Inductive Couple Plasma Atomic Emission Spectroscopy (ICP-AES) | ePoster 1
Channel: Forensic 365
Date: 2021-12-27

A new analytical method is proposed for the Pb, Ba and Sb quantifications on gunshot residues (GSR) from firearms using inductively coupled plasma optical emission spectrometry (ICP OES). Lead (Pb), barium (Ba) and antimony (Sb) concentrations in GSR from .38 revolver and .380 and .40 calibre pistols were determined as a function of the number of shots (from 1 to 5 for the .38 revolver and from 1 to 10 for the pistols) and a multiple linear regression model was constructed to determine the number of shots.
