Organic GSR Analysis for Potential Shooter Determination

Organic GSR Analysis for Potential Shooter Determination


May 2015


Through the National Institute of Justice (NIJ) Forensic Technology Center of Excellence (FTCOE), West Virginia University (WVU) evaluated emerging approaches for the detection of gunshot residue (GSR) based on organic materials in the residue. One instrument was evaluated for screening for elemental constituents. This study examined x-ray fluorescence (XRF, a portable instrument), ion mobility spectrometry (IMS), and mass spectrometry.

Funding for this Forensic Technology Center of Excellence report was provided by the National Institute of Justice, Office of Justice Programs, U.S. Department of Justice.
