New Test Method for Identification of Compounds Related to Organic Gunshot Residue (OGSR) by Liquid Chromatography-Mass Spectrometry (LC-MS)

1. Scope

This standard covers the qualitative analysis of extracts using liquid chromatography-mass spectrometry (LC-MS) to identify compounds related to organic gunshot residue (OGSR).


centralite, diphenylamine, nitroglycerin, nitrotoluene; Akardite


Gunshot residue (GSR) examination is typically performed to determine if an object was exposed to firearm discharge. GSR analysis has historically relied upon the detection of IGSR, as described in Practice E1588, which originates primarily from the ammunition primer (pGSR). OGSR analysis provides information which complements pGSR analysis and currently there are no ASTM standards using LC-MS for OGSR analysis.

The title and scope are in draft form and are under development within this ASTM Committee.
