Detection of Gunshot Residues Using Mass Spectrometry [PDF]

BioMed Research International, 2014
In recent years, forensic scientists have become increasingly interested in the detection and interpretation of organic gunshot residues (OGSR) due to the increasing use of lead- and heavy metal-free ammunition. This has also been prompted by the identification of gunshot residue- (GSR-) like particles in environmental and occupational samples. Various

Prevalence of organic gunshot residues in police vehicles [PDF]

Science & Justice, 2020
The present study investigated the organic gunshot residue (OGSR) background level of police vehicles in Switzerland. Specimens from 64 vehicles belonging to two regional police services were collected and analysed by LC-MS in positive mode. The driver's and back seats were sampled separately to monitor potential differences between locations and to ...
