Gunshot Residue (GSR) Analysis

Phenom GSR - Phenom-World BV. (PhenomWorld)

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.
