VICI’s Pulsed Discharge helium ionization Detector (PDD) extends the detection capabilities of the popular Agilent 6890 and new 7890 gas chromatographers (GCs). The basic operating mode of the PDD can replace many of the detectors currently used by GC manufacturers.
Pulsed discharge detector Model D-3-1-HP is designed for plug-and-play installation on Agilent GCs, with models available for the 6890 and 7890. The D-3-1-HP 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 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.
The company has announced the launch of the new NovaCHROM 2000 Gas Chromatograph. The NovaCHROM 2000 GC is a culmination of years of experience in high sensitivity Gas Chromatography specific for the Continuous Analysis of Ultra High Purity Argon to ppb levels.
Month on month the gasworld website continues to be the primary portal for information, on a global scale, about our industry - be it through the provision of news and features, or information in the expansive company directory section. Launched in 2004, it is the only independent online news provider and information portal for the global industrial gas community and the larger end-user markets.
