Significance and Use
The FTIR measurements provide for multicomponent on-site analysis of source effluent.
This test method provides the volume concentration of detected analytes. Converting the volume concentration to a mass emission rate using a particular compound's molecular weight, and the effluent volumetric flow rate, temperature and pressure is useful for determining the impact of that compound to the atmosphere.
Known concentrations of target analytes are spiked into the effluent to evaluate the sampling and analytical system's effectiveness for transport and quantification of the target analytes, and to ensure that the data collected are meaningful.
The FTIR measurement data are used to evaluate process conditions, emissions control devices, and for determining compliance with emission standards or other applicable permits.
Data quality objectives for each specific testing program must be specified and outlined in a test plan (Annex A1). Supporting data are available from ASTM Headquarters Request RR:D22-1027.
Scope
1.1 This field test method employs an extractive sampling system to direct stationary source effluent to an FTIR spectrometer for the identification and quantification of gaseous compounds. This test method is potentially applicable for the determination of compounds that (1) have sufficient vapor pressure to be transported to the FTIR spectrometer and (2) absorb a sufficient amount of infrared radiation to be detected.
1.2 This field test method provides near real time analysis of extracted gas samples from stationary sources. Gas streams with high moisture content may require conditioning to minimize the excessive spectral absorption features imposed by water vapor.
