摘　　要：本文模拟火灾现场制备汽油燃烧残留物,利用气相色谱-质谱(GC-MS)联用分析仪,对燃烧残留物进行分析,比较三种不同进样方式下GC MS谱图的稳定性。结果表明,不同进样方式下的GC-MS谱图的稳定性有明显的不同。Gas chromatography-mass spectrometry was used to analyze the gasoline burning residues collected from a simulated fire scene.The stabilities of spectra of GC-MS analyses with three different sampling methods were compared.It was shown that the stabilities of spectra obtained by using different sampling methods were different obviously.

关 键 词：GC-MS 残留物 进样方式 稳定性
