摘要: 通过对火场常见塑料载体与助燃剂混合燃烧残留物的分析，发展一种适用此类燃烧残留物的火灾物证鉴定方法，对火场中是否存在助燃剂进行判断，避免漏检情况的发生。应用热分析技术确定合适的闪蒸温度，在此温度下对塑料载体与助燃剂混合燃烧残留物进行闪蒸分析，并从实验条件选择、可行性分析、定性分析三方面对闪蒸技术进行评价。结果表明，闪蒸气相色谱-质谱（Flash GC-MS）技术可以检测到热塑性聚合物塑料载体与助燃剂混合燃烧残留物中残留的助燃剂特征组分，可对火场中是否存在过助燃剂进行辨别。闪蒸气相色谱-质谱技术丰富了现代火灾物证鉴定技术，能进一步辅助火灾物证鉴定工作，使鉴定结论更准确、可靠。

Abstract: A method of fire evidence identification applicable to combustion residue was developed by analyzing the combustion residue of a common plastic carrier and accelerant in a fire field. The method could detect the presence of the accelerant in a fire field, thereby preventing missed identification. The appropriate flash temperature was determined by thermal analysis. The combustion residue of the plastic carrier and accelerant was analyzed by flash technology under the appropriate flash temperature. The application of flash technology was evaluated in terms of a range of different experimental conditions, alongside feasibility and qualitative assessments. We found that the optimum flash evaporation temperature was 300℃ when analyzing the combustion residue corresponding to polyethylene (PE) and polyethylene terephthalate (PET) carrier. Experimental results showed that flash gas chromatography-mass spectrometry (Flash GC-MS) extracted the characteristic residual components of the accelerant and could be used to distinguish whether an accelerant was present in a fire or not. The application of flash evaporation technology to fire evidence identification provides a more complete and accurate analysis of the components of combustion residue, eliminating interference factors. Flash GC-MS enriches the modern fire evidence identification toolkit and can support current methods, leading to more accurate and reliable identification.
