模拟火灾现场情况,以93#汽油为研究对象,制备了93#汽油在两种载体上不同燃烧程度的燃烧残留物,采用薄层色谱扫描技术对燃烧残留物进行实验研究。结果表明不同载体及不同燃烧程度对93#汽油燃烧残留物中存在的特征组分都会有一定的影响,该实验研究结果,可以帮助火灾调查人员判断火灾现场93#汽油的存在与否提供依据,也可以为此类物证鉴定提供参考。
Simulated the scene of the fire, taking 93 # gasoline as the research object, the combustion residues of 93 # gasoline with different combustion degree on two kinds of carriers were prepared and the combustion residues were experimentally studied by TLC. The results show that different carriers and different degrees of combustion of 93 # gasoline combustion residues in the presence of the characteristic components will have some effect on the experimental results can help fire investigators to determine the presence of 93 # gasoline on the scene of the fire to provide a basis, Can also provide reference for such evidence identification.
