Determination of Methane in Ambient Air by Gas Chromatography Details:

Name: GDX-502 Methane Column

Specifications: 2m*1/8, 60-80 mesh

Number: 20220630003

Temperature: 250°C



application:

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

HJ 604-2017HJ 604-2017 Ambient air-Determination of total hydrocarbons, methane and non-methane total hydrocarbons-Direct injection-gas chromatography


Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. used double-column double-hydrogen flame ionization detector gas chromatography to determine non-methane total hydrocarbons in ambient air. The detection limit of the method: total hydrocarbons are 0.02mg/m3, methane is 0.02 mg /m3, non-methane total hydrocarbons are 0.02 mg/m3. Coefficient of variation: total hydrocarbons are 0.65%, methane is 0.55%, non-methane total hydrocarbons are 3.06%. Standard addition recovery: total hydrocarbons are 101.2%~102.7%, methane It is 100.7%~101.8%. The method is feasible and suitable for the determination of non-methane total hydrocarbons in ambient air.
