The CWA-Analyzer is a multi-gas analyzer for the high-sensitive detection and identification of Chemical Warfare Agents (CWA) and/or Toxic Industrial Chemicals (TIC) developed by IUT/IUT Medical over more than 20 years. It is best suitable for the use in homeland security, building protection, and CBRNE application in general. It is an Ion Mobility Spectrometer (IMS) (also as GC-IMS) with high sensitivity in the lower ppb-range and with high resolution. It is also be available as GC-IMS, gas chromatographic (GC) column coupled with an IMS to enhance the selectivity and to reduce cross sensitivities available with still high sensitivity for extreme requirements.
