Ferrotraceis an iron image detection spray that reveals invisible iron traces left on a suspects hands after touching a weapon. Ferrotrace offers superior sensitivity, convenience and ease of use over other currently available field tests.
Even after a weapon (gun, knife, hand grenade) has been removed from the crime scene (or destroyed), an officer can quickly screen a large number of suspects by spraying Ferrotrace directly onto hands, palms, fingers or environmental surfaces such as paper. If the suspect was in contact with the weapon containing iron elements, the invisible iron traces will turn a dark violet color. Positive reactions appear only from touching iron which is uncoated. Ferrotrace is non-toxic.
