B, builds exponentially in the cell while the LED is ON. The opposite is true when the LED is OFF. Because both mirrors are highly reflective at 450 nm, a prominent absorption band for NO2, the light takes a considerable amount of time to plateau in the absence of the absorbing gas. 
#6. When NO2 is present, the mean path length traveled by the light is significantly reduced. This has two effects on the observed intensity as measured by the detector: a) The light plateau intensity level is lower, b) The light intensity plateaus sooner. Thus, an observed phase shift from the modulating LED is detected. The phase shift is largest when measuring zero air and decreases when NO2 is present.
#7. Both the LED and the Detector are modulated ON and OFF such that the observed signal has a much lower frequency, equal to the difference between the modulated frequencies and is referred to as a beat frequency. The system hardware and software take advantage of this, as it makes it easier to post process the signal using a micro controller. The technique is known as heterodyning.
#8. The instrument translates the phase shift from the presence of absorbing gas into a concentration measurement. Typical absorption techniques of other analysers take a reference and measure value of the light intensity “level” in order to derive concentration and compensate for source drift. Using the CAPS technique the amount of phase shift remains constant for a given concentration, even if the LED drifts over time. The measurement approach offers many advantages over traditional chemiluminescence analysers, such as faster response (single gas stream), lower noise at span and more importantly greater specificity.

#differential optical absorption spectroscopy (DOAS)

#The basic principle used in Differential optical absorption spectroscopy (DOAS) is absorption spectroscopy. DOAS allows the quantitative determination of multiple atmospheric trace gas concentrations by recording and evaluating the characteristic absorption structures (lines or bands) of the trace gas molecules along an absorption path of known length in the open atmosphere, following the Beer-Lambert law (I = Io e−KLC; K = molecular absorption coefficient at STP, L = optical path length of cell, C = species concentration , I = light intensity of sample gas, Io = light intensity of sample without measured species (reference gas) ).
#The wavelength of light where a distinct absorption peak occurs is determined for analyte. A wavelength on either side of the absorption peak is next determined. The intensity of a light source at wavelength is measured and then the intensity is measured again after the light passes through the analyte. The difference of the intensities is proportional to the concentration to the analyte.
#DOAS is a long path measuring technique. Measurements can be made in an optical pathway from 1 to 10 kilometers.
#The method measures the average concentration of a species along the path length, not for any single molecule.
#In the real atmosphere, multiple effects contribute to the overall attenuation of the light. In particular, aerosols and clouds scatter light and thereby reduce the intensity of the direct beam while increasing intensities measured in other directions. Also, there rarely is only one absorber relevant at a given wavelength and this also needs to be accounted for. 
#The solution to this problem lies in the use of measurements at several wavelengths. Each molecule has a characteristic absorption spectrum (its spectral fingerprint) and therefore, simultaneous measurements at different wavelengths enable the separation of the contributions of the different absorbers. This is what DOAS does.
#Scattering by aerosols also needs accounting for. Their extinction cross-sections can be approximated by power laws (λ**-4 for Rayleigh scattering and λ**-1..0 for Mie scattering), the coefficients of which can be determined in the fit. The basic principle behind the separation of aerosol extinction and trace gas absorption is that the latter are identified using those parts of their absorption cross-sections that vary rapidly with wavelength. 
#The more slowly varying parts of the absorption can not be separated from extinction by aerosols which is why the absorption cross-sections are often high pass filtered before use in a DOAS retrieval.
#In addition to their effect on the spectral distribution of the intensity measured, aerosols can also have a significant impact on the light path of scattered light. This has to be modelled explicitly when computing the airmass factors for the light path correction.
#The DOAS technique is characterised by the following: 
#(a) measuring the transmitted light intensity over a relatively (compared to the width of an absorption band) broad spectral interval; 
#(b) high‐pass filtering of the spectra to obtain a differential absorption signal and eliminating broad‐band extinction processes such as Rayleigh and Mie scattering (RS and MS); 
#(c) quantitative determination of trace column densities by matching the observed spectral signatures to prerecorded (reference) spectra by, for instance, least‐squares methods.
#DOAS instruments are often divided into two main groups: passive and active ones. The active DOAS system such as longpath(LP)-systems and cavity-enhanced(CE) DOAS systems have their own light-source, whereas passive ones use the sun as their light source, e.g. MAX(Multi-axial)-DOAS. Also the moon can be used for night-time DOAS measurements, but here usually direct light measurements need to be done instead of scattered light measurements as it is the case for passive DOAS systems such as the MAX-DOAS.

#Typical measurement operation:
#1. The positioning of the emitter and the receiver define the monitoring path. The light source in the emitter is a high-pressure xenon lamp. This type of light source radiates an almost smooth spectrum ranging from approximately 200 nm up to 500 nm, and from about 1200 to 3000 nm. Within these ranges a number of gaseous substances show specific absorption spectra. The lamp spectrum is however not perfectly smooth, but the remaining "hills" in the spectral output are being taken care of in the evaluation.
#2. The emitted light beam is directed towards the receiver, and on its way the intensity is affected by scattering and absorption in molecules and particles.
#3. To ascertain the initial intensity (Io) of the light source across the path, there are typically two approaches: (a) Use of measurements at different light paths. If it is possible to take two measurements with the same initial intensity but at different light path lengths L, the dependence on the initial intensity cancels if one looks at the ratio of the two measurements. This approach is e.g. used in zenith-sky DOAS, where a measurement at low sun (long light path through the atmosphere) is analysed with a measurement taken at high sun (short light path). (b) Use of measurements at different wavelengths. In this approach, one exploits the fact that many molecules have structured spectra and light at different wavelengths experiences different absorption strengths. If the initial intensity does not vary with wavelength, one can look at the ratio of two measurements at different wavelengths to remove the dependence on Io. This approach is often used in long-path measurements which employ a lamp. It also is one reason to call this method differential as changes in absorption are used.
#4. From the receiver the captured light is led via an opto-fibre to the analyser. The function of the fibre is only to avoid exposing the opto-analyser to dust, high humidity, temperature variations, etc.
#5. When the light reaches the analyser, it enters a spectrometer. Inside the spectrometer, a grating refracts the light into its wavelength components. The refracted light is then projected onto a rapid scanning slit in front of a photo-multiplier detector or an infrared sensitive diode, where a selected part of the spectrum is detected. The scanning slit device makes it possible to record all wavelengths separately.
#6. As the grating is moveable, any chosen part of the spectrum can be detected. The wavelength window can thus be optimised for a certain component, with respect to parameters such as sensitivity and interfering pollutants. Approximately 100 scans per second are recorded.
#7. The current from the detector is converted into digital signals by a 12 bit analogue-to-digital converter, and the signal is stored and accumulated in a multi-channel register. The detected spectrum is typically 40 nm wide in the UV range and approximately twice as wide in the IR range. Each scan is digitised into 1000 points.
#8. Each pollutant is monitored during a time period entered by the operator. When the data accumulation is finished, the evaluation process is started. At the same time the next data accumulation period starts.

#Known interferences: Interference by miscellaneous atmospheric constituents. Heavy rain and fog, and even high humidity. Atmospheric turbulence, such as that from thermal-induced effects, can distort reflections. Anything that interrupts the path of the laser will cause some interference (i.e., animals, cars, planes, etc.).

#electrochemical membrane diffusion (EMD)

#Methodology developed specifically for measurement of NH3: https://www.sciencedirect.com/science/article/pii/S0003267003012650?via%3Dihub
#Gas is sampled in a sampler comprising two opposite channels separated by a gas permeable, water repellent polypropylene membrane. 
#Subsequently, the acid sample solution is pumped into a selector where an alkaline solution is added to ionize all sampled ambient acid gasses, resulting in an enhanced selectivity. 
#In the selector, the ammonia can diffuse through a second membrane into a purified water stream where an electrolyte conductivity sensor quantifies the resulting ammonium concentration. 
#The realized system is shown to be selective enough not to be influenced by normal ambient carbon dioxide concentrations. 
#Experiments with a gas flow of 3 ml/min, containing ammonia concentrations ranging from 9.8 to 0.3 ppm in a nitrogen carrier flow, into a 15 μl/min sample solution flow and finally into a 5 μl/min purified water stream have been carried out and show that the system is sensitive to ammonia concentration below 1 ppmv.

