The Series 590 GC features our patented Discharge Ionization Detector (DID) which permits analysis of trace gas impurities in the part per billion (ppb) range. Manufacturers of UHP specialty, electronic and bulk industrial gases are successfully using the Series 590 DID GC to analyze gases for ppb level of contamination.

Each Series 590 GC is custom built to a particular application. Contact us to discuss the details or your specific requirements.
