Stationary source emissions — Determination of the mass concentration of individual volatile organic compounds (VOCs) in waste gases from non-combustion processes
Preview
Summary
This document specifies the use of FTIR spectrometry for determining the concentrations of individual
volatile organic compounds (VOCs) in waste gases from non-combustion processes. The method can
be employed to continuously analyse sample gas which is extracted from ducts and other sources. A
bag sampling method can also be applied, if the compounds do not adsorb on the bag material, and is
appropriate in cases where it is difficult or impossible to obtain a direct extractive sample.
The principle, sampling procedure, IR spectral measurement and analysis, calibration, handling
interference, QA/QC procedures and some essential performance criteria for measurement of individual
VOCs are described in this document.
NOTE 1 The practical minimum detectable concentration of this method depends on the FTIR instrument (i.e.
gas cell path length, resolution, instrumental noise and analytical algorithm) used, compounds, and interference
specific (e.g. water and CO2
).