#photoacoustic spectroscopy (PS)

#Gaseous samples are continuously drawn through a measurement cell, where they are interrogated spectroscopically with the output radiation of a carbon dioxide/tunable quantum cascade laser. 
#This is used in conjunction with a highly sensitive acoustic detector to measure trace gas concentrations. Laser tuning is accomplished using proprietary algorithms that do not require the use of a spectrometer or other wavelength measurement device. 
#The laser is tuned to a known gaseous absorption line and passed through a cell containing the gas sample. If the trace gas species is present, the gas sample will be slightly heated. This heating can be measured very accurately and linearly by microphones in the cell and the amplitude of the electrical signal from the microphones correlate with the trace gas concentration. 
#If there is no trace gas present, there will be no signal from the microphone. This is, therefore, the highly desirable "zero-background measurement". 
#Traditional spectroscopic methods measure the total power of the laser beam with and without a sample in the path. For very weak attenuations that result from trace gas concentrations, this process requires taking the difference of two large numbers, each with a finite uncertainty, to compute a small real number. This complication is avoided using this method.
#This method has been used to measure NH3.

#non-dispersive infrared absorption (luft) (NDIR-L)

#Operates on the principle that a specific species efficiently absorbs IR light at a known wavelength in the IR range. This is the case for CO, at 4.7um
#The degree to which the IR light is absorbed by a specific species is directly related to the species concentration as described by the Beer-Lambert Law (I/Io = e−KLC; K = molecular absorption coefficient at STP, L = optical path length of cell, C = species concentration , I = light intensity of sample gas, Io = light intensity of sample without measured species (reference gas) ).

#Typical measurement operation for CO:
#1. The sample is drawn into the through the sample bulkhead
#2. IR radiation from a IR source (at 4.7 um) is passed through a rotating shutter creating a series of pulses.
#3. These pulses are split simultaneously into 2 measurement cells. One cell contains the sample gas, termed the sample stream (I), and cell contains a non-absorbing gas at the specific wavelength (i.e N2), termed the reference stream (Io).
#4. Both the pulses then exit the cells and fall on a IR photo-detector. 
#5. The intensities of 4.7 um light transmitted through the sample (I) and CO-free reference beams (Io) are related to the concentration (C) of CO in the sample gas stream according to the Beer-Lambert Law.
#6. The analyser’s microprocessor calculates the absolute concentration in molecules cm-3, and is then converted to a mixing ratio using in-instrument measured sample temperature and pressure.

#Known Interferences:
#Water vapour and CO2

#non-dispersive infrared absorption (gas-filter correlation) (NDIR-GFC)

#Operates on the principle that a specific species efficiently absorbs IR light at a known wavelength in the IR range. This is the case for CO, at 4.7um
#The degree to which the IR light is absorbed by a specific species is directly related to the species concentration as described by the Beer-Lambert Law (I/Io = e−KLC; K = molecular absorption coefficient at STP, L = optical path length of cell, C = species concentration , I = light intensity of sample gas, Io = light intensity of sample without measured species (reference gas) ).
#The methodology also applies the gas-filter correlation technique. This is applied as water vapour and CO2 absorb light at 4.7 um as well as CO, and ensures measurements are specific for CO.

#Typical measurement operation for CO:
#1. The sample is drawn into the through the sample bulkhead
#2. IR radiation from a IR source (at 4.7 um) is passed through a multi-pass cell length with sample gas. The sample cell uses mirrors at each end to reflect the IR beam back and forth through the sample gas a number of times. The total length that the reflected light travels is directly related to the intended sensitivity of the instrument. The lower the concentrations the instrument is designed to detect, the longer the light path must be in order to create detectable levels of attenuation.
#A gas-filter correlation wheel is combined with this system. This wheel contains three parts to increase measurement accuracy: CO, N2 and the mask:
#    The CO window contains saturation (40 %) of CO which acts as a reference beam – absorbing a known amount of light.
#    The N2 window, containing 100 % N2, does not absorb IR at 4.7 um at all and is used during normal CO measurement.
#    The mask totally blocks the light source and is used to determine background signals, the strength of other signals relative to each other and the background.
#3. The IR source is passed through the rotating filter wheel before entering the multi-pass cell: 
#    When the light beam is intercepted by the CO portion of the wheel, the carbon monoxide, which is at relatively high concentration, absorbs all wavelengths that are co-specific, creating and emanating light beam that is “CO blind”. This “optically scrubbed” portion of the beam is designated the Reference beam (Io).
#    The nitrogen-intercepted portion of the beam, which is “CO sensitive”, is designated the sample beam (I). 
#    In the absence of CO no attenuation of the Io and I portion of the beam will occur.
#    Species other than CO will cause an equal attenuation of both I and Io portions of the beam. 
#    If CO is present in the air being sampled, then the beam portion generated by the CO side of the wheel will experience no attenuation, but the beam portion generated by the N2 portion of the wheel will be attenuated to the degree dictated by the level of CO concentration.
#    When the light beam is intercepted by the mask, this is labelled the "dark portion". This provides a zero light reference point to compensate for the "dark current" of the detector.
#4. A band pass filter is fitted on the exit of the sample cell, allowing only 4.7 um wavelength light to pass.
#5. The infrared radiation then exits the optical cell and falls on an IR photo-detector. 
#6. The intensities of 4.7 um light transmitted through the sample (I) and CO-free reference beams (Io) are related to the concentration (C) of CO in the sample gas stream according to the Beer-Lambert Law.
#7. The analyser's microprocessor records the imbalance between the I and Io beams portions and performs a data linearisation, calculating the absolute concentration in molecules cm-3, and is then converted to a mixing ratio using in-instrument measured sample temperature and pressure.

#Known Interferences:
#Water vapour and CO2

#non-dispersive infrared absorption (cross-flow modulation) (NDIR-CFM)

#Operates on the principle that a specific species efficiently absorbs IR light at a known wavelength in the IR range. This is the case for CO, at 4.7um.
#The degree to which the IR light is absorbed by a specific species is directly related to the species concentration as described by the Beer-Lambert Law (I/Io = e−KLC; K = molecular absorption coefficient at STP, L = optical path length of cell, C = species concentration , I = light intensity of sample gas, Io = light intensity of sample without measured species (reference gas) ).
#The methodology also applies the cross-flow modulation technique. This is applied as water vapour and CO2 absorb light at 4.7 um as well as CO, and ensures measurements are specific for CO.

#Typical measurement operation for CO:
#1. The sample is drawn into the through the sample bulkhead
#2. IR radiation from a IR source (at 4.7 um) is passed through a measurement cell.
#3. Fixed amounts of the sample gas (I) and the reference gas (Io) are injected alternately into the measurement cell (cross-flow modulation). This has the advantage over the gas-filter correlation technique that, in principle, when analyzing small amounts of gas there is no generation of zero-drift. An additional advantage is that the elimination of rotary sectors precludes the need for optical adjustment. These features assure greatly improved stability over long periods of measurement. The reference gas is generated by purging the sample through an oxidation process, where an oxidizing catalyst burns the CO to CO2. These features eliminate interference from other elements, resulting in highly accurate measurements.
#4. The infrared radiation then exits the optical cell and falls on an IR photo-detector. 
#5. The intensities of 4.7 um light transmitted through the sample (I) and CO-free reference beams (Io) are related to the concentration (C) of CO in the sample gas stream according to the Beer-Lambert Law.
#6. The analyzer’s microprocessor calculates the absolute concentration in molecules cm-3, and is then converted to a mixing ratio using in-instrument measured sample temperature and pressure.

#Known Interferences:
#Water vapour and CO2

#dual isotope fluorescence (DIF)  

#This method is an adaption of non-dispersive infrared absorption for the measurement of CO.
#A broadband of infrared source is used to stimulate fluorescence of C16O and C18O, contained in a sealed cell.
#The stimulated radiation is passed first through a filter that alternately passes radiation from only one of the isotopic sources and is then passed through the sample cell to a solid state detector.
#Because almost all atmospheric CO consists of the C16O isotope, only radiation produced by the C16O source will be absorbed by the CO in the sample.
#The radiation produced by the C18O source is used as a reference beam to account for interference with H2O, or other interferants.

#Known Interferences:
#Water vapour and CO2

#fourier transform infrared spectroscopy (FTIR)

#Fourier Transform Infrared Spectroscopy (FTIR) is an analytical technique used to identify organic (and in some cases inorganic) materials. 
#This technique measures the absorption of infrared radiation by the sample material versus wavelength. 
#The infrared absorption bands identify molecular components and structures.
#When a material is irradiated with infrared radiation, absorbed IR radiation usually excites molecules into a higher vibrational state. 
#The wavelength of light absorbed by a particular molecule is a function of the energy difference between the at-rest and excited vibrational states. 
#The wavelengths that are absorbed by the sample are characteristic of its molecular structure.
#The FTIR spectrometer uses an interferometer to modulate the wavelength from a broadband infrared source. 
#A detector measures the intensity of transmitted or reflected light as a function of its wavelength. 
#The signal obtained from the detector is an interferogram, which must be analyzed with a computer using Fourier transforms to obtain a single-beam infrared spectrum. 
#The FTIR spectra are usually presented as plots of intensity versus wavenumber (in cm-1). Wavenumber is the reciprocal of the wavelength. 
#The intensity can be plotted as the percentage of light transmittance or absorbance at each wavenumber.

