Gunshot Residue (GSR) analysis plays an important role in the determination when a firearm has been used in a crime. Established GSR analysis techniques are based on the use of a Scanning Electron Microscope (SEM), which is used to scan the sample and find suspect GSR particles. If a suspect particle is found, Energy Dispersive Spectroscopy (EDS) technique is used to identify the chemical composition of that particle. Most common search criteria are the presence of Pb, Sb, and Ba. However, detection of Pb-free primers, such as Ti and Zn, is a requirement as well.
Thermo Scientific Phenom Perception GSR is the world’s first dedicated Desktop SEM that can run automated GSR analysis. It is based on the Phenom XL Desktop SEM. Both software and hardware are fully integrated to enhance user-friendliness, reliability and analysis speed.

Application - Gunshot Residue Analysis

Perception GSR software works based on recipes that are easy to custom build from standard building block. Once a Standard Operating Procedure (SOP) is determined for your lab it is easy to execute pre-set recipes for different cases. The stage layout in combination with the Navigation Camera of the Phenom Desktop SEM makes it fast to adjust runs for multiple samples. Full automated particle location and EDS analysis will give repeatable results. Revisiting is intuitive with the high accuracy stage and will automatically generate detailed confirmation reports.
