Product Overview

Phenom Perception GSR desktop Scanning Electron Microscope (SEM) is designed for automated Gun Shot Residue (GSR) analysis for forensics investigations. This unique system combines automated GSR analysis and classification software with the easy-to- use Phenom XL desktop SEM and element identification.

Gunshot Residue (GSR) analysis plays an important role in the determination if a firearm has been used in a crime. A scanning electron microscope (SEM), is used to scan the sample and find “suspect” GSR particles. An Energy Dispersive Spectroscopy (EDS) technique is then used to identify the elements in these particles. Most common search criteria are the presence of Pb, Sb, and Ba. However, detection of Pb-free primers (such as Ti and Zn) can be a requirement as well.

Unlike other systems the Phenom GSR provides fully integrated software and hardware to enhance user-friendliness, reliability and analysis speed. Phenom GSR Perception software is highly intuitive and allows the user to analyse multiple samples automatically. Both EDS results and SEM images are stored for all detected particles, and the software allows the user to quickly and easily revisit each particle to validate results. Phenom GSR software also offers extensive reporting capabilities. The Phenom GSR software complies with the current ASTM E1588 standard guide for GSR and is equipped with the standard layouts as provided by ENFSI.
