Arrowhead is pleased to offer ISid-2 second generation advanced gunshot residue binary test kits. This kit includes everything required to collect GSR evidence from a suspect for both the investigation and for the crime lab. The new design incorporates standard “sticky tab” carbon tape particle collection devices, which meet the requirements of most state crime labs that conduct SEM (scanning electron microscope) testing for GSR. The investigator first sticky tab swabs the suspect according to approved techniques, and then places the tabs into an evidence envelope with evidence tape for delivery to the forensic laboratory. The investigator then dry swabs the suspect with the L.E.T. swab and applies a chemical reagent. A blue reaction on the swab at the 5 min. interval indicates the presence of nitrocellulose. A blue reaction is considered highly probable the suspect has recently fired a weapon. With this new kit, field results can be confirmed in the lab via SEM.
