Chemical analyzer hits the road. (Tech Talk).

SensIR Technologies, of Danbury, Conn., has developed a compact, portable chemical analyzer, called the TravelIR. Alan Rein, the company's vice president, explained that, after a chemical spill, the analyzer can take a sample of the material and match it to an internal database of thousands of compounds. If it finds a match, the identity is displayed.

Current users include the FBI; Bureau of Alcohol, Tobacco and Firearms; Drug Enforcement Agency; Agriculture Department; Argonne National Laboratory; Aberdeen Proving Ground, and U.S. and Canadian Customs.

The TravelIR uses mid-infrared spectroscopy to cover the "fingerprint" region of the electromagnetic spectrum, Rein explained. It is called the fingerprint, because the information provided is highly specific to the structure of a compound.
