应用 Varian 380 0 GC/ Saturn 2 0 0 0 MS气相色谱 /质谱联用分析仪 (简称 GC/ MS/ MS)对以汽油、煤油和柴油为引燃物 ,燃烧聚丙稀化纤地毯和土壤时的模拟现场物品进行了引燃物的检出。发现采用 GC/ MS/ MS方法比用 GC/MS方法可以较彻底地排除由于柱流失、地毯燃物分解产物、土壤背景产物和地毯增塑剂等引起的干扰 ,而且可以提高检测灵敏度。详细考察了以不同质荷比的离子作母离子时对 GC/ MS/ MS分析结果的影响。质荷比为 10 6的离子是作母离子的最优选离子 Simulation of Combustion of Polypropylene Fiber Carpet and Soil with Gasoline, Kerosene and Diesel as Fuel by GC / MS / MS with Varian 380 0 GC / Saturn 2000 Analytical Instrument (GC / MS / MS) Site items were detected ignition. It is found that the GC / MS / MS method can more completely eliminate the interference caused by the column loss, carpet fuel decomposition products, soil background products and carpet plasticizers, etc., and can improve the detection sensitivity. The effects of different mass-to-charge ratio of ions on the GC / MS / MS analysis were examined in detail. Ions with a mass-to-charge ratio of 10 6 are the most preferred ions for the parent ion
