Phenom Perception GSR Desktop SEM
SEM EDX gunshot residue analysis with desktop SEM
Gunshot residue (GSR) analysis is critical in determining whether a firearm was involved in a crime. Standard GSR analysis techniques utilize a scanning electron microscope (SEM) to examine samples and detect potential GSR particles. Once a suspect particle is identified, energy dispersive spectroscopy (EDS) is employed to analyze the elemental composition of the particle.
The Thermo Scientific Phenom Perception GSR Desktop SEM is the only SEM specifically designed for GSR analysis. Its automated system accelerates the analysis process by eliminating the need for frequent adjustments, allowing you to focus directly on your work.
Powered by a high-brightness CeB6 source, the Phenom system ensures dependable, long-lasting daily operation without unexpected replacements. The Phenom Perception GSR Desktop SEM streamlines gunshot residue analysis, making it faster, easier, and more reliable—ideal for any busy laboratory seeking to save time and conserve space.
Key benefits include:
- A dedicated solution for gunshot residue analysis
- Minimal laboratory space requirements
- Stable, round-the-clock operation
- Long-lasting CeB6 source for reliable performance
Features
High throughput, reliable results
Thanks to the fully motorized stage, the Phenom Perception GSR Desktop SEM can handle a scan area of 100 mm x 100 mm. The software uses the internal scan control of the SEM. This enables more accurate beam positioning which especially helps when revisiting the particle in the GSR verification phase. A standard GSR sample holder can hold 30 12mm GSR pin stubs plus the necessary calibration samples.
Fully integrated EDS
The dedicated software package Element Identification (EID) is used to control the fully integrated EDS detector. This EID software is delivered standard as part of the Phenom Perception GSR product.
