The DGA-019 Analyzer enables the analysis of oxygen at ppm level in a mixture with nitrogen; the analysis is performed using a Split/Splitless injector, capillary columns and a PDID detector (Pulsed Discharge IonizationDetector).
Moreover, the gas chromatograph is configured with two valves for gas sampling and switching: two 6-port valve located in the GC auxiliary oven.
Two auxiliary gas currents are installed on the instrument to provide an He current on the PDID head and a second He current to purge the 6-port valves.
