The Application Status of Fourier Transform Infrared Spectroscopy in Forensic Science
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.
