Pulse Discharge Detector Extends GC Capabilities
VICI's pulsed discharge helium ionization detector (PDD) extends the detection capabilities of the Agilent 6890 and 7890 GCs. The basic operating mode of the PDD can replace virtually any of the detectors currently used by GC manufacturers.
Pulsed discharge detector Model D-3 is designed for plug-and-play installation on Agilent GCs. The D-3 is optimized for trace level work in the helium photoionization mode, and utilizes the electronics and power supply of the host GC. The system includes detector cell, pulser and FID board, plus standard and mini helium purifiers to provide the best sensitivity. It is suitable for use with columns from 50-µm capillaries to 1/8" packed.
The detector 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 detector is a suited upgrade for FIDs in petrochemical environments. When the helium discharge gas is doped with a suitable noble gas, the PDD functions as a lampless, windowless photoionization detector.
