光谱分析结合化学计量学方法在法庭物证鉴定领域中的应用进展

Application Progress of Spectral Analysis Combined with Chemometrics in Forensic Identification

近十年来,现代光谱仪器分析技术与化学计量学方法相结合,被广泛应用于物证领域的分类预测,从而实现对物证自身特征信息的准确识别和分析。详细论述在法庭物证鉴定光谱分析过程中使用的化学计量学方法,比较它们的优缺点以及适用性,并综述光谱分析结合化学计量学方法在食药品检验、微量物证检验、生物物证检验和文件检验4个重要法庭物证鉴定领域中的应用进展,以期推动化学计量学在法庭科学中的进一步研究及应用。

In the past decade,modern spectral instrument analysis technology and chemometrics had been applied to the classification and prediction of physical evidence,so as to realize the accurate identification and analysis of the characteristic information of physical evidence.This paper discussed in detail the chemometrics methods used in the spectral analysis of forensic material evidence identification,compared their advantages and disadvantages and applicability,and summarized the application progress of spectral analysis combined with chemometrics in four important forensic material evidence identification fields:Food and drug inspection,trace material evidence inspection,biological material evidence inspection and document inspection,in order to promote the further research and application of Chemometrics in forensic science.
