2021 Methane Capillary Column
2021 Methane Capillary Chromatographic Column Details:

Methane capillary column:

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

Specification: 30m*0.53mm*25um
Model: HH-PLOT-Molecular sieve
Application: Determination of ambient air/stationary pollution source exhaust gas, methane, total hydrocarbons, non-methane total hydrocarbons, gas chromatography



Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. adopts ten-way valve sampling, the total hydrocarbon column is separated from the methane dedicated column, and the gas chromatography method with a single FID detector can be used to measure methane and total methane in ambient air or stationary sources. The detection data of hydrocarbons and non-methane total hydrocarbons. The experiment clarified the interference of oxygen peaks on total hydrocarbons during the analysis of gas samples with different oxygen content, and pointed out the feasibility of avoiding separate detection of hydrocarbon-removing gas samples. The experiment uses syringe sampling, and the sample The best storage time is within 8h. The detection limit of the method is: total hydrocarbons and non-methane total hydrocarbons are both 0.04 mg/m3; the relative standard deviation of repeatability is less than 1.5%; the method's standard recovery rate is total Hydrocarbons are between 90.3% and 113.0%, and total non-methane hydrocarbons are between 91.1% and 110.0%.
