气相色谱法测定丙烯中的COS、H_2S和AsH_3

Determination of COS,H2S and AsH3 in Propylene by Gas Chromatography

介绍一个用石英毛细管柱和脉冲火焰光度检测器（Ｐｌｓｅｄｆｌａｍｅｐｈｏｔｏｍｅｔｒｉｃｄｅｔｅｃｔｏｒ简称ＰＦＰＤ），测定丙烯中微量ＣＯＳ、Ｈ２Ｓ及ＡｓＨ３的气相色谱分析方法。实验结果表明，该法具有操作简单、样品用量少、精度高、重复性好，以及连续运行周期长等特点。可满足聚丙烯生产及原料分析的需要。

A GC analytical method for trace COS,H2S and AsH3 in propylene has been developed by using a quartz capillary column and a pulsed flame photometric detector (PFPD).The results show that the method is simple,rapid,sensitive and accurate for practical purposes.It is also characteristic of good reproducibility and long lifespan under continuous operation,and can meet the requirements of routine analysis for polypropylene production and raw material quality control.
