摘要
红外光谱法(IR)和拉曼光谱法(Raman)等快速检验技术可对气体爆炸现场中的爆炸遗留物和残留物进行快速检验和初步定性。本文结合一起可燃气体爆炸实际案例,利用手持式红外/拉曼光谱仪对爆炸遗留物、爆炸作用喷溅物进行快速分析,对快速定性检验和来源推断的应用效果和应用范围进行探讨。结果表明,该方法简单快速,检验对象多样,在气体爆炸现场关键物证的来源快速推断和现场快速重建工作中具有重要的应用价值。
Infrared and Raman（IR/Raman） spectroscopy,as represented of one quick detection technique,has been being applied for rapid determination of remnants and residues at gas explosion sites.In this paper,a hand-held integrated IR/Raman spectrometer was used to analyze the remnants and those splashed materials produced during a real combustible gas explosion.The efficiency and range were also probed on this fast detection technique to determine the specificity and source of evidential material.The results demonstrated that the rapid IR/Raman spectroscopic technique is applicable to a variety of analytes at a gas explosion site.With its simplicity and swiftness,this detection choice can play an important role in both the rapid provenancing of evidence and fast scene reconstruction for the related cases.
