The GasID, from Smiths Detection, is a portable gas and vapor identifier using Fourier Transform Infrared Spectroscopy, or FT-IR, to measure how gas and vapor samples interact with infrared light. Each gas has its own unique infrared fingerprint, which when analyzed by the GasID, is instantly compared against an onboard database to provide the identity of the unknown gas or vapor. Database libraries include: Toxic Industrial Chemicals, Chemical Warfare Agents, Volatile Organic Compounds, Flammables, and Non-Flammables. The GasID system is supported with 24 hours a day 7 days a week Reachback service.
