摘　　要：采用三阀-四柱-三检测器-三通道气相色谱法对碳二加氢混合组分的分析进行了研究,对仪器重复性、准确性进行了考察,在此基础上,对传统采用的体积(摩尔)外标法的影响因素进行了探讨,在此基础上提出一种新的分析方法—质量归一化法,该方法避免了进样速率(压力)对分析结果的影响,具有更强的实用性和准确性。The application of three valve-4-three channel-three detector gas chromatography on C2 hydrogenation mixed component analy- sis was studied, and the instrument repeatability, accuracy was investigated.on the basis of this analysis, the influence factors of volume （mol） extemal standard method were analyzed, and a new analysis method- mass normalization method was put forward. This method avoided the sample rate （pressure） effect on the analysis result, had stronger practicability and accuracy.
