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. In the helium photoionization mode, the PDD is a universal, non-destructive, high sensitivity detector. In the electron capture mode, the PDD is a selective detector for monitoring high electron affinity compounds such as freons, chlorinated pesticides, and other halogen compounds.
