Monitoring and Analysis of Methane, Total Hydrocarbons and Non-Methane Total Hydrocarbons in Atmosphere
Monitoring and analysis of methane, total hydrocarbons and non-methane total hydrocarbons in the atmosphere Details:

Methane capillary column:

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

Specifications: 30m*0.53mm*25um

Model: HH-PLOT-Molecular sieve-II

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

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. adopts six-port valve injection, dual capillary column, dual FID detector gas chromatography, and can measure CH4, total hydrocarbons and non-methane total hydrocarbons (NMHC) in the atmosphere with one injection. ) test data. At the same time, the oxygen peak in the FID detector in the chromatogram can be initially identified as "interference peak", which can be ignored in the analysis. The detection limit of the method: CH4 0.03mg/m3, total hydrocarbons 0.04mg/ m3, NMHC0.06mg/m3. Variation coefficient: CH4 3.81%, total hydrocarbons 2.07%, NHMC 5.07%. Standard recovery: CH4 96.1%, NHMC 96.1%～98%.
