VICI Pulsed Discharge Detectors
The pulsed discharge detector (PDD) utilizes a stable, low-powered, pulsed DC discharge in helium as the ionization source. Performance is equal to or better than GC detectors with conventional radioactive sources.
The D-2 is a dual mode, universal detector system which can be retro-fitted to your older GC. The D-2-I is optimized for trace level work in the helium photoionization mode.
The stand-alone systems include detector, controller, electrometer, helium purifier, and power supply.
Available for 110 VAC and 220 VAC.
