木质装修材料燃烧烟尘气体的热解吸GC-MS分析

The Combustion Smoke of Wood-decorative Materials by Thermal-adsorption GC-MS Analysis

对93#汽油、6种装修用木材及其汽油浸染物分别进行了燃烧试验,对燃烧产生的烟尘气体利用分子筛吸附管进行了采集,再利用热解吸气相色谱质谱(GC-MS)分别对采集物进行了分析。结合参考相关文献,谱图对比研究结果显示:苯、苊、带支链的环烷烃、蒽或菲相对适宜作为判断木材受汽油浸染的分子物证。

In this work,combustion experiments were carried out respectively using the samples of gasoline 93#,six sorts of wood-decorative materials and the materials wetted with the gasoline.Smokes derived from the experiments were collected with molecular sieve adsorption tubes,and analyzed by gas chromatography-mass spectrometry（GC-MS） with thermal-adsorption sampling system.Our result suggests that mass spectrometric features of benzene,acenaphthene,cyclane,anthracene or phenanthrene would become markers tracing the wood-decorative fire triggered by gasoline.
