✓ Detectors: compatible with all Oxford Instruments EDS detectors, including legacy models. No detector upgrade required.
! Base software: requires AZtecFeature to be purchased, installed and licensed first. AZtecGeo is an application module that runs inside AZtecFeature.
! Software: requires AZtec 6.2 or later already installed on your acquisition PC. Check your version and how to update.
✓ Microscope: any SEM or FIB-SEM running AZtec. Automated stage control is needed for large-area runs.
Only one license can be generated per order.
Once you have purchased AZtecGSR you will receive the product key in an email notification from no-reply@estore.oxinst.com or noreply.NA.softwarelicensing@sentinelcloud.com, which will also include instructions on how to activate the licence.

AZtecGSR is an application module for AZtecFeature. It is not a standalone product. You must already own and have installed AZtecFeature on your acquisition PC. Because AZtecGSR runs inside AZtecFeature, it inherits the same hardware compatibility: it works with every Oxford Instruments EDS detector and with any SEM or FIB-SEM that already runs AZtec.
Gunshot Residue is a key piece of forensic evidence that is often critical to ensuring justice in some of the most serious crimes. AZtecGSR provides fast, accurate and easy to use SEM-based GSR analysis for the forensic analyst.
Designed for analysis according to industry best practice guidelines, AZtecGSR uses a workflow-based approach to guide both expert and novice users through GSR analysis, with in-interface instructions for additional guidance. It includes advanced functionality for dealing with the very small particles often found in GSR work, and approaches for improving throughput when running a large number of samples.
• Optimised analytical recipe for GSR analysis
• Automatic data collection and particle classification to ASTM-E1588 16, 17, 20 and 25
• Classification scheme that indicates which brand of ammunition may have been used
• Manual and automatic particle reacquisition modes, with a confirmation routine for reacquired particles
• Add new classifications for new ammunitions
• Automatically acquire additional data from particles containing key elements
• Terminate analyses automatically once sufficient evidence has been acquired
• Use the same software platform to follow up with other techniques such as EBSD
• Analysis rates in excess of 120,000 particles per hour, dependent on hardware configuration
• Combine up to four Ultim Max Infinity detectors for maximum throughput
• Manage multiple analysis runs simultaneously
• 2-pass imaging for small particle accuracy without compromising speed
• Routinely used globally to detect 100% of particles on PLANO and ENFSI test samples
• Image calibration sample and software ensure particles are detected the same way every run
• Automatic compensation for changes to image contrast and brightness during a run
• Accurate element identification and quantification with Tru-Q IQ algorithms, even at the highest throughput
Forensic casework, GSR screening and reporting, and light element GSR from heavy-metal-free primers when used with Ultim Extreme.
