Gunshot Residue Analysis

Gunshot Residue (GSR) analysis plays an important role in the determination if 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, an Energy Dispersive Spectroscopy (EDS) technique is used to identify the elements in that particle.

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.

The Phenom GSR desktop SEM comes with the following items:

  • Automated Gunshot Residue analysis and classification software package
  • Integrated BSED and EDS detector
  • Calibration sample
