| Abstract: | 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. |
