摘要
汽油和柴油是放火刑事案件常用的助燃剂,为了鉴定火场中是否存在汽油或者柴油,采用气相色谱/质谱联用(GC-MS)分析技术,对模拟火场条件下燃烧后的汽油和柴油残留物组分进行分析,并与国家标准进行对比。试验结果表明,汽油与柴油燃烧残留物在成分和保留时间上都有很大的不同;载体对燃烧残留物的组成成分有一定的改变,但不会影响对油品的鉴别判定。
Gasoline and diesel are the most common flammable liquids accelerant,and are also the common flammable liquids for incendiary criminal cases. To authenticate whether there is gasoline or diesel or not in a fire,the experiment analyzed and identified the gasoline and diesel residues on the conditions of simulated fires by the analysis technology of the gas chromatography mass spectrometry( GC- MS) and the contrast with the national standards.The result shows,gasoline and diesel combustion residues on the composition and retention times are very different;the vector has produced some change on components of combustion residues,but it does not affect the identification and qualification of oil.
