STUDY TO ESTABLISH THE PRESENCE AND QUANTIFICATION OF THE ELEMENTS AT VARIOUS RANGES

Abstract

One of the most important and most conventional subjects of forensic science is ballistics. This is the study of
firearms and ammunitions. In most of the crimes those are related to firearms, there is a need of in-depth analysis in the
involved material such as the firearm and bullets and the residue particles.
Though various microscopic examination and analysis are available for the identification of the firearms and ammunition,
the reliable sources of information about the individual about the evidence of fire or gunshot is established through the
gunshot residue analysis. By the terminology itself, it is understood that the analysis is being done on the residual matter
obtained from the gunshot. This would be useful to determine the type of weapon or ammunition involved in the specific
crime or incidence. So we present in this study of GSR analysis by SEM-EDX, EDXRF at various ranges from we collect the
GSR. We explore the Qualitative and Quantitative analysis of GSR particle at various ranges to determine the presence of
GSR particle at various ranges.
