Utterly reliable GSR analysis results

Every particle counts in gunshot residue (GSR) analysis, and the Thermo Scientific Phenom ParticleX GSR Desktop SEM delivers round-the-clock, in-depth analysis to identify even the smallest GSR particles with utmost accuracy. This system is built to deliver utterly reliable results, crucial for forensic investigations where precision is non-negotiable. It stands out as an indispensable tool for forensic laboratories, providing reliable, fast, and accurate GSR analysis that meets the evolving needs of modern forensic science.


Fast scanning electron microscopy

The Phenom ParticleX GSR Desktop SEM maintains high quality while drastically accelerating your throughput—and your return on investment. Its advanced technology delivers fast analysis without compromising on the detail and accuracy required for forensic work.


Automation makes GSR analysis easy

Thermo Scientific Perception Software delivers automation to help you work smarter and faster, with minimal intervention. For example, internal scan control provides more accurate beam positioning, which is key when revisiting particles during the GSR verification phase. This level of automation reduces manual work so you can focus on more critical tasks.


Extensive elemental analysis with SEM EDS

Integrated energy dispersive spectroscopy (EDS) helps you analyze the elemental composition of GSR powder, a vital requirement for forensic lab teams. Typically, this technique is used to search for the presence of lead (Pb), barium (Ba), and antimony (Sb) particles. However, with the advent of Pb-free primers, detecting titanium (Ti) and zinc (Zn) is also essential. The Phenom ParticleX GSR Desktop SEM supports customizable rules for Pb-free ammunition, ensuring comprehensive analysis across different types of ammunition.


Reporting compliant with ASTM E1588-17

The Phenom ParticleX GSR Desktop SEM generates reports that are compliant with ASTM E1588-17 standards, helping your forensic reports meet the highest industry benchmarks. This compliance is critical for the credibility and acceptance of forensic evidence in legal contexts.
