GUARDION utilizes high speed, highresolution gas chromatography (GC) and a revolutionary miniaturized toroidal ion trap mass spectrometer (MS) to identify volatile and semi-volatile organic compounds in complex gases, vapors, liquids and solids. GUARDION is hand-portable and ruggedized for use in a hot zone or extreme environments. Its high speed GC combined with a miniaturized toroidal ion trap mass spectrometer redefines the size, weight, and speed for hand-portable GC/MS technology. GUARDION is ready to operate within five minutes from a cold start. The CUSTODION™, a solid phase microextraction (SPME) fiber syringe, is used for simple sample collection and injection into the GC/MS system. Advanced low thermal mass GC technology enables rapid heating and cooling of the GC column, allowing 12-15 samples to be analyzed per hour.