#gas chromatography (GC)

#Gas chromatography (GC) is a method used for separating and analysing compounds that can be vaporized without decomposition.
#A sample solution is injected into a instrument, entering a gas stream which transports the sample (mobile phase) into a separation tube known as the "column".
#The mobile phase is a carrier gas, usually an inert gas such as helium or an unreactive gas such as nitrogen. Helium remains the most commonly used carrier gas in about 90% of instruments although hydrogen is preferred for improved separations.
#The column consists of a microscopic layer of liquid or polymer on an inert solid support a microscopic layer of liquid or polymer on an inert solid support (stationary phase), inside a piece of glass or metal tubing, placed inside a piece of glass or metal tubing.
#Once inside the column, the gaseous compounds being analysed interact with the walls of the column coated with a stationary phase. This causes each compound to elute at a different time, known as the retention time of the compound. 
#The comparison of retention times is what gives GC its analytical usefulness.
#If greater separation of compounds is required, multiple distinct columns can be used for this purpose.

#Almost all methods involving GC are typically paired with a detector of some description to measure the GC separated components.
#These detectors are various in number, and are outlined in detail below.
#Typically GC-detector analysis is used for the separation of short lived hydrocarbon species. 

#Typically sample processing is undertaken before the passing of samples into the GC. 
#Typically this emcompasses the preconcentration, or passing samples through sorbent traps.

#If no other information is given, it is assumed all GC-detector analysis is done via injection and do not operate online (i.e. not continuously).

#gas chromatography - electron capture detection (GC-ECD)

#The Electron Capture Detector (ECD) is a selective detector for electro-negative compounds, especially halogens.
#A beta-ray radio active source which can ionize the carrier gas is located in the detector. 
#A current is produced between two electrodes in the detector supplied with a potential difference and this is monitored as a continuous background current. 
#When there are electro-negative components present in the carrier gas, the background current is reduced because these components capture electrons.
#This change in the background current is registered as 'holes' in the background. 
#Since it concerns very small holes, the background current should not be too high. 
#Therefore the (linear) dynamic range of the ECD is often limited.

#gas chromatography - flame ionisation detection (GC-FID)

#Flame ionisation detection operates in the exact same way as it does as a standalone method, only in this instance coupled to a GC.
#It is based on the principle of the generation of an electrical current that is proportional to the rate of ion formation, dependent on the concentrations of species in the sample gas.

#A limitation of GC-FID is that the retention time is merely characteristic of a compound and certainly not adjudicative or confirmatory of the specificity of that compound.
#This means a peak at a given retention time is not a unique qualitative measure (to the exclusion of every other compound in the universe).

#gas chromatography - photoionisation detection (GC-PID)

#Gas Chromatography - Photoionisation Detection (GC-PID) is a technique used to analyse a wide range of aromatic hydrocarbons and other organic compounds. 
#A typical application is the analysis of hydrocarbon pollution of water. The PID uses ultraviolet light to ionize the components exiting the column. 
#The ions are collected by electrodes and the current generated measures the concentration. 
#As common with other GC techniques, a carrier gas is required with low Water and Oxygen impurities since Water and Oxygen can interact with the stationary phase and cause significant problems such as high baseline noise and column bleed in the output gas chromatogram which both reduces the analyser sensitivity and decreases column lifetime.  
#Helium and Nitrogen are normally used.

#gas chromatography - mercuric oxide reduction detection (GC-HgO) 

#Mercuric oxide (HgO) reduction is a detection method available for hydrogen, carbon monoxide, and other reducing gases.
#It uses mercuric oxide reaction tube and a mercury lamp in a heated UV detector cell. 
#The reaction tube is heated to 260-300oC. 
#Located immediately downstream of the reaction tube, the UV detector cell is heated to 170degC. 
#The UV detector cell is equipped with a mercury lamp and a UV photodiode. When a reducing gas such as carbon monoxide elutes from the GC column, it reacts with the HgO to form gaseous mercury vapor, which is then swept into the UV cell. 
#The gaseous mercury absorbs the UV light from the mercury lamp as it flows through the cell. The change in transmittance is converted by the data system into an absorbance output, which is linearly proportional to the amount of reducing gas.

#gas chromatography - dual flame ionisation detection (GC-DFID)

#To limit the main limitation of GC-FID, i.e. lack of specificity, it is possible to add another GC column and analyse the sample concurrently on both columns.
#This can be done by adding a y-splitter that will take the single injection made into the injector port and divide the sample into two different pathways with one part of the sample going to one column for analysis and the second part going to another column for analysis.
#The two different columns are given two different stationary phases, which provides different separation of the analytes (both in terms of retention time and possibly even eluting order). 
#This different eluting order and different retention times only minimises, but does not entirely eliminate the possibility of co-elution as again, the resolving (separating) power of the method is only determined by one non-unique measure which is the two retention times. 
#Even though there is a change in the eluting order potentially and the retention times are different based upon the stationary phase composition, again, remains the basic limitation of GC-FID remains in that a retention time is merely characteristic of the analyte, but is certainly not confirmatory.
#With dual detectors, the concentration of the analyte(s) of interest is determined from two calibration curves, and can serve as quantitative confirmation.

#gas chromatography - mass spectrometry (GC-MS)

#One of the most common detector types is a mass spectrometer.
#Mass spectrometry is the study of matter through the formation of gas-phase ions (with or without fragmentation) that are detected and characterised by their mass to charge ratios (m/z) and relative abundances. 
#The technique basically studies the effect of ionizing energy on molecules. It depends upon chemical reactions in the gas phase in which sample molecules are consumed during the formation of ionic and neutral species.
#A mass spectrometer generates multiple ions from the sample under investigation, it then separates them according to their specific mass-to-charge ratio (m/z), and then records the relative abundance of each ion type.
#The first step in the mass spectrometric analysis of compounds is the production of gas phase ions of the compound, basically by electron ionization. 
#This molecular ion undergoes fragmentation. Each primary product ion derived from the molecular ion, in turn, undergoes fragmentation, and so on. 
#The ions are separated in the mass spectrometer according to their mass-to-charge ratio, and are detected in proportion to their abundance. 
#A mass spectrum of the molecule is thus produced. It displays the result in the form of a plot of ion abundance versus mass-to-charge ratio. 
#Ions provide information concerning the nature and the structure of their precursor molecule. 
#In the spectrum of a pure compound, the molecular ion, if present, appears at the highest value of m/z (followed by ions containing heavier isotopes) and gives the molecular mass of the compound.

#There are a variety of different mass spectrometer types (almost never reported in observational data). 
#The most important difference among various mass spectrometers is the type of the analyser. 
#It is a fundamental characteristic of an instrument, and can not be modified. 
#The main analyzer types are: quadrupole, ion trap, time-of-flight (TOF), sector and Fourier-transform (FT) type instruments. 
#Some analysers are inherently capable for MS–MS (like ion trap or FT-MS), some others can be connected in tandem, offering MS–MS capabilities. 
#The most common analyzers (quadrupoles, sectors and in most respect ion traps) pass one ion (a given m / z ratio) at any one time, and filter out all other ions (which are lost for analysis).

#To obtain a mass spectrum, the analyser scans through the mass range of interest. 
#The consequence of this scanning is, that the sensitivity of detecting a given ion is much less compared to the case, when only a given mass is monitored (when the analyser stands still to pass only one ion). 
#These analyzers can be used in two ways: Either monitoring a given ion (with full sensitivity), or scanning the mass range (with loss of sensitivity) to obtain a mass spectrum. 
#Other analyzer types (TOF, FT-MS, in some respect ion traps and special sector instruments) can simultaneously detect all ions in a mass range, so there is no need for scanning. 
#In this case the full sensitivity is obtained irrespectively if one ion or a full mass spectrum is studied. 
#At present quadrupole-type instruments are most widespread. These are simple to use, cheap and rugged, good for basic GC–MS studies and for quantitation.

#In many instances the phrase 'mass selective detector' or 'MSD' is be used in place of mass spectrometer.
#However, there is no fundamental difference between mass selective detection and mass spectrometry; the name 'mass selective detection' is part of a marketing strategy, and implies a simple, relatively cheap instrument.
#Therefore all reported instances of MSD are grouped under mass spectrometry.

