摘　　要：应用气相色谱法(氦离子化检测器)同步测定丙烯中砷烷、磷烷及MAP(不饱和轻烃)组分。探讨了色谱柱筛选、阀柱系统设计、柱箱温度、载气流速等仪器参数条件设置,用标准气体进行方法验证,各组分检出限≤0.1 ppmV,相对误差在-2.0%~2.0%之间,相对标准偏差小于1.5%,生产应用效果好。Simultaneous determination of arsenic,phosphorus,and MAP(unsaturated light hydrocarbon)components in propylene using gas chromatography(helium ionization detector).The instrument parameter settings such as chromatographic column screening,valve column system design,column box temperature,and carrier gas flow rate were discussed.The method was validated using standard gas,and the detection limit of each component was≤0.1ppmV.The relative error was between-2.0%and 2.0%,and the relative standard deviation was less than 1.5%.The production application effect was good.
