摘　　要：在PVC树脂生产过程中,常用气相色谱法分析原料氯乙烯中的杂质含量来指导生产工艺控制,但氯乙烯杂质组分多、含量低,为了准确测定,提高各组分分离效果,气相色谱固定相采用多组分混合而得。采用正交试验法进行试验获得了最佳的固定相组成,大大提高了检测工作效率,减少了人力、物力和时间的消耗。In the production process of PVC resins,gas chromatography was commonly used to analyze the impurity contents in vinyl chloride raw materials to guide the control of production process.But there were various impurities in vinyl chloride and their contents were low.So the gas chromatography fixed phase was multiplecomponent,in order to accurately determine and improve the separation effect of each impurity component.Thus,the best fixed phase composition was obtained by orthogonal test,which greatly improved the detection efficiency,and reduced the consumption of manpower,material resources and time.