#gas chromatography - mass spectrometry - flame ionisation detection (GC-MS-FID)

#In some instances, the simultaneous application of different detectors is extremely advantageous.
#For example, the combination of an a flame ionisation detector (which has a wide quantitation response range) with a mass spectrometer (which obtains qualitative information of unknown compounds) enables identification of volatile and semi-volatile compounds at trace levels.
#A splitter is applied after the GC column, splitting output to an FID and MS detector. 
#Using such a system enables users to obtain both a TIC (Total Ion Chromatogram) and FID chromatogram at the same time, giving the advantages of both detection types simultaneously.
#By acquiring abundant information at the same time, the detector splitting system saves both cost for analytical instruments and columns, and operators' time.

#high performance liquid chromatography - mass spectrometry (HPLC-MS)

#Liquid chromatography (LC) is a separation process used to isolate the individual components of a mixture. 
#This process involves mass transfer of a sample through a polar mobile phase and non-polar stationary phase.
#The device is a column packed with the porous medium made of a granular solid material (i.e., stationary phase), such as polymers and silica, where the sample is injected and the solvent (i.e., mobile phase) passes to transport the sample.
#When a sample is injected, it is adsorbed on the stationary phase, and the solvent passes through the column to separate the compounds one by one, based on their relative affinity to the packing materials and the solvent. 
#The component with the most affinity to the stationary phase is the last to separate. This is because high affinity corresponds to more time to travel to the end of the column.

#High-performance liquid chromatography (HPLC), also known as high-pressure liquid chromatography, is an advanced type of LC. 
#HPLC is amenable to a wide range of applications, such as pharmaceuticals and food analysis. It is especially useful for low or non-volatile organic compounds, which cannot be handled with gas chromatography.
#The difference between traditional LC and HPLC is that the solvent in LC travels by the force of gravity. 
#In HPLC, the solvent travels under high pressure obtained by means of a pump to overcome the pressure drop in the packed column, which reduces the time of separation.

#high performance liquid chromatography - ultraviolet detection (HPLC-UV)

#The most commonly used detector in liquid chromatography is ultra violet absorption
#A UV detector uses a molecules ability to absorb ultraviolet light – detectors can use a single wavelength or variable wavelengths which can be more sensitive. 
#By passing UV light through the individual components of an eluting sample mix and measuring the amount of UV light absorbed by each component, you can determine the individual quantities of each component.

#proton transfer reaction

#An alternative to using gas chromatography for the separation of compounds is proton transfer reaction. 
#The main advantage of proton transfer reaction is that in most of cases it does not induce any significant fragmentation, and when it does only few fragments are produced. 
#Soft-ionisation results in only one or two characteristic ions, and the matrix of signals is much less complex than in other mass spectrometric techniques.
#Upon entering a PTR device, gas-phase molecules are ionised (by an ionisation source), transferring a proton (H3O+, O2+, NO+, or others) to the molecules of interest.
#For the proton transfer reaction to occur, the ionised molecule must have a higher proton affinity than the transferred proton (i.e. H3O+).
#Fast switching between reagent ions can also be used to separate isomeric compounds (molecules containing same atoms, but having different conformation), which have different reactivity with the various reagent ions.
#The ions produced in this reaction are subsequently detected by a mass analyser.
#Using PTR, comes with the advantage that ambient air can be directly sampled, without any prior sample processing (i.e. preconcentration). 

#------------------------------------
#proton transfer reaction - mass spectrometry (PTR-MS)

#Almost always PTR is coupled with a mass spectrometer for detection (PTR-MS).
#Proton Transfer Reaction - Mass Spectrometry characterises compounds according to their mass-to-charge ratio. 
#A great advantage of PTR-MS is that common air constituents (N2, O2) have low proton affinities and do not react, thus no diluting buffer gas is required.
#PTR-MS is the most widely used method for real-time monitoring of volatile organic compounds (VOCs) at low concentrations.

#Unless another specific detector is stated, where Proton Transfer Reaction is given as a methodology, it will be assumed that it uses Mass Spectrometry detection.

#Passive methods (colorimetry, spectrophotometry, ion chromatography, continuous flow analysis, titration)

#It is not always possible to measure atmospheric composition using a automatic, continuous methodology. 
#Typically automated instrumentation is expensive, needs dedicated laboratory space, and requires regular measurement maintenance.
#There is a growing trend in the use of passive methodologies, which are much cheaper, require less maintenance and can be used in high volume. 

#These methods typically involve 2 or more sample steps. Typically these are:
#1. Air is sampled passively, and a desired compound(s) is first trapped (through either physical or chemical means) (passive phase).
#2. The trapped species concentration is determined in a laboratory, using a suitable methodology (typically done in batch) (analysis phase). 

#The in-lab analysis phase methodologies are almost always one of the following: 
#1. colorimetry
#2. spectrophotometry
#3. ion chromatography 
#4. continuous flow analysis
#5. titration

#---------------------
#colorimetry (CO)

#Colorimetry fundamentally refers to the determination of species concentrations based on the colour of a solution.
#Intrinsically, this is based on Beer-Lambert's law, according to which the absorption of light transmitted through the medium is directly proportional to the medium concentration.
#However, the way this colour is extrapolated to give a concentration, adds complexity to the definition of this method.
#In the most basic of senses the colour can be analysed manually, with the concentration directly extrapolated through a colour chart, or given through the length of colour stain on a glass tube from reagent reaction.
#The determination can be done in a more specific, automated fashion through the use of colorimeters.
#In a colorimeter, a beam of light with a specific wavelength is passed through a solution via a series of lenses, which navigate the colored light to the measuring device. 
#This analyses the color compared to an existing standard. A microprocessor then calculates the absorbance or percent transmittance.
#If the concentration of the solution is greater, more light will be absorbed, which can be identified by measuring the difference between the amount of light at its origin and that after passing the solution.
#Colorimeters are usually portable and use LED light sources and color filters. As a result, they operate at fixed wavelengths and can only accommodate tests that incorporate those wavelengths.   

#Unless additional information is given, make assumption colorimetry method uses instrumental injection of sample species, following chemical reaction with a reagent.

#Not QA accepted measurement technique for multiple species due to dominance of other more accurate techniques in measuring these species

#spectrophotometry (SP)

#Spectrophotometry is also based on Beer-Lambert's law, where the absorption of light transmitted through the medium is directly proportional to the medium concentration.
#The main disadvantage and limitation of the spectrophotometry is its low selectivity. The measurement of absorbance is burden by interferences derived from others components of sample.
#A spectrophotometer is a photometer (a device for measuring light intensity) that can measure intensity as a function of the color, or more specifically, the wavelength of light.  
#Spectrophotometers are usually bench top instruments and use light sources that can produce a range of wavelengths, use monochromators to select for a desired wavelength. As a result, spectrophotometers can be used for a broad range of tests. 

#The distinction between spectrophotometry and colorimetry is not always clear. 
#Colorimeters and spectrophotometers both measure sample absorbance to determine analyte concentrations. 
#The main distinction is that a spectrophotometer can be set to measure % transmittance or absorbance over a wide range of wavelengths, whereas a colorimeter determines absorbance at specific, visible, wavelengths.

#ion chromatography (IC)

#Ion chromatography (or ion-exchange chromatography) is a chromatography process that separates ions and polar molecules based on their affinity to the ion exchanger. 
#It works on almost any kind of charged molecule—including large proteins, small nucleotides, and amino acids. However, ion chromatography must be done in conditions that are one unit away from the isoelectric point of a protein. 
#The two types of ion chromatography are anion-exchange and cation-exchange. 
#Cation-exchange chromatography is used when the molecule of interest is positively charged. The molecule is positively charged because the pH for chromatography is less than the pI. In this type of chromatography, the stationary phase is negatively charged and positively charged molecules are loaded to be attracted to it. 
#Anion-exchange chromatography is when the stationary phase is positively charged and negatively charged molecules (meaning that pH for chromatography is greater than the pI) are loaded to be attracted to it.

#Typical Operation:
#1. A sample of the mixture to be analyzed (analyte) is injected into a carrier fluid (the eluent).
#2. The combination is passed through a column containing a stationary fixed material (adsorbent).
#3. Compounds contained in the analyte are then partitioned between the stationary adsorbent and the moving eluent/analyte mixture.
#4. Different dissolved materials adhere to the adsorbent with different forces. The ones that adhere strongly are moved through the adsorbent more slowly as the eluent flows over them. As the eluent flows through the column the components of the analyte will move down the column at different speeds and therefore separate from one another.
#5. A detector is used to analyze the output at the end of the column. There are various detectors, typically they use an electrical conductivity detector.
#6. Each time analyte molecules/ions emerge from the chromatography column the detector generates a measurable signal which is usually printed out as a peak on the chromatogram.
#7. A suppressor is used to reduce the background conductance of the eluent and at the same time enhance the conductance of the sample ions.

