摘　　要：目的建立检验纵火案件现场燃烧残留物中助燃剂汽油成分的方法。方法利用自动热脱附技术对火场残留物中的助燃剂进行富集、浓缩、脱附后经气-质联用仪(GC-MS)分析。结果结合现场燃烧环境运用目标化合物法能够判定是否含有助燃剂汽油成分。结论该方法简便易行。Objective To present a method for accelerant gasoline identification in fire debris. Method Ignitable liquid residues from fire debris samples were adsorbed and concentrated by automatic thermal desorption system, then analysed by gas chromatography-mass spectrometry. Result The target compounds of gasoline were detected. Conclusion The means is simple, convenient and practical.
