On-Target Analysis of Gunshot Residue

By | News & Updates | No Comments

One of our customers recently used On-Target cards to analyze gunshot residue on shell casings and sent us the results! The residue tested strongly positive for copper and zinc (likely from the shell casing or bullet) had a slight positive for iron, and tested negative for cadmium and aluminium. Thanks to our On-Target users who send us interesting applications of how they have used the On-Target technology!

Have you, or would you like to, analyze something interesting with On-Target tech? Let us know! We love to hear the clever ways people utilize our tests!
