Standard Test Method for Primer Gunshot Residue Analysis by Scanning Electron Microscopy/Energy Dispersive X-Ray Spectrometry
ASTM E1588-25
Organization:
ASTM - ASTM International
Year: 2025
Abstract: 5.1 This test method is intended to be used by forensic laboratory personnel who are involved in the analysis of pGSR stubs by SEM/EDS (1, 5). 5.2 SEM/EDS analysis of pGSR is a non-destructive method that provides (6, 7) both morphological information and the constituent elements detected in individual particles. 5.3 Particle analysis contrasts with bulk sample methods, such as atomic absorption spectrophotometry (AAS) (8), neutron activation analysis (NAA) (9), inductively coupled plasma atomic emission spectrometry (ICP-AES), and inductively coupled plasma mass spectrometry (ICP-MS), where the sampled material is dissolved or extracted prior to the determination of total element concentrations, thereby sacrificing size, shape, and individual particle identification. 5.4 Automated analysis of pGSR involves some portion of the data collection being controlled by instrument software. The extent to which the SEM and EDS systems communicate and are integrated varies according to the manufacturers and the capabilities of the hardware/software.

| scope | 1.1 This test method covers the analysis of primer gunshot residue (pGSR) 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 specimen for candidate particles that could be associated with pGSR. Manual control of the instrument is then used to perform confirmatory qualitative analysis and classification of the candidate particles. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 This standard cannot replace knowledge, skills, or abilities acquired through education, training, and experience (Practice E2917), and is to be used in conjunction with professional judgment by individuals with such discipline-specific knowledge, skills, and abilities. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. | |
