Scope

This standard specifies the portable Fourier transform infrared spectrometry method for measuring gaseous pollutants (SO2, NO, NO2, CO, CO2) in waste gas from fixed pollution sources. This standard is applicable to the measurement of gaseous pollutants (SO2, NO, NO2, CO, CO2) in waste gas from fixed pollution sources. The detection limits of SO2, NO, and CO are all 1 mg/m3, and the measurement lower limits are all 4 mg/m3; the detection limit of NO2 is 3 mg/m3, and the measurement lower limit is 12 mg/m3; the detection limit of CO2 is 1 g/m3, and the measurement lower limit is 4 g/m3.
