固相微萃取GC-MS快速分析火场残留物中汽油成分

Fast Analysis of Gasoline Ingredients in Fire Debris by GC - MS with Headspace Solid-Phase Microextraction

火场残留物如碳灰、烧残物等通常经过样品预处理后进行分析鉴定.传统的样品预处理方法往往操作繁琐、费时、重复性差,而且需用大量有机溶剂,不利于分析人员的身体健康,对环境也会造成一定污染.……

Solid-phase microextraction(SPME) is a new kind of pretreatment technology. It simplifies the traditional method of pretreatment and won't create secondary pollution. We use GC - MS with headspace solid-phase microextraction method to analyze the gasoline ingredients in fire debris, finding a sampling way and the analyzing condition.