#continuous flow analysis (CFA)

#In continuous flow analysis (CFA), a sample is injected into a flowing carrier solution passing rapidly through small-bore tubing. 
#The sample is mixed with a reagent, which reacts with the sample to develop a color and determine the sample concentration (typically by spectrophotometry).
#The use of carefully controlled flow conditions ensures that the color development reaction is reproducible, so that the color measurement need not wait until the reaction has gone to completion.
#There are several technologies of CFA such as segmented flow analysis (SFA), which uses turbulent flow conditions that allow for complete sample dispersion. 
#Other technologies include flow injected analysis (FIA) and sequential injection analysis, which uses laminar flow existing in the narrow-bore tubing to mix with the reagent to eliminate the need for air bubble partitioning.
#Most continuous flow analyzers depend on color reactions using a flow through photometer, however, also methods have been developed that use ISE, flame photometry, ICAP, fluorometry, and so forth.

#titration (TI)

#Titration is a common laboratory method of quantitative chemical analysis that is used to determine the concentration of an identified analyte. 
#Since volume measurements play a key role in titration, it is also known as volumetric analysis. 
#A reagent, called the titrant or titrator is prepared as a standard solution. 
#A known concentration and volume of titrant reacts with a solution of analyte or titrand to determine concentration. 
#The volume of titrant reacted is called titration volume.
#Titration can be also done automatically, in a continuous process.

#Typical measurement operation:
#1. A typical titration begins with a beaker or Erlenmeyer flask containing a very precise volume of the analyte and a small amount of indicator (such as phenolphthalein) placed underneath a calibrated burette or chemistry pipetting syringe containing the titrant. 
#2. Small volumes of the titrant are then added to the analyte and indicator until the indicator changes color in reaction to the titrant saturation threshold, reflecting arrival at the endpoint of the titration. 
#3. Depending on the endpoint desired, single drops or less than a single drop of the titrant can make the difference between a permanent and temporary change in the indicator.    
#4. When the endpoint of the reaction is reached, the volume of reactant consumed is measured and used to calculate the concentration of analyte by: Ca = Ct*Vt*M / Va  ;where Ca is the concentration of the analyte, typically in molarity; Ct is the concentration of the titrant, typically in molarity; Vt is the volume of the titrant used, typically in liters; M is the mole ratio of the analyte and reactant from the balanced chemical equation; and Va is the volume of the analyte used, typically in liters.

#Unless additional information is given, make assumption titration uses instrumental injection of sample species, following chemical reaction with a reagent.

#Not QA accepted measurement technique for SO2 due to dominance of other more accurate techniques in measuring this species

#See more details about method for SO2:https://www3.epa.gov/ttnemc01/ctm/ctm013B.pdf

#thermal reduction - chemiluminescence (TR-CL)

#Indirect method for the measurement of nitrate (NO3-) through the conversion of NO3- to NOy by thermal reduction, which is then measured by chemiluminescence, as a result of the reaction of NO with ozone (NO+O3 --> NO2*+O2).
#The nitrate is converted by drawing a continuous stream of sample across a hot reactive surface that reduces nitrate particles in the sample stream to NOy
#The concentrations of nitrate in the ambient air are then quantified by comparing the signal produced when aerosol-laden sample is drawn directly into the converter to a background signal that is produced when the sample stream is run through a high-efficiency particulate aerosol filter that removes the nitrate before conversion. 
#The difference in signal between the filtered and unfiltered sample can be attributed to the NOy that is formed from nitrate particles in the unfiltered sample stream. 
#By routinely switching between the filtered and unfiltered sample streams, the instrument readings can be continuously adjusted or corrected for changes in background signal that might be produced by traces of NOy or other interfering gases. 
#This frequent adjustment for changes in background signal improves the system stability, which in turn improves the limit of detection.

#aerosol mass spectrometry (AMS)

#This method is a variation of the Mass Spectrometry method to analyse gas-phase species, specific for aerosols.
#In Aerosol Mass Spectrometry, aerosol particles are – together with a small fraction (10−7) of a carrier gas – directed onto the tungsten vaporizer, typically heated to a temperature of 550–600 ◦C.
#Non-refractory material flash-vaporises, and the emerging vapor is electron-impact-ionised (70 eV) for subsequent analysis with a quadrupole or a time-of-flight mass spectrometer.
#In addition to the measurement of the aerosol beam (“beam-open” mass spectrum), also the instrument background is measured with the aerosol beam blocked (“beam-closed” mass spectrum). 
#The particle contribution is calculated from the difference of both measurements (“difference” spectrum), assuming that all particle components vaporize quickly compared to the beam-open–beam-closed cycle length. 
#For calculation of mass concentrations of species from the difference spectrum, each individual m/z is associated with one or several of these species.
#For the standard analysis of the unit mass resolution spectra, these associations are listed in the “frag table”, which needs to be adapted for special measurement situations by the user. 
#Measurements with the high-resolution time-of-flight AMS (HR-ToF-AMS) allow the quantification of individual signals in the spectra with certain elemental composition.
#For measurements of the continental or urban background aerosol the assumptions behind this procedure are typically well met and the AMS provides robust quantitative information on the sub-micron aerosol composition. 
#However, under certain conditions, e.g., when measuring close to anthropogenic sources or in the marine environment, the limitations of these assumptions are sometimes reached and the standard analysis could result in misinterpretation of the mass spectra.
#The method can be performed online (sampling ambient air) or offline (through injection). 
#It is assumed unless otherwise stated that instrumental sampling is done via injection.

#gravimetry (GR)

#An air pump draws ambient air at a constant flow rate into a specially shaped inlet where particulate matter is separated into size fractions. 
#Particulate matter is then collected on a filter. Each filter is weighed before and after use, to determine the net mass gain due to collected matter. 
#The total volume of air filtered is known from the constant air flow, and the difference in filter weights is used to calculate the particulate matter concentration in micrograms per cubic meter (μg/m3) of air.

#Known Interference:
#Particulate matter may be lost during filter handling and weighing procedures, especially if filter is exposed to warming.
#Gaseous species may contaminate filters.
#Humidity and absorbed water may be difficult to control both during operations and when handling filters.
#Removing filters and transporting to a lab for analysis may affect results. 
#Meteorological conditions may affect flow rate.

#tapered element oscillating microbalance - gravimetry (TEOM-GR)

#The TEOM - Gravimetric method essentially involves a true “gravimetric” instrument that draws (then heats) ambient air through a filter at constant flow rate, continuously weighing the filter and calculating near real-time mass concentrations of particulate matter.
#The TEOM uses a hollow glass tube as a microbalance. Incoming particles are deposited on a filter at the tip of the tube, and the added mass causes a change in its oscillation frequency which is detected electronically. 
#The element is periodically cycled to return it to its natural frequency. TEOM devices operate continuously and do not need filter changes as frequently as high-volume air samplers.

#Typical operation:
#1. Air is drawn through a tapered glass element with a filter attached. 
#2. The element oscillates according to a characteristic frequency, that decreases as mass accumulates on the attached filter. 
#3. Measurement of the change in frequency converts to measurement of the accumulated mass.

#tapered element oscillating microbalance - filter dynamics measurement system - gravimetry (TEOM-FDMS-GR)

#The Filter Dynamics Measurement System (FDMS) is a hybrid of the TEOM system which is able to measure the semi-volatile fraction of airborne particulate matter. 
#This can be important in the study of primary and secondary PM and to ensure there are no losses of these semi volatile fractions due to sampling conditions. 
#TEOM instruments with FDMS alternate between a base cycle and a reference cycle, the latter of which measures the mass loss of the filter when clean air is passed through it, allowing the mass loss during the base cycle to be estimated.
#It is important that the air conditioning system not cycle over the same period as the TEOM instrument, because this can cause aliasing.

#pressure drop tape sampling (PDTS)

#Pressure drop tape sampling measures particles by monitoring the pressure drop across a porous membrane filter (fluoropore).
#The method was originally developed at Harvard University (Babich et al., 1997).
#The pressure drop is linearly correlated to the particle mass deposited on the filter.
#The filter face veolocity is chosen such that pore obstruction by interception is the dominant cause of particle related pressure drop change over time.
#The monitor exposes a new segment of filter tape every 20-60 minutes for particle collection.

#beta-attenuation (BA)

#Beta particles (electrons with energies in the 0.01 to 0.1 MeV range) are attenuated according to an approximate exponential function when they pass through particulate deposits on a filter tape. 
#Automated samplers (analyzers) use a continuous filter tape, first measuring the attenuation by the unexposed tape, and then measuring the attenuation after the tape has passed through the ambient air flow. 
#The attenuation measurement converts to a measure of the mass on the filter, so that the filters do not require later laboratory analysis for the mass variable. For some devices, the beta particle source is 14C.

