“…By far the most popular method of metallic GSR collection for analysis with voltammetry is cotton swabbing 10, 11, 23, 27, 29, 30.This involves soaking a cotton q‐tip with HNO 3 (usually 5 % v/v) and running the swab over the hand of the shooter. The cotton swabs are then cut from the handle and placed into a plastic vial, to which is added strong acid (usually 4 M HCl) which will leach out the metals from the swab.…”

“…The cotton swabs are then cut from the handle and placed into a plastic vial, to which is added strong acid (usually 4 M HCl) which will leach out the metals from the swab. The swab is left in the vial for times ranging from 1 h 10 to overnight with stirring 27. Other metal extraction procedures from cotton swabs include sonication 29 and ultrasound 30.…”

“…Following on from this work, in 1982 Brihaye et al. combined the detection of Pb and Sb in GSR at the HMDE with the swabbing technique of sample acquisition 27. These samples were obtained from a 7.65 caliber pistol and a 0.357 magnum revolver using HNO 3 ‐soaked q‐tips (in accordance with Briner et al.…”

Current demands for detection of Gunshot Residue (GSR) require a reliable and rapid decentralized detection system with high sensitivity and specificity. This article reviews the use of electrochemical devices for GSR detection over the last 35 years and highlights recent advances associated with the demands of GSR field detection such as portability, speed, cost and power. Anodic stripping voltammetry (ASV) has been widely implemented for the detection of the metallic components of GSR at a variety of working electrodes. Efforts toward the detection of the organic components of GSR have also been reported using cyclic-and square-wave voltammetry. The simultaneous detection of both organic and inorganic GSR constituents has recently been examined to increase the overall information content in a single voltammetric scan. As well as this, exploitation of screen-printing fabrication allows replacement of conventional electrochemical cells with easy-to-use sensor strips Sampling methods for electrochemical GSR analysis are also advancing from acid washes or swabs to simpler abrasive methods which integrate sampling and analysis obviating the need for intermediate processing steps. The latest direction of electrochemical detection of GSR involves chemometric treatment to evaluate data allowing for more objective conclusions and increasing the automation of the system. These advances indicate great promise for investigating firearm-related crimes, and bring significant changes to the detection of GSR making electroanalysis a powerful tool for decentralized forensic analysis.

“…Many other techniques have been tried, including proton -induced X -ray emission (Panigahi et al ., 1982 ), anodic stripping voltammetry (Brihaye, Machiroux and Gillain, 1982 ) and Auger electron microscopy (Hellmiss, 1987 ). For one reason or another, none ever gained any great deal of credibility.…”

“…There are several methods for qualitative and quantitative analysis of GSR. These include neutron activation analysis (NAA) [6,7], scanning electron microscopy cou-pled to energy dispersive X-ray spectrometry (SEM/ EDX) [8,9], inductively coupled plasma mass spectrometry [10], inductively coupled plasma atomic emission spectroscopy (ICP/AES) [11], flameless atomic absorption spectrometry (FAAS) [12], atomic absorption spectrometry (AAS) [13,14] and stripping voltammetry (SV) [15][16][17][18][19][20][21][22][23][24].…”

Simultaneous Determination of Antimony and Lead in Gunshot Residue by Cathodic Adsorptive Stripping Voltammetric Methods

2011

Differential pulse cathodic adsorptive stripping (DPCAdSV) and square wave cathodic adsorptive stripping (SWCAdSV) voltammetric methods were developed for the determination of antimony and lead in gunshot residues. Linear working ranges for DPCAdSV and SWCAdSV methods were (2.0 10 À9 M and 5.8 10 À10 M. Antimony and lead contents obtained by these methods in gunshot residues are in good agreement with those obtained by graphite furnace atomic absorption spectrometric method within a confidence limit of 95%.
