GUARDION is hand-portable and ruggedized for use in a hot zone or extreme environments. The CUSTODION™, a solid phase microextraction (SPME) fiber syringe, is used for simple sample collection. It can analyze 12-15 samples per hour.

GUARDION includes CWA and TIC libraries as well as a hazards database for rapid decision support and can operate from a single battery charge for up to 3 hours.

The GUARDION vacuum system includes a ruggedized, low-maintenance turbomolecular pump that does not need to be replaced. The direct GC to MS interface eliminates the need for bake-out, minimizing logistical burden.

GC/MS is considered the “gold standard” for chemical identification. This technique can identify single or multiple substances within complex samples. Additionally, it can identify trace compounds that can go undetected by other technologies. Can be used in conjunction with the NIST/EPA/NIH mass spectral library.
