High sensitivity VICI PDDs for reliable detection in Agilent GC systems.
For sale are refurbished VICI PDDs (pulsed discharge detectors) designed to integrate seamlessly with Agilent gas chromatography systems. These detectors are also compatible with other GC brands. We supply essential VICI parts, consumables, and refurbished components for VICI detectors. Each product is rigorously tested and comes with a warranty for your peace of mind.
We operate independently, not as agents or resellers. Our entire inventory is ready for immediate shipment and can be installed by our qualified service engineers. Warranty is included for all systems.
VICI PDDs employ a stable, low-power pulsed DC discharge in helium to enable ionization. The flowing eluants are ionized by helium discharge photons, with the resulting electrons being directed by bias electrodes toward the collector electrode. This process effectively generates quantifiable detector output with performance equal to or surpassing conventional radioactive source detectors.
In electron capture mode, PDDs are selective detectors for high electron affinity compounds such as freons, chlorinated pesticides, and other halogen compounds, with a minimum detectable quantity down to femtogram or picogram levels. These detectors operate at temperatures up to 400°C, requiring He and CH4 to be introduced upstream from the column exit.
In helium photoionization mode, the PDD serves as a universal, non-destructive, high-sensitivity detector. It provides a linear response for both inorganic and organic compounds across a wide range, and detects fixed gases with a minimum detectable quantity in the low ppb range. This mode effectively replaces flame ionization detectors in environments like petrochemical or refinery settings, where flame and hydrogen use pose challenges. Furthermore, doping the helium discharge gas with noble gases like argon, krypton, or xenon allows the PDD to operate as a specific photoionization detector, selectively determining aliphatics, aromatics, and amines.
These detectors are available for use with both 110 VAC and 230 VAC power supplies.
Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.
We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.
We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.
With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.
Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.
Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.
Two to six weeks, depending on refurbishment scope and whether calibration is included.
We ship to 38 countries. Crating and customs handling are quoted with the instrument.
Tell us what you need and a scientist finds it for you, usually within the hour.
