摘要
将国标GB/T3395-93测定乙烯中微量乙炔的方法进行了改进,采用大口径碳分子筛石英毛细管柱代替了原方法中的填充柱,对色谱操作条件进行了优化,该法具有分析速度快、重复性好、准确度高的特点,适用于乙烯产品及中控的分析,有较大的实用价值。
Determination of trace acetylene in ethylene by chromatography was improved, packed column used originally was replaced with carbide molecule screen capillary column and condition of chromatograph was modified. Baseline of chromatograph was stable, effect separate of chromatograph got well, analysis time was saved. The new method was simple, rapid, repeatable, accurate and fit for products and control analysis for trace acetylene of ethylene in ethylene plant.
