The discharge of a firearm expels microscopic particles called gunshot residue (GSR) over nearby surfaces, including hands, clothing and the surroundings. Ordinary methods for detecting GSR such as Scanning Electron Microscopy with Energy Dispersive X-ray Spectroscopy (SEM-EDS) provide highly detailed elemental analysis but typically require specialised facilities and significant time, which can delay investigations by hours or even weeks. To solve this problem, Applied Spectra offers the J200 CX Mobile LIBS Instrument, which offers rapid, portable and accurate detection and analysis of GSR in both laboratory and external settings.
Laser Induced Breakdown Spectroscopy (LIBS) analyses materials by turning a small sample into plasma for optical emission spectroscopy. Compared to other methods, LIBS is very fast (less than a second per point in some cases) and can perform analysis with minimal or no sample preparation. LIBS also benefits from being minimally destructive, allowing further testing to be performed on a sample.
The J200 CX LIBS offers high sensitivity and accuracy, reliably differentiating GSR particles from the background - a recent study demonstrated 98.8% accuracy in detecting GSR elements (lead, barium and antimony). Its six-chambered design minimizes the risk of cross-sample contamination and its enhanced imaging capabilities and fast analysis speed produce results rapidly in the field.
