HJ 38-2017 Stationary pollution source waste gas - Determination of methane
HJ 38-2017 Determination of Methane in Waste Gas from Stationary Pollution Sources Details:

Methane capillary column:

Stationary phase: Porous layer open tube molecular sieve column or other equivalent capillary column

Specifications: 30m*0.53mm*25um

Application: HJ 38-2017 Waste gas from stationary pollution sources-Determination of total hydrocarbons, methane and non-methane total hydrocarbons-Gas chromatography



This standard specifies the gas chromatography method for the determination of total hydrocarbons, methane and non-methane total hydrocarbons in waste gas from stationary pollution sources.

       This standard is applicable to the determination of total hydrocarbons, methane and non-methane total hydrocarbons in the waste gas of fixed pollution sources.

When the injection volume is 1.0 ml, the detection limit of this method for the determination of total hydrocarbons and methane is 0.06 mg/m3 (calculated as methane), and the lower detection limit is 0.24 mg/m3 (calculated as methane); non-methane total hydrocarbons The detection limit is 0.07mg/m3 (calculated by carbon), and the lower limit of determination is 0.28mg/m3 (calculated by carbon).