#Known Interference:
#Particulate matter may be lost due to filter tape advance and vibration, especially if filter is exposed to warming.
#Gaseous species may contaminate filters.
#Humidity and absorbed water may be difficult to control during operations. 
#Meteorological conditions may affect flow rate.
#Although on-site real-time mass measurement offers significant improvements over the filter removal and laboratory analysis process, the beta emission and detection process present additional on-site maintenance requirements.

#nephelometry (NP)

#Nephelometry is based on the bulk scattering of visible light by an air sample. It is a mature technology and provides reliable measurements of the spectral (aerosol) scattering coefficient of the air (unit Mm‐1).
#An integrating nephelometer combines the light from all scattering angles to produce a spectral scattering coefficient for the wavelength of light used.
#The signal obtained by integrating nephelometer measurements is closely proportional to the cosine weighted scattering function, which is equal to the scattering part of the Lambert‐Beer extinction coefficient.
#The scattering coefficient is not linearly proportional to aerosol mass concentration, but a more complex function of aerosol composition, shape, density, size distribution, and index of refraction. 
#Thus to convert the scattering coefficient to a mass concentration, assumptions are needed to be made regarding the type of aerosol present, and environmental factors (k-factors).
#K-factors are typically determined by the user by running the nephelometer next to an air sampling pump and comparing results.
#The correction factors necessary may have a significant seasonal and spatial variability (Chow et al. 2006); hence nephelometry is best suited in environments with a rather stable aerosol composition.

#light scattering photometry (LSP)
        
#Light scattering photometers do not integrate the light from all scattered angles, but only view a portion of the available scattering angles. 
#Like nephelometry, it produces a bulk scattering coefficient of an air sample with similar time resolution and range. 
#In general they are calibrated with a standard test aerosol such as Arizona Test Dust, but typically these test aerosols have significantly different optical properties from real ambient air aerosols.
#Again, therefore, assumptions about the type of aerosol present, and environmental factors, are needed to convert the scattering coefficient to a mass concentration, and uncertainties tend to be higher than for nephelometers.
#See here for distinction between nephelometry and light scattering photometry: https://db-airmontech.jrc.ec.europa.eu/download/PM_Mass_MMTI_OpticalDevices.pdf

#optical particle counter (OPC)

#Optical particle counters differ from nephelometry and light scattering photometry in being based on measuring the light scattered by individual particles. 
#The light scattered by individual particles is picked up as (typically) a discrete signal, so that the size of each particle can be gauged from the intensity of the signal, while the number concentration of particles can be gauged from the number of signals and the air flow rate through the light beam volume. 
#In general, therefore, a size spectrum of particles will be obtained, so that information about specific size fractions, such as PM10 and PM2.5, can be obtained simultaneously. 
#These can then be converted to mass concentrations by making assumptions about the particle density.
#Uncertainties arise from the determination of the size of the volume of air being examined by the laser, scattering from more than one particle at the same time (coincidence), and the conversions from intensity to size and then to mass. 
#Nevertheless, performance can be comparable with other automatic methods for PM10 and PM2.5.

#differential mobility particle sizer (DMPS)

#Optical techniques are limited in being unable to detect particles smaller than 50-100nm, and are also susceptible to sizing errors resulting from variations in particle shape and refractive index. 
#Differential mobility techniques are able to measure much smaller particles, down to 2.5nm and are not sensitive to differences in refractive index, but are not able to achieve the same temporal resolution as optical instruments, and are also sensitive to variations in particle shape.
#The Differential Mobility Particle Sizer couples a differential mobility analyzer (DMA), which classifies charged particles according to their mobility in an electric field, and a condensation particle counter (CPC) to count particles of a specific mobility. 
#In the atmosphere most aerosol are charged, often with multiple elementary charges, in order for classification by electrical mobility to be meaningful in terms of particle size, the aerosol must be given a known charge distribution. 
#This is done by exposing the particles to a stream of beta radiation, resulting in a charge distribution known as a Fuchs distribution. 
#This distribution has known fractions of the aerosol population which are singly, doubly and triply charged etc. 
#When viewing the output from a DMA set to select a single electrical mobility with an optical particle counter, multiply charged peaks can clearly be seen. 
#Clearly when performing a scan, the presence of multiply charged particles has the potential to affect the results. 
#This is generally dealt with by physically limiting the maximum particle size which may enter the DMA (this is usually done with an impactor) to just above the maximum size which is to be scanned. 
#Thus there can be no multiply charged particles present in the largest size bins. In turn multiply charged particles may be removed from smaller size bins based on the known charge distribution and the measured number concentration of these larger particles.

#scanning mobility particle sizer (SMPS)

#The Scanning Mobility Particle Sizer is based on the principal of the mobility of a charged particle in an electric field. 
#Particles entering the system are neutralized (using a radioactive source) such that they have a Fuchs equilibrium charge distribution. 
#They then enter a Differential Mobility Analyser (DMA) where the aerosol is classified according to electrical mobility, with only particles of a narrow range of mobility exiting through the output slit. 
#This monodisperse distribution then goes to a Condensation Particle Counter which determines the particle concentration at that size. 
#The DMA consists of a cylinder, with a negatively charged rod at the center, the main flow through the DMA is particle free 'sheath' air. 
#It is important that this flow is laminar. The particle flow is injected at the outside edge of the DMA, particles with a positive charge move accross the sheath flow towards the central rod, at a rate determined by their electrical mobility. 
#Particles of a given mobility exit through the sample slit at the top of the DMA, while all other particles exit with the exhaust flow. The size of particle exiting through the slit being determined by the particles size, charge, central rod voltage, and flow within the DMA. 
#By (in the case of the SMPS) exponentially scanning the voltage on the central rod, a full particle size distribution is built up. 
#SMPS is a variation of DMPS, with some advantages. A major advantage is it’s ease of portability and significantly lower power consumption. It also can produce aerosol spectra with a much higher temporal resolution, though the sampling statistics suffer especially if fast scans are carried out under clean ambient conditions.

#thermal analysis (TA)

#Thermal analysis (TA) differentiates between organic carbon (OC) and light-absorbing carbon (LAC) by oxidising collected samples to CO2 at an intermediate temperature and at a high final burn temperature. 
#Because thermal analysis does not yield a true value of LAC, the refractory component it measures takes a different name: elemental carbon (EC). (This has no relationship to a chemist’s definition of “elemental.”) 
#Thermal methods rely on the assumption that organic carbon is volatile, and the strongly light absorbing carbon is stable or refractory at elevated temperatures. 
#It assumes that LAC in a sample is unchanged until exposed to both elevated temperatures and an oxidant, so that carbon driven off at low temperatures or in the absence of oxygen must be OC. 
#The method physically determines OC, EC and total carbon (TC) by measurement of CO2 by infrared detection.
#By heating in stages it is possible to attribute carbon broken down at lower temperatures to OC, and those at higher temperatures to EC.
#Ideally, TA would be a separation-and-detection technique similar to chromatography, but failures of separation have hampered its interpretation.
#Some OC undergoes pyrolysis or charring in the absence of oxygen, forming pyrolyzed carbon (“charring”) instead of volatilizing (Huntzicker et al., 1982). 
#TA applies no correction for this.

#thermal-optical analysis - unknown protocol (TOA-UNK)

#Thermal-optical analysis (TOA) is the most widely used method to measure organic and elemental carbon in the scientific community. 
#It uses the same principals as thermal analysis but builds upon them by using laser monitoring to correct for the transformation of non-absorbing carbon into pyrolytic carbon that absorbs light.
#Additionally, samples are oxidised at various steps on a temperature ramp (rather than just 2), to provide more information for OC/EC split.
#The sample usually becomes blacker as charring occurs in an inert atmosphere, and the blackness decreases as the pyrolyzed carbon burns later in the analysis. 
#This change is detected by monitoring either transmittance or reflectance (sometimes both). When the filter’s transmittance or reflectance returns to the original value, it is assumed that the remaining material is EC. 
#This point is colloquially termed the OC/EC split.
#There have been wide discourse regarding the OC/EC split definition, with different protocols having their own temperature ramps and step durations.  
#There are currently 3 well established protocols for the handling of the apportionment between EC and OC:
# NIOSH 5040 
# IMPROVE-A 
# EUSAAR2 

#TOA instruments can be operated following any of these protocols, therefore for clarity, a separate method is given referencing each of these these protocols

#aethalometer (ATH)

#The aethalometer is an instrument designed for the measurement of black carbon deposit collected continuously deposited on quartz fiber filter (designed by Magee Scientific).
#The 'aethalometer' is the dominant market instrument (designed by Magee Scientific), of which there are multiple versions. 
#It measures the concentration of optically absorbing (‘black’) suspended particulates in a gas colloid stream; commonly visualised as smoke or haze, often seen in ambient air under polluted conditions. 
#The word aethalometer is derived from the Classical Greek verb ‘aethaloun’, meaning ‘to blacken with soot’.
#The gas stream (frequently ambient air) passes through a filter material which traps the suspended particulates, creating a deposit of increasing density. 
#A light beam projected through the deposit is attenuated by those particles which are absorbing (‘black’) rather than scattering (‘white’).
#Measurements are made at successive regular time intervals. The increase in attenuation from one measurement to the next is proportional to the increase in the density of optically absorbing material on the filter: which, in turn, is proportional to the concentration of the material in the sampled air stream. 
#The sample is collected as a spot on a roll of filter tape. 
#When the density of the deposit spot reaches a pre-set limit, the tape advances to a fresh spot and the measurements continue. 
#Measurement of the sample gas flow rate and knowledge of the instrument’s optical and mechanical characteristics permit a calculation of the average concentration of absorbing particles in the gas stream during the sampling period. 
#Aethalometers may operate on time-base periods as rapid as 1 second, providing quasi-real-time data. Comparison of aethalometer data with other physical and chemical analyses allows the output to be expressed as a concentration of black carbon.

