Role of Forensic Chemist in crime investigation

Abstract

Edmund Locard is the father of Forensic Chemistry. Forensic means scientific test or techniques used in connection with detection of crime. A Forensic Physician analyzes a variety of suspected substances, most often for law enforcement proposes. A Forensic Chemist can assist in the identification of unknown material found at a crime scene. Forensic Chemist uses G.C.- M.S.(Gas Chromatography- Mass Spectroscopy) analysis, A.A.S.(Atomic Absorption Spectroscopy), F.T.I.R.S.(Fourier Transform Infrared Spectroscopy), T.L.C.(Thin Layer Chromatography). A.A.S. is destructive and F.T.I.R.S is a non-destructive process to identify a substance.
