| 摘 要： | 摘 要：为分析特征温度对放火火灾中汽油检测的影响，利用气相色谱质谱联用技术，以汽油燃烧残留物为研究对象，通过热分析技术选定特征温度点，并对不同特征温度下样品组分的变化情况进行GC-MS分析。研究结果表明，温度的升高可以改变汽油的理化性质，加快汽油组分的流失，对汽油燃烧产物的检出效果造成影响。研究可为实际工作提供更准确的鉴定意见。

| Abstract: | In order to analyze the influence of characteristic temperature on gasoline detection in arson fire, this paper uses the gas chromatography and MS combined technology to study the gasoline combustion residue, selects the characteristic temperature points through the thermal analysis technology, and conducts GC-MS analysis on the changes of sample components at different characteristic temperatures. The results show that the increase of temperature can change the physical and chemical properties of gasoline, accelerate the loss of gasoline components, affect the detection effect of gasoline combustion products. The study can provide more accurate identification opinions for practical work. |
