Using pure polyvinylidene chloride as raw material, a new type of non-polar chromatographic carrier with large specific surface area, carbon molecular sieve, can be obtained through thermal degradation reaction. Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. put forward the application of carbon molecular sieve column in the analysis of trace impurities by discussing the preparation and performance of carbon molecular sieve. The work results show that the gas chromatography method using carbon molecular sieve with a column length of only 0.5 m as the stationary phase is fast, sensitive, accurate and convenient for the quantitative analysis of trace acetylene in the separation and hydrogenation process of petroleum gas. The lifespan is also very long.
