Forensic Analysis of Gunshot Residue
Reconstruct Crime Scenes Where Firearms Were Used
Classify and distinguish Gunshot Residue (GSR) from environmental particles. Reconstruct crime scenes where firearms were used. Gunshot residue (GSR) is particles that originate from partially reacted components of explosive primer and propellant as well as the bullet, cartridge case, and the firearm.

GSR= Gunshot Residue made of Ti and Zn - SEM EHT=20kV Detector: NTS BSD WD: 8.5mm
GSR= Gunshot Residue made of Ti and Zn - SEM EHT=20kV Detector: NTS BSD WD: 8.5mm
Unique GSR particles show a specific chemical signature; most commonly the combination of lead, barium, and antimony. In addition, GSR particles from lead-free type ammunition (Sintox) can be examined. Scanning electron microscopes with energy dispersive x-ray spectroscopy allow the identification of very small amounts of GSR particles and the subsequent analysis of the surface morphology and composition of individual GSR particles with high accuracy.
