Product Information GUARDION

The GUARDION uses a fibre syringe and needle traps for simple sample collection and can analyse 12-15 samples an hour.

It 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 three hours.

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

The GUARDION’s vacuum system includes a low-maintenance turbomolecular pump that does not need to be replaced. The direct GC-to-MS interface allows for rapid elution of low-vapour-pressure compounds.
