 For the purpose of standardising the measurement methods, a database containing all the possible measuring instruments by measurement method has been constructed.
 
-Almost all measuring instruments come with an instrumental manual written by the instrument manufacturer that gives information pertaining to the quality of the measuring instrument in measuring specific parameters. These manuals give information such as lower/upper limits of detection, flow rates, precision, accuracy, zero drift, etc. All of this information is captured in standardised variables, named with a preceding ‘documented_’ string.

 This ‘documented’ information however is just applicable for the out of the box, measurement experts in the lab may have optimised the measurement methodology to provide better (or worse!) limits of detections, etc… They sometimes give this information enclosed with the reported data. This ‘documented’ information can therefore be thought as template information, with updated more accurate information provided by the data reporters. All of this reported information is captured in standardised variables, named with a preceding `reported_` string.

 The standardisations here therefore needs to be general enough to capture information pertaining to multiple stages of measurement procedures. Therefore all information is separated out between 3 distinct categories: **Primary Sampling**, **Sample Preparation** and **Measurement**. 
 
-The primary sampling category exists for cases when the sampling is separate from the measuring instrument/method, for example, low volume samplers which filter for specifically-sized aerosols and then are measured by manual gravimetry. Information regarding primary sampling instruments is maintained separately to that for measuring instruments.
