Pulse Discharge Detector



VICI's Pulsed Discharge helium ionization Detector (PDD) extends the detection capabilities of the popular HP 6890 GC. The basic operating mode of the PDD can replace virtually any of the detectors currently used by GC manufacturers.

The D3-1-HP Detector is specific for the HP 6890 GC. It uses the standard 6890 detector hardware and includes the HP electrometer. It is literally plug-and-play. It can take the place of an existing detector or it can be placed in an unused position. It even includes the acclaimed Valco Helium Purifier to provide the best possible sensitivity. It is suitable for use with columns from 50 micron capillaries to 1/8" packed.

The PDD is non-radioactive, non-destructive, highly sensitive and universal. Response is linear over a wide range, and MDQs for most compounds are in the low ppb range. With no open flame, no hydrogen requirement and close-to-true-mass response, the PDD is the ideal upgrade for FIDs in petrochemical environments. When the helium discharge gas is doped with a suitable noble gas, the detector functions as a lampless, windowless photoionization detector.
