摘要
傅里叶变换红外光谱技术因其方法简单快捷、结果准确直观、样品损耗小、检测成本低廉而被认为是适合分析各类物证的技术之一。通过介绍傅里叶变换红外光谱技术的原理及运用傅里叶变换红外光谱技术进行死后间隔时间推断、避孕套有关成分分析、微生物鉴定、土壤分析和车辆物证分析等几个方面阐述了其在法庭科学领域中的研究和应用现状,希望能够为该技术在法庭科学中的应用提供参考,并为鉴定相关案件中的物证提供一种新的思路。
Fourier transform infrared spectroscopy(FTIR)is considered to be one of the techniques suitable for analyzing various kinds of material evidence because of its simple and fast method,accurate and intuitive results,low sample loss and low detection cost.This paper introduces the principle of Fourier transform infrared spectroscopy and its research and application in the field of forensic science in several aspects such as postmortem interval inference,condom component analysis,microbial identification,soil analysis and vehicle material evidence analysis.It is hoped that this review can provide a reference for the application of this technology in court science,and provide a new way of thinking for the identification of material evidence in related cases.
