The intention of this paper was to review and discuss the some of the quantitative analytical methods used in forensic science for the analysis of trace evidences collected from the various scene incidents. The forensic scientists were depend upon the instrumental analysis of trace amounts of materials like drugs, toxicological specimens, fibers, glass, GSR, soil, etc. Differences in manufacture of chemical composition are observed and that allows considerable discrimination even with very small traces of fragments. Most on GSR, GSR analysis sometimes becomes very important to right direction of inquiry, from where the GSR is obtained and from which surfaces the GSR has produced, played an important aspect of investigations. Reviews on these techniques, which are used more extensively in forensic sciences, were reported through this paper. Based on the analytical problem facing forensic scientists, our study will summarize and use these techniques to tackle them such as chromatography, Raman spectroscopy, Atomic Absorption Spectroscopy, Inductively Coupled Plasma (ICP) techniques.
