光谱分析技术鉴定未知爆炸物

摘要

In view of identification of unknown explosive material from criminal investigation process, the chemical separation and spectral analysis technologies such as the infrared spectrum, the X-ray fluorescence spectrum, the scanning electron microscope united with the power spectrum, were used in determination of the industry ammonia dynamite, the black powder, the detonator and different type of common explosive materials. The application of spectral technique in the unknown explosive material's appraisal was summarized. The result indicated mat the spectral analysis technology has merits of more convenient, fast, few sample, and safe. The determination to unknown and doubtful explosive material can be quick and accurate.%针对刑侦过程中采集的疑似爆炸物物证的鉴定,介绍了运用化学分离及红外光谱、X射线荧光光谱、扫描电镜与能谱联用等光谱分析技术,对工业硝铵炸药、黑火药、雷管等不同种类常见爆炸物的快速技术鉴定程序,总结了光谱分析技术在未知爆炸物鉴定中的应用.结果表明光谱分析技术具有较爆炸试验更方便、快速、所需样品少且更加安全等优点,可快捷、准确地对未知及疑似爆炸物进行检验、判定.