#multi angle absorption photometer (MAAP)

#The MAAP instrument (introduced with the Thermo-Scientific model 5012) was specifically developed to reduce the uncertainties in black carbon measurements caused by aerosol scattering.
#The MAAP measures black carbon mass loadings based on aerosol optical absorption. In common with the Aethalometer this measurement is made on particles collected on a filter substrate, however there are some important differences in how the instruments operate, as well as with the algorithms used to extract the absorption coefficient and mass loading.
#With the MAAP the optical absorption coefficient of aerosol collected on a filter is determined by radiative transfer considerations which include multiple scattering effects and absorption enhancement due to reflections from the filter. 
#This calculation is based on the transmitted and reflected phase functions which are defined by directly measured values of transmission, direct and diffuse back scattering. 
#Full details of the algorithms used are given by Petzold et al (2002 and 2004). 
#Lab work showed that the diffuse back scatter component was a strong function of the fraction of scattering aerosol, being decreased (relative to the filter) for low scattering fractions and increased for high scattering fractions. 
#This lab work also informed the choice of angles for the detectors used.

#particulate soot absorption photometer (PSAP)

#The PSAP instrument (manufactured by Radiance Research Inc.) measures the change in optical transmission of a filter as aerosol is deposited on the filter over time.
#The PSAP measures black carbon mass loadings based on aerosol optical absorption. In common with the Aethalometer this measurement is made on particles collected on a filter substrate, however there are some important differences in how the instruments operate, as well as with the algorithms used to extract the absorption coefficient and mass loading.
#There are currently 2 instrument types, 1 measuring at 1 wavelength (525nm), and one at 3 wavelengths (467, 530 and 660nm). 
#The change in transmission from one measurement to the next is related to the optical absorption coefficient (bap m-1) of the aerosol deposited in this time. 
#In turn this can be related to black carbon mass by dividing by the specific absorption for black carbon at the wavelength of the instrument. 
#Comparisons between the PSAP aerosol optical absorption measurement and reference techniques presented by Bond et al (1999), show that the PSAP also responds to pure scattering particles and external mixtures of scattering and absorbing particles. 
#This is because back scatter from scattering particles on the filter reduces the transmitted intensity. Bond et al show that the apparent absorption coefficient of purely scattering particles as measured by the PSAP is about 2% of their scattering coefficient. 
#Additionally even when the PSAP measurement is corrected for errors in flow rate, collection spot area and the presence of scattering particles, the same series of experiments showed that PSAP optical absorption coefficients were about 20% higher than the reference measurement for the type of aerosol used. 
#Thus PSAP data must be carefully calibrated and corrected based on measurements of aerosol scattering coefficient.

#continuous light absorption photometer (CLAP)

#The Continuous Light Absorption Photometer (CLAP) is a NOAA/GMD developed, filter-based method that measures light absorption by particles at three wavelengths (467, 528, 652 nm). 
#The CLAP is functionally comparable to a widely-used commercial instrument, the Particle/Soot Absorption Photometer (PSAP), but does not suffer from the same operating limitations as the PSAP (data loss from overloaded filters, unheated optics block, internal black box processing of data). 
#The choice of a functionally comparable design to the PSAP allowed measurements from the CLAP to use the well-established PSAP correction schemes that account for known imperfections in all filter-based absorption measurements. 
#Ogren et al. (2017) describes the design, operation and uncertainties of the CLAP and presents comparisons with the PSAP at several NFAN sites.
#The primary advantages of the CLAP, compared to the PSAP, are that it is one-tenth the size, can sample for roughly eight times as long before the operator needs to change the filter, and is temperature-stabilized to reduce sensitivity to changes in room temperature. 
#In addition, the computer software running on the internal microprocessor is completely open on the CLAP. These features make the CLAP much better suited for long-term monitoring applications, and currently NOAA-built CLAPs are deployed at 23 stations around the globe.
#During the initial field deployment of the NOAA-built CLAPs, they were run in parallel with PSAPs for over a year at multiple stations to confirm that the CLAPs and PSAPs give comparable results. Subsequently, NOAA has retired the PSAPs from service at its monitoring stations.

#flame atomic absorption spectroscopy (F-AAS)

#Atomic absorption spectroscopy (AAS) detects elements in either liquid or solid samples through the application of characteristic wavelengths of electromagnetic radiation from a light source. 
#Individual elements will absorb wavelengths differently, and these absorbances are measured against standards. In effect, AAS takes advantage of the different radiation wavelengths that are absorbed by different atoms.
#In AAS, analytes are first atomized so that their characteristic wavelengths are emitted and recorded. Then, during excitation, electrons move up one energy level in their respective atoms when those atoms absorb a specific energy.
#As electrons return to their original energy state, they emit energy in the form of light. 
#This light has a wavelength that is characteristic of the element. Depending on the light wavelenth and its intensity, specific elements can be detected and their concentrations measured.
#Applying the Beer-Lambert law directly in AA spectroscopy is difficult due to variations in the atomization efficiency from the sample matrix, and nonuniformity of concentration and path length of analyte atoms.
#Flame atomic absorption spectrometry (F-AAS) is where the sample is first atomised using flames, principally a air-acetylene flame with a temperature of about 2300 °C and a nitrous oxide system (N2O)-acetylene flame with a temperature of about 2700 °C. 
#The latter flame, in addition, offers a more reducing environment, being ideally suited for analytes with high affinity to oxygen.
#Liquid or dissolved samples are typically used with flame atomizers. 
#The sample solution is aspirated by a pneumatic analytical nebulizer, transformed into an aerosol, which is introduced into a spray chamber, where it is mixed with the flame gases and conditioned in a way that only the finest aerosol droplets (< 10 μm) enter the flame. 
#This conditioning process is responsible that only about 5% of the aspirated sample solution reaches the flame, but it also guarantees a relatively high freedom from interference.

#graphite furnace atomic absorption spectroscopy (GF-AAS)

#Graphite furnace atomic absorption spectroscopy (GF-AAS) (also known as Electrothermal Atomic Absorption Spectroscopy (ET-AAS)) is a type of spectrometry that uses a graphite-coated furnace to vaporize the sample. 
#In GF-AAS, samples are deposited in a small graphite or pyrolytic carbon coated graphite tube, which can then be heated to vaporize and atomize the analyte. 
#The main advantages of the graphite furnace comparing to flame atomic absorption are the following:
#-The detection limits for the graphite furnace fall in the ppb range for most elements
#-Interference problems are minimized with the development of improved instrumentation
#-The graphite furnace can determine most elements measurable by flame atomic absorption in a wide variety of matrices.

