Firearm residue analysis kit (10 tests/box)

Atomic Absorption Spectroscopy is the most effective and sensitive analytical method for the detection of firearm discharge residue on the skin or clothing of a suspect. The AAS process has demonstrated its suitability as an investigative aid for nearly a decade and has been accepted in federal and state courts as conclusive evidence in numerous cases.

This methodology detects the presence of Barium, Antimony, Copper and Lead. Barium and Antimony are present in the primers of most american and european brands of ammunition, while Copper and Lead particles originated from cartridge cases and projectiles. Upon detonation of a cartridge, these elements are deposited on the shooter's hands.

TDF16 is used to swab the entire surface of the suspects hands.
