　　Haohan Chromatography (Shandong) Application Technology Development Co., Ltd., combined with the actual situation of daily monitoring, applies the dual column and dual detector gas chromatography method to explore key technical issues such as standard gas, sampling medium, chromatographic conditions, and gas flow rate. The results indicate that using methane standard gas can shorten the analysis time, preserve the gas in the gas bag for a longer time, optimize chromatographic conditions to quickly remove impurities inside the column, and the gas flow rate ratio affects the area of the oxygen peak.
