GSR Kit SEM
The SEM examination supplies consist of metal discs (1/8" stub, 1/2" face) with adhesive on them. The discs are dabbed on the hands and the adhesive picks up the gunshot residue particles. The metal discs are then sent to the laboratory. Visible stains do not appear on the hands. The resulting data is obtained only by laboratory examination.

Colorado GSR Kit
The examination of gunshot residue can disprove an assumption made falsely or mistakenly. For example, in the case of an apparent suicide involving a handgun, a gunshot residue collection should be done on the hands of the deceased. If no residue is found, the case could actually be a murder made to look like a suicide.

These kits are the Gunshot Residue (GSR) test kits specifically for the State of Colorado. The Denver GSR Kit is specifically for the City of Denver, Colorado.
