Infrared Gas Analyzer (IRGA) CO2 measurement by integration method
In use from 2020-10-01
This method uses continuous measurements (every second) from the Infrared Gas Analyzer (IRGA) unit to measure the CO2 concentration of a gas sample. The method described here only details the use of a python script to convert the raw continuous data into discrete sample-by- sample integrations. When used in conjunction with the appropriate standards these integrals can give you the concentration of CO2 in the sample that you injected. The output is an excel spreadsheet with each sample’s integrated CO2 value and the time at which it was taken. This output can then be copied into your sample spreadsheet.
