2020年5月22日 · 1.1 This practice covers the analysis of gunshot residue (GSR) by scanning electron microscopy/energy-dispersive X-ray spectrometry (SEM/EDS). The analysis is performed using automated software control of both the SEM and EDS systems, to screen the sample for candidate particles that could be associated with GSR.

The integration of SEM into GSR analysis elevates the accuracy, reliability, and efficiency of forensic investigations. Automation further enhances this method by enabling consistent, high-throughput analyses while adhering to global standards. For forensic laboratories and law enforcement agencies, SEM represents a powerful tool for uncovering ...

2025年2月28日 · This article explores, through a narrative review, the application of SEM techniques in GSR analysis to clarify the methodological approaches supporting effective forensic investigations, highlight the advantages and limitations of SEM, and enhance the accuracy of GSR particle identification.

2015年7月1日 · Gunshot residues are collected after shooting sessions using tamponnoirs to determine the composition of the GSR reference by various techniques to choose methods and techniques most suitable for this type of analysis, such as scanning electron microscopy coupled with X-ray microanalysis (SEM/EDX) (Gilchrist et al., 2012, Lopez-Lopez et al ...

2022年5月11日 · 1.1 This practice covers the analysis of gunshot residue (GSR) by scanning electron microscopy/energy-dispersive X-ray spectrometry (SEM/EDS). The analysis is performed using automated software control of both the SEM and EDS systems, to screen the sample for candidate particles that could be associated with GSR.

The Thermo Scientific Phenom Perception GSR Desktop SEM is the only dedicated SEM specifically designed for gunshot residue analysis. Because the system is automated, it enables you to speed up the analysis process. With no need to change your settings each time, you can immediately focus on the task at hand.

Particle analysis, specifically Pb, Ba, and Sb, by SEM and EDS is the most powerful forensic tool that investigators use for gunshot residue (GSR) analysis. Meticulous collection, analysis, and interpretation of material obtained from crime scenes are imperative in ensuring accurate evidence is presented during legal proceedings.

AZtecGSR is a dedicated tool for the detection and analysis of gunshot residue (GSR) particles in the SEM. AZtecGSR is a tailored version of the AZtecFeature particle analysis platform, sitting within the AZtecLive NanoAnalysis suite, and which is fully optimised for GSR analysis including classification and reporting to the 2016, 2017 and 2020 ...

2024年10月15日 · SEM-EDX analysis confirmed the presence of GSR components in the sample, lacking concentration details. FRET analysis involving Acf and RhB dyes provided insight into individual component concentrations, particularly effective at higher Sb +3 concentrations (around 500 µg/L to 550 µg/L).

This guide covers the analysis of primer gunshot residue (GSR) by scanning electron microscopy/energy-dispersive x-ray spectrometry (SEM/EDS) by automated and manual methods. It makes recommendations concerning interpretation and report writing, contamination issues, expert witness testimony, and training.
