Aberdeen Proving Ground, MD — Researchers at the U.S. Army’s Combat Capabilities Development Command Chemical Biological Center (DEVCOM CBC) have helped improve technology that could give our Soldiers a forensic advantage by detecting minuscule traces of chemicals left behind by adversaries in the field.

The new technology prototype is called the Portable Chemical Fingerprint Identification System (PCFIS). The Center’s Spectroscopy Branch developed the system in partnership with Pendar Technologies, a technology startup company located in Cambridge, Massachusetts. The PCFIS is a small, automated device that can detect chemicals with very low concentration — even substances pulled from a fingerprint.
