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。
The actual handling of cases, often involving the identification of traces of laundry detergent evidence. In this paper, microscopic laser Raman spectroscopy techniques were used to test the washing powder evidence. The collected different brands of washing powder and the same brand of different types of detergent samples were detected by Raman microscopy laser Raman spectroscopy. Through the spectral analysis and comparison to achieve different types of detergent evidence of rapid non-destructive testing.
