Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has established a rapid method for determining trace amounts of CO, CH4, and CO2 in polymer grade ethylene and propylene. The linear range and detection limit of the method have been verified, and the precision and recovery rate of the method have been investigated. The content of trace amounts of CO, CH4, and CO2 in actual samples of ethylene and propylene has been analyzed. The quantitative analysis results show that within the test concentration range, CO, CO2, The peak area and content of CH4 have a good linear relationship, with linear correlation coefficients greater than 0.990; The recovery rate is between 93.90% and 101.89%, and the relative standard deviation of the five repeated determination results is less than 2%, indicating accurate and reliable quantitative results; The minimum detection limits for CO, CH4, and CO2 are 31, 14, and 12, respectively μ L/m3 meets the needs of olefin production enterprises for quality control of olefin products. This method provides a new and highly sensitive analytical method for olefin product quality control in olefin production enterprises
