HID/PDD

  • Non-radioactive, non-destructive, highly sensitive, and universal
  • Linear response over a wide range
  • Minimum detectable quantities for most compounds in the low ppb range

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.
