| 摘 要： | 建立了以正己烷为溶剂、超声波震荡提取、气相色谱 质谱联用仪测定火场残留汽油中8种目标化合物的方法。各组分的浓度在0.1～50μg/mL范围内具有良好的线性，线性相关系数r2大于0.995,测定结果的标准偏差（n=7）小于5%。实际样品的测量结果表明，未烧汽油样品中甲苯含量高于其它7种目标化合物，在燃烧残留地毯中，仅可检验出3种目标化合物，而燃烧残留水泥块中可检出8种目标化合物。

| Abstract: | A method of gas chromatography-mass(GC-MS) spectrometry was developed for the quantitative analysis of gasoline trace in fire debris.Eight compounds,such as aromatic hydrocarbons,n-alkane and naphthalene,were selected as target compounds for quantitative analysis.The results showed that the linear range of eight compounds was 0.1～50 μg/mL with correlation coefficients r2 more than 0.995.The relative standard deviation(n=7) was less than 5%.Fire debris analysis indicated toluene showed the highest content in fresh gasoline.Three compounds were detected in carpet residues after burning,while eight compounds were detected in cement bricks. |
