Product Overview

Phenom 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 software is based on a four-step wizard to consistently set up the software in order to receive fast and reliable results from each run. The wizard 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.

Benefits

All in one imaging and analysis

Compact desktop SEM with X-ray (EDS) analysis that needs little space and no extra facilities that allows sample structures can be physically examined and their elemental composition determined.

Super-fast

After loading the sample an instant optical image is received followed by an electron image in <60 seconds.

Ease of use with “never lost” sample navigation

Equipped with an optical colour microscope the user can swiftly navigate to any region of interest with just a single click and keep the image overview of the sample.

Low maintenance

The long lifetime, high brightness thermionic source (CeB 6 ) enables extremely stable operation and has a typical operational lifetime of >1500 hours, which is ideal for maximum useability, serviceability and uptime.

Intuitive software

Automated analysis and classification software uses a four step wizard that allows the user to achieve fast and reliable results. Phenom GSR software is ASTM E1588 compliant.
