Gas Chromatograph and Ion Mobility Spectrometer (GC-IMS)

User-friendly multi-purpose trace gas analyzer

As the exclusive North American distributor for G.A.S. Instruments, Ohio Lumex is proud to offer the Gas Chromatograph - Ion Mobility Spectrometer (GC-IMS) for use in several analytical measurements including, testing for residual solvents, impurities from production, abnormal flavor detection, ingredients authentication, odors or Toxic Industrial Chemicals (TICs) monitoring from industrial plants, cosmetics and perfume on human skin, and many more.

The GC-IMS combines the high selectivity of a chromatograph with the exceptional sensitivity (low ppbv or µg/L range) of an IMS. The option to change the polarity of the drift voltage allows the GC-IMS to detect a variety of substances, including ketones, aldehydes, alcohols, amines, sulfates and phosphorous organics, as well as halogenated compounds.
