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.
The HP 6890 Series gas chromatograph system delivers unprecedented levels of performance, convenience, productivity, and eases regulatory compliance. It features electronic pneumatics control of all gas pressures and flows. Onboard sensors automatically compensate for ambient temperature changes and barometric pressure differences to routinely achieve more accurate and reproducible results.
This Agilent G1530A GC with PDD Pulsed Discharge Detector is in good condition. It has been tested here at SpectraLab Scientific.
A 90-day warranty is included.
