Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has conducted research on the method of using portable monitors to analyze total hydrocarbons, methane, and non methane total hydrocarbons in the air. The sampling probe configured with portable monitors is used to collect air samples and conduct on-site analysis. This method uses catalytic oxidation to quickly and effectively quantitatively analyze methane and non methane total hydrocarbons in the ambient air, with a correlation of up to 0.999, The relative standard deviation is less than 1.7%, the minimum detection limit is 0.05-0.07mg/m3, the conversion efficiency of ethane is 98.2%, the methane loss rate is 13.1%, the conversion efficiency of the catalyst meets international standards, and the analysis period is less than 2 minutes. This method has high accuracy and good repeatability, and is suitable for rapid monitoring of non methane total hydrocarbons in ambient air
