Chinese:固定污染源废气 气态污染物(SO2、NO、NO2、CO、CO2)的测定 便携式傅立叶变换红外光谱法
English:Determination of gaseous pollutants (SO2, NO, NO2, CO, CO2) in exhaust gases from stationary sources Portable Fourier Transform Infrared Spectroscopy
Effective Date:2022-06-01
Standard Applicability:This standard specifies the determination of gaseous pollutants (SO2, NO, NO2, CO, CO2) in the exhaust gas of stationary sources of pollution portable Fourier transform infrared spectrometry. This standard applies to the determination of gaseous pollutants (SO2, NO, NO2, CO, CO2) in the exhaust gas from stationary sources. The method detection limit of SO2, NO, CO is 1 mg/m3, and the lower limit of determination is 4 mg/m3; the method detection limit of NO2 is 3 mg/m3, and the lower limit of determination is 12 mg/m3; the method detection limit of CO2 is 1 g/m3, and the lower limit of determination is 4 g/m3.
