中文摘要:

      采用气相色谱-质谱(GC-MS)联用技术,根据汽油原样中的特征成分,对未加入和分别加入汽油燃油精、海龙燃油宝的汽油燃烧烟尘进行对比分析. 结果表明,汽油燃油精的加入会使汽油燃烧烟尘中各类特征成分的百分含量有所变化,但对谱图和特征成分的影响较小;而海龙燃油宝的加入对汽油燃烧烟尘的谱图、特征成分及其个数、各类特征成分的百分含量均产生较大影响. 结果为火灾物证鉴定提供一定的参考依据.

英文摘要:

      Three gasoline combustion smoke dust samples, i.e. from burning gasoline, burning gasoline with one fuel additive and burning gasoline with another fuel additive, were prepared and analyzed by gas chromatography-mass spectrometry (GC-MS). The results showed that the percentages of the characteristic components were changed, the spectrogram and the characteristic components were slightly affected by one fuel additive. But the spectrogram, characteristic components and percentages of the characteristic components in gasoline with another fuel additive were greatly affected. The results can provide some reference basis for the fire material evidence identification.
