摘要: 以橡木地板、株木实木桌等10余种木制品为研究对象,利用固相微萃取-气相色谱质谱法(SPME-GC/MS)和固相微萃取-全二维气相色谱-质谱法(SPME-GC×GC/MS)对木制品本体样品进行分析,探究其对纵火现场助燃剂汽油分析鉴定的影响。结果表明,利用SPME-GC/MS技术在株木实木桌本体样品中检出与汽油中成分完全相同的C2、C3和C4烷基苯以及烷基萘类化合物,对汽油分析鉴定干扰较大,其他木制品对汽油分析干扰较小;对分析汽油干扰较大的株木实木桌本体样品继续采用SPME-GC×GC/MS技术进行综合分析,给出了对比分析结果,排除了此类样品对分析汽油的干扰,准确度较高。

Abstract: With more than 10 kinds of wood products such as oak floor and wood table as the research objects, SPME-GC /MS and SPME-GC×GC/MS were used to analyze the body samples of wood products and explore their influence on the analysis and identification of combustion-supporting agent gasoline at the scene of arson. The results showed that C2, C3, C4 alkyl benzene and alkyl naphthalene compounds, which were exactly the same as those in gasoline, were detected by SPME-GC/MS in the real wood table body samples. SPME-GC×GC/MS technique was used to analyze the solid wood table body samples with large gasoline interference, and the results of comparative analysis were given, which eliminated the interference of such samples on the gasoline analysis with high accuracy.
