Agilent 7890 GC with Wasson-ECE Instrumentation, dual PDD

The Wasson-ECE 7890 Auxiliary valve and column oven provide extended functionality to the Agilent 7890 GC. The oven provides an isothermal zone for columns and up to five additional valves, such as back-flush and gas sample valves. The auxiliary oven allows applications such as the refinery gas analyzer to analyze complex streams by multi-dimensional chromatography.

Wasson-ECE Instrumentation is the leader in custom configured GC analyzers. Wasson-ECE Instrumentation offers hardware only solutions for customers with chromatography experience who would prefer to develop their own analytical methodology. They offer flexible equipment to ensure that their systems will work with your proprietary methods.

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.

• 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
