The Phenom XL desktop SEM features the largest sample chamber of any tabletop SEM while maintaining all of the advantages of the original Phenom platform.

  • Automated Gunshot Residue analysis and classification software based on Perception software
  • SEM and EDS are integrated into one easy to use software package
  • Calibration sample
  • Fastest vent/load cycle for high throughput
  • Motorized XY sample stage
  • Color optical camera for single-click navigation
  • Charge reduction mode reduces need to coat samples
  • Small footprint
  • No infrastructure needed
Sample Holder for Phenom XL Scanning Electron Microscope

High Throughput, Reliable Results

The Phenom XL Perception GSR comes equipped with a chamber that can handle a scan area of 100 mm X 100 mm. The software uses the internal scan control of the SEM, enabling accurate and precise beam positioning for the GSR particle verification step. The standard sample holder allows for automated analysis of up to thirty (30) 12mm GSR pin stubs plus the necessary calibration samples. Sample loading is simple and easy, and the proprietary venting/loading mechanism ensures the fastest vent/load cycle in the world.

Perception GSR Software for Phenom XL Desktop Scanning Electron Microscopes

Phenom Perception GSR Software

Perception GSR software allows individual labs to easily create custom recipes based on standard operating procedures (SOPs). Based on a standard building block recipe interface, data acquisition can be fully automated for particle location and EDS analysis with reliable and repeatable results.
