General Description
Based on leading IMS technology, the LCD-NEXUS is a portable, compact and rugged chemical warfare agent (CWA) and toxic industrial chemical (TIC) gas and vapour detector. Suitable for fixed or moving platforms, the LCD-NEXUS provides highly sensitive and selective detection, capable of measuring chemical concentrations down to miosis levels with accurate discrimination. The LCD-NEXUS simultaneously samples for traces of CWAs and TICs, to provide real-time warning for threats at or below immediately dangerous to life and health (IDLH) levels. It also provides chemical details including class, type, concentration and dosage as well as CWA identification.
Technical Description
LCD Nexus employs dual ion mobility spectrometry technology.
