Three new national standards will be introduced, which are related to fixed source exhaust gas monitoring

Recently, the Ministry of Ecology and Environment issued the "Portable Fourier Transform Infrared Spectroscopy for the Determination of Ammonia and Hydrogen Chloride in Waste Gas from Fixed Pollution Sources" Draft for soliciting opinions on three national ecological and environmental standards, including the "Portable Catalytic Oxidation Hydrogen Flame Ionization Detector Method for the Determination of Total Hydrocarbons, Methane, and Non methane Total Hydrocarbons in Waste Gas from Fixed Pollution Sources" and the "Portable Gas Chromatography Hydrogen Flame Ionization Detector Method for the Determination of Total Hydrocarbons, Methane, and Non methane Total Hydrocarbons in Waste Gas from Fixed Pollution Sources".

01
Determination of ammonia and hydrogen chloride in exhaust gas from fixed pollution sources - Portable Fourier transform infrared spectroscopy (draft for comments)

Applicable scope

This standard specifies a portable Fourier transform infrared spectroscopy method for the determination of NH3 and HCl in exhaust gas from fixed pollution sources.
This standard is applicable to the determination of NH3 and HCl in organized exhaust emissions from fixed pollution sources.
Method detection limit: NH3 is 1mg/m3, HCl is 1mg/m3.
Lower limit of determination: NH3 is 4mg/m3, and HCl is 4mg/m3.

02
Determination of Total Hydrocarbons, Methane, and Non methane Total Hydrocarbons in Waste Gas from Fixed Pollution Sources - Portable Catalytic Oxidation Hydrogen Flame Ionization Detector Method (Draft for Solicitation of Comments)

Applicable scope

This standard specifies the portable catalytic oxidation hydrogen flame ionization detector method for the determination of total hydrocarbons, methane, and non methane total hydrocarbons in organized exhaust emissions from fixed pollution sources.
This standard is applicable to the determination of total hydrocarbons, methane, and non methane total hydrocarbons in organized exhaust emissions from fixed pollution sources.
This standard stipulates that the detection limit for total hydrocarbons is 0.3mg/m3 (measured by methane), and the lower limit for determination is 1.2mg/m3 (measured by methane); The detection limit of methane is 0.4mg/m3 (based on methane), and the lower limit of determination is 1.6mg/m3 (based on methane); The detection limit for non methane total hydrocarbons is 0.3mg/m3 (measured by carbon), and the lower limit for determination is 1.2mg/m3 (measured by carbon).

03
Determination of Total Hydrocarbons, Methane, and Non methane Total Hydrocarbons in Waste Gas from Fixed Pollution Sources - Portable Gas Chromatography Hydrogen Flame Ionization Detector Method (Draft for Solicitation of Comments)

Applicable scope

This standard specifies the portable gas chromatography-hydrogen flame ionization detector method for the determination of total hydrocarbons, methane, and non methane total hydrocarbons in exhaust gas from fixed pollution sources.
This standard is applicable to the determination of total hydrocarbons, methane, and non methane total hydrocarbons in organized exhaust emissions from fixed pollution sources.
This method determines the detection limits of total hydrocarbons and methane in the organized emission of waste gas from fixed pollution sources, with a detection limit of 0.2mg/m (calculated by methane) and a detection limit of 0.8mg/m3 (calculated by methane). The detection limit of non methane total hydrocarbons is 0.2mg/m3 (calculated by carbon) and a detection limit of 0.8mg/m3 (calculated by carbon).
