Sirchie AAA100 Atomic Absorption Analysis Test Kits

Atomic Absorption Analysis is considered to be a sensitive, most effective method for the detection of firearm discharge residue on the skin or clothing of a suspect. The AAA 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. The AAA process detects the presence of barium, antimony, copper and lead. Barium and antimony are present in the primers of most United States-made and some European brands of ammunition, while copper and lead particles originate from cartridge cases and projectiles. Upon detonation of a cartridge, these elements are deposited on the shooter’s hands. The AAA100 kits are used to swab the entire surface of the suspect’s hands. The samples taken are then submitted for laboratory analysis. Due to the extreme sensitivity of Atomic Absorption Analysis, the swabs, preservation tubes, nitric acid solution and container must be free from contamination. SIRCHIE has developed this kit to fulfill this requirement. The AAA100 kit contains 10 individual test kits and the components of each are handled under controlled conditions to ensure absolute minimum contamination. Sold in sets of 10 kits.
