摘要
利用红外气体池法分析火灾现场汽油残留物,探索和优化实验条件,获取汽油残留成分的红外特征吸收峰。针对模拟火场燃烧残留物的检验,考察燃烧载体、燃烧时间、汽油的用量等因素对于检验结果的影响。结合实际案例,应用红外气体池法进行检验鉴定,并与常规GC/MS分析手段检验的结果进行比较。研究表明,红外气体池法快捷有效,为火灾现场汽油残留物的检验提供了一种新的研究思路。
Residual gasoline on fire scene was analyzed by the method of infrared gas cell. The experimental conditions were explored and optimized, and the infrared absorption characteris- tics of residual components of gasoline were obtained. According to the simulated fire burning residue test,the influence of burn- ing carrier,burning time, the amount of gasoline and other fac- tors on the test results was inspected. With the example of actu- al case, infrared gas cell inspection was used and compared with GC/MS analysis. The research showed that infrared gas cell was an efficient and effective method for testing the residual gasoline on fire scene,which provided us a new research idea.
