Standard Test Method for Determination of Gaseous Compounds by Extractive Direct Interface Fourier Transform Infrared (FTIR) Spectroscopy

Importancia y uso:

5.1 The FTIR measurements provide for multicomponent on-site analysis of source effluent.

5.2 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.

5.3 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.

5.4 The FTIR measurement data are used to evaluate process conditions, emissions control devices, and for determining compliance with emission standards or other applicable permits.

5.5 Data quality objectives for each specific testing program must be specified and outlined in a test plan (Annex A1).5