#cold vapour atomic absorption spectroscopy (CV-AAS)

#Cold vapour atomic absorption spectroscopy (CV-AAS) is a method limited to the determination of mercury, due to it being the only metallic element to have a large enough vapor pressure at ambient temperature. 
#Because of this, it has an important use in determining organic mercury compounds in samples and their distribution in the environment. 
#The method initiates by converting mercury into Hg2+ by oxidation from nitric and sulfuric acids, followed by a reduction of Hg2+ with tin(II) chloride. 
#The mercury, is then swept into a long-pass absorption tube by bubbling a stream of inert gas through the reaction mixture. 
#The concentration is determined by measuring the absorbance of this gas at 253.7 nm. Detection limits for this technique are in the parts-per-billion range making it an excellent mercury detection atomization method.
#See here for determination of Cd using this method also: https://www.ncbi.nlm.nih.gov/pubmed/19071344

#hydride generation atomic absorption spectroscopy (HG-AAS)

#The hydride generation atomic absorption spectroscopy (HG-AAS) method is specialised for the measurement of specific elements. 
#The technique provides a means of introducing samples containing arsenic, antimony, selenium, bismuth, and lead into an atomizer in the gas phase. 
#With these elements, hydride atomization enhances detection limits by a factor of 10 to 100 compared to alternative methods. 
#Hydride generation occurs by adding an acidified aqueous solution of the sample to a 1% aqueous solution of sodium borohydride, all of which is contained in a glass vessel. 
#The volatile hydride generated by the reaction that occurs is swept into the atomization chamber by an inert gas, where it undergoes decomposition. 
#This process forms an atomized form of the analyte, which can then be measured by absorption or emission spectrometry.
#See more information here: https://www.sciencedirect.com/topics/chemistry/hydride-generation

#flame atomic emission spectroscopy (F-AES)

#Atomic emission spectroscopy (AES) is a method of chemical analysis that uses the intensity of light emitted from a flame, plasma, arc, or spark at a particular wavelength to determine the quantity of an element in a sample. 
#The wavelength of the atomic spectral line gives the identity of the element while the intensity of the emitted light is proportional to the number of atoms of the element.

#AAS and AES are similar methods but the differences are as follows:
#-Light Source: In AAS, a monochromatic light source is used to provide energy for the excitation of electrons. In the case of AES, it is a flame that is often used.
#-Atomization: In AAS, there is a separate chamber for atomization of the sample. However, in AES, atomization takes place step by step upon the introduction of the sample to the flame.
#-Principle of operation: In AAS, when monochromatic light is bombarded through the sample the atoms absorb energy, and the extent of absorption is recorded. In AES, the sample which gets atomised in the flame then absorbs the energy through the electrons which get excited. Later this energy is released upon the relaxation of the atoms and is measured by the instrument as the emitted energy.

#In flame atomic emission spectroscopy (F-AES) a sample of a material (analyte) is brought into the flame as a gas, sprayed solution, or directly inserted into the flame by use of a small loop of wire, usually platinum. 
#The heat from the flame evaporates the solvent and breaks chemical bonds to create free atoms. The thermal energy also excites the atoms into excited electronic states that subsequently emit light when they return to the ground electronic state. 
#Each element emits light at a characteristic wavelength, which is dispersed by a grating or prism and detected in the spectrometer.

#cold vapour atomic fluorescence spectroscopy (CV-AFS)

#Cold vapour atomic fluorescence spectroscopy (CV-AFS) is a subset of the analytical technique known as atomic fluorescence spectroscopy (AFS).
#Used in the measurement of trace amounts of volatile heavy metals such as mercury, cold vapour AFS makes use of the unique characteristic of mercury that allows vapour measurement at room temperature. 
#Free mercury atoms in a carrier gas are excited by a collimated ultraviolet light source at a wavelength of 253.7 nanometres. 
#The excited atoms re-radiate their absorbed energy (fluoresce) at this same wavelength. Unlike the directional excitation source, the fluorescence is omnidirectional and may thus be detected using a photomultiplier tube or UV photodiode.
#Gold coated traps may be used to collect mercury in ambient air or other media. 
#The traps are then heated, releasing the mercury from the gold while passing argon through the cartridge. 
#This preconcentrates the mercury, increasing sensitivity, and also transfers the mercury into an inert gas.
#See more information for measurement of Hg here: https://ec.europa.eu/environment/air/pdf/pp_mercury4.pdf

#inductively coupled plasma mass spectrometry (ICP-MS)

#Inductively coupled plasma mass spectrometry (ICP-MS) is a type of mass spectrometry which is capable of detecting metals and several non-metals at concentrations as low as one part per quadrillion on non-interfered low-background isotopes. 
#This is achieved by ionizing the sample with inductively coupled plasma and then using a mass spectrometer to separate and quantify those ions.
#Compared to atomic absorption spectroscopy, ICP-MS has greater speed, precision, and sensitivity. 
#However, compared with other types of mass spectrometry, such as thermal ionization mass spectrometry (TIMS) and glow discharge mass spectrometry (GD-MS), ICP-MS introduces many interfering species: argon from the plasma, component gases of air that leak through the cone orifices, and contamination from glassware and the cones.

#X-ray fluorescence spectroscopy (XRFS)

#X-Ray Fluorescence Spectroscopy (XRFS) is an analytical technique that uses the interaction of x-rays with a material to determine its elemental composition. XRF is suitable for solids, liquids and powders, and in most circumstances is non-destructive.
#There are two main XRF methodologies - energy dispersive (EDXRF) and wavelength dispersive (WDXRF). Each method has its own advantages and disadvantages.
#The sample is irradiated with x-rays which causes the emission of fluorescent x-rays to emerge from the sample.
#The range of detectable elements varies according to instrument configuration and set up, but typically EDXRF covers all elements from sodium (Na) to uranium (U), whilst WDXRF can extend this down to beryllium (Be). Concentrations can range from 100% down to ppm and in some cases sub-ppm levels. 
#Limits of detection depend upon the specific element and the sample matrix, but as a general rule, heavier elements will have better detection limits.
#The key components of a typical XRF spectrometer are: 1. Source of X-Rays used to irradiate the sample. 2. Sample. 3. Detection of the emitted fluorescent X-Rays. 4. The resulting XRF spectrum shows intensity of X-Rays (usually in counts per second) as a function of energy (usually in eV).

#particle induced X-ray emission (PIXE)

#particle induced X-ray emission is a powerful and relatively simple analytical technique that can be used to identify and quantify trace elements typically ranging from Al to U. 
#After high energy ion bombardment, X-rays are emitted which can be measured.
#Sample irradiation is usually performed by means of protons or alpha particles produced by an accelerator.
#X-ray detection is usually done by energy dispersive semiconductor detectors such as Si(Li) or High Purity Germanium detectors. 
#Varies from X-ray fluorescence spectroscopy as x-ray emission is induced by a particle, not X-rays.

#photometry - direct (P-D)

#remote photometry involves measurements of spectral sun/moon irradiance (direct) and sky radiances (sky) 
#sun photometry is a passive remote-sensing measurement technique in which mainly collimated light generally not scattered or absorbed by the atmosphere illuminates a photodiode detector and this light energy is converted to a digital signal. 
#The digital signal (V) measured by the instrument is proportional to the solar irradiance.
#A sensor head fitted with 25 cm collimators is attached to a 40 cm robot base which systematically points the sensor head at the Sun, the sky and the moon according to a preprogrammed routine.
#The measurements are made in eight spectral bands requiring approximately 10 seconds. 
#Eight interference filters at wavelengths of 340, 380, 440, 500, 670, 870, 940 and 1020 nm are located in a filter wheel which is rotated by a direct drive stepping motor. 
#The 940 nm channel is used for column water abundance determination. A preprogrammed sequence of measurements is taken by these instruments starting at an air mass of 7 in the morning and ending at an air mass of 7 in the evening.
#Optical depth is calculated from spectral extinction of direct beam radiation at each wavelength based on the Beer-Bouguer Law. Attenuation due to Rayleigh scatter, and absorption by ozone, and gaseous pollutants is estimated and removed to isolate the aerosol optical depth (AOD). 
#A sequence of three such measurements are taken 30 seconds apart creating a triplet observation per wavelength.
#During the large air mass periods direct sun measurements are made at 0.25 air mass intervals, while at smaller air masses the interval between measurements is typically 15 minutes. 
#The time variation of clouds is usually greater than that of aerosols causing an observable variation in the triplets that can be used to screen clouds in many cases. 
#Additionally the 15-minute interval allows a longer temporal frequency check for cloud contamination.

#The latest models can also perform nighttime measurements of the spectral lunar irradiance.

#photometry - sky (P-S)

#In addition to the direct solar irradiance measurements remote photometric instruments makes with a field of view of 1.2 degrees, these instruments measure the sky radiance in four spectral bands (440, 670, 870 and 1020 nm) along the solar principal plane (i.e., at constant azimuth angle, with varied scattering angles) up to nine times a day and along the solar almucantar (i.e., at constant elevation angle, with varied azimuth angles) up to six times a day. 
#The approach is to acquire aureole and sky radiances observations through a large range of scattering angles from the sun through a constant aerosol profile to retrieve size distribution, phase function and aerosol optical depth. 
#More than eight almucantar sequences are made daily at an optical air mass of 4, 3, 2 and 1.7 both morning and afternoon. Sky radiance measurements are inverted with the Dubovik and Nakajima inversions to provide aerosol properties of size distribution and phase function over the particle size range of 0.1 to 5 um.
#The robot mounted sensor head is parked pointed near-nadir when idle to prevent contamination of the optical windows from rain and foreign particles.
