摘要： 为火场样品中痕量汽油燃烧残留物的检测建立了一种便捷、高效的现场检测方法。通过模拟燃烧试验获取3种火场常见燃烧残留物：汽油与可燃材料木材燃烧残留物、汽油与不可燃材料混凝土燃烧残留物及汽油与土壤未燃烧残留物，分别放入便携式热脱附系统的空管内加热脱附，脱附后物质通过便携GC-MS分析。结果表明：3组模拟燃烧的样品均检出汽油残留物成分。因此，所建立的方法具有现场直接分析、无须样品前处理、杂质干扰小等特点，可用于实际火场样品中痕量汽油燃烧残留物的现场检测。

Abstract: A convenient and efficient method for the detection of trace gasoline combustion residues in fire site samples was established. Three kinds of common combustion residues in fire sites were obtained through simulated combustion experiments: gasoline and combustible wood combustion residues, gasoline and non-combustible concrete combustion residues, and gasoline and soil unburned residues, which were heated and desorbed in the empty pipe of portable thermal desorption system, and the deattached substances were analyzed by portable GC-MS. The results showed that gasoline residues were detected in the three groups of simulated combustion samples. Therefore, the established method has the characteristics of direct field analysis, no sample pretreatment, low interference from impurities, etc., and can be used for the field detection of trace gasoline combustion residues in actual fire site samples.
