摘　　要：讨论了气相色谱脉冲火焰光度检测器(GC-PFPD)法分析丙烯中微量硫化物的影响因素,建立了丙烯中硫化物的定性及定量测定方法,对仪器稳定性、柱温、进样量及分流比、标准气体和采样容器等几个方面进行探讨。通过试验,确定了影响分析的主要因素并提出优化措施,提高了分析结果的准确度。The optimum conditions for measurement of sulfur components in propylene with gas chromatography-pulsed flame photometric detector(GC-PFPD)were discussed.Qualitative and quantitative measuring methods of sulfur components in propylene were primarily established.The influence of the operating parameters of the commonly used GC-PFPD on the measurement result was investigated.The affecting factors of stability of instrument,column temperature,sample size,split ratio,standard gas and the sampling container were discussed.It makes that the influence factor of analysis,and increase the accuracy of results.
