显微拉曼光谱法对微量洗衣粉的区分检验研究
Rapid Discrimination Examination of Trace Washing Powder by Micro-Raman Spectroscopy
摘要
实际办案工作中, 时常会涉及到对微量洗衣粉物证的检验鉴定。本文应用显微激光拉曼光谱分析技术对洗衣粉物证进行了检验研究。将所收集到的不同品牌的洗衣粉及同种品牌不同种类的洗衣粉样品采用显微激光拉曼光谱仪进行检测得到拉曼光谱图。通过谱图分析比较实现了对不同种类洗衣粉物证的快速无损区分检验。
Abstract
It often involves the examination of trace evidence of washing powder in actual cases. In this paper, the method of rapid analysis of washing powder by Micro-Raman spectroscopy is studied. We obtain the Raman spectrum of the collected washing powder of different kinds or brands by micro laser Raman spectrograph. Through the analysis of spectrums, we realized a fast and nondestructive method for detection of different washing powder samples.
