VICI PDDs (pulsed discharge detector) for Agilent GC-cover
VICI PDDs (pulsed discharge detector) for Agilent GC

For sale: Refurbished VICI PDDs (pulsed discharge detector) on Agilent GC Also available: Detector f (more)or other GC brands VICI parts and consumables Refurbished parts for VICI Detectors All our products are fully tested and delivered with warranty     We are not a agent/reseller. All products on our website are in stock and can be delivered with installation by our own service engineers. All systems are delivered with warranty!   VICI PDDs (pulsed discharge detectors) utilize a stable, low powered, pulsed DC discharge in helium as an ionization source. Eluants from the column, flowing counter to the flow of helium from the discharge zone, are ionized by photons from the helium discharge. The bias electrode(s) focus the resulting electrons toward the collector electrode, where they cause changes in the standing current which are quantified as the detector output. Performance is equal to or better than detectors with conventional radioactive sources. 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. For this type of compound, the minimum detectable quantity (MDQ) is at the femtogram (10-15) or picogram (10-12) level. The PDD is similar in sensitivity and response characteristics to a conventional radioactive ECD, and can be operated at temperatures up to 400°C. For operation in this mode, He and CH4 are introduced just upstream from the column exit. In the helium photoionization mode, the PDD is a universal, non-destructive, high sensitivity detector. The response to both inorganic and organic compounds is linear over a wide range. Response to fixed gases is positive (increase in standing current), with an MDQ in the low ppb range. The PDD in helium photoionization mode is an excellent replacement for flame ionization detectors in petrochemical or refinery environments, where the flame and use of hydrogen can be problematic. In addition, when the helium discharge gas is doped with a suitable noble gas, such as argon, krypton, or xenon (depending on the desired cutoff point), the PDD can function as a specific photoionization detector for selective determination of aliphatics, aromatics, amines, as well as other species. Available for 110 VAC and 230 VAC.

Tekmar Dohrmann Velocity XPT Purge and trap-cover
Tekmar Dohrmann Velocity XPT Purge and trap

For sale: Tekmar Dohrmann Velocity XPT Purge and trap Condition: never used Including: installation  (more)kit + test reports from manufacturer     We are not a agent/reseller. All products on our website are in stock and can be delivered with installation by our own service engineers. All systems are delivered with warranty! ​Velocity XPT is more than a next-generation Purge and Trap system, it’s a revolutionary leap in technology. Advancements in Velocity XPT ensure the highest throughput with the least amount of downtime. From cutting sample cycle time nearly in half, to built-in intelligent diagnostics, Velocity XPT is the most productive Purge and Trap available today. With the Velocity XPT, you increase the sample throughput up to 100%. This nearly double sample throughput and increases the profitability of your VOC lab without the cost of an additional GC system. Patent-pending Accelerated Purge and Trap technology lets you independently control the flow rate during all modes, greatly reducing dry purge and bake times. Velocity XPT also provides a 25% reduction in trap cool down time after bake mode. Forward Focusing Chamber:  This patent-pending technology provides the highest resolution chromatography and superior peak shape for early eluting gases. By placing an expansion chamber after the trap during the desorption modes, analytes are focused into a tight band. When analytes are tightly focused prior to desorption into the GC, dramatic improvements in chromatography resolution are evident. The FFC also efficiently desorbs which greatly reduces carryover from run to run. Exceptional Inertness: Silcosteel tubing and Silcosteel-treated fittings throughout the sample pathway prevent loss of active, polar, and high-boiling compounds, and also resists corrosion. With the simple setup and accurate control, you save time by entering all parameters electronically with Electronic Flow Control where flow and pressure parameters remain precisely the same and are constantly monitored for accurate and reproducible results. Automatic Leak Check, Electronic Pressure Monitor: With intelligent diagnostics, Velocity XPT quickly and simply checks itself for leaks. If a leak is detected, system diagnostics help you isolate and pinpoint leaks. The Electronic Pressure Monitor uses a pre-set over pressure limit to identify potential pressure build ups and will shut itself down before damage can occur. The Guardian Foam Sensor option is a set of built-in photodiode-based sensors. If foam or liquid is detected at the top of the glassware, purge gas shuts down, the vent valve closes, and the sample drains. Guardian can be configured to automatically add an anti-foaming agent to the sample, allowing purge to continue and without re-running the sample.

Perkin Elmer Inc. – HGA-900 Graphite furnace The HGA ® 900 for the AAnalyst 400 is the latest in advanced furnace designs from PerkinElmer, the world’s leading supplier of graphite furnace systems. The HGA 900 applies the latest advances in graphite furnace technology for unparalleled performance, flexibility and ease-of-use. The HGA 900 is controlled by the powerful, easy-to-use PerkinElmer WinLab32™ for AA software. The unique mounting arrangement makes the change from furnace to flame operation (or vice versa) extremely easy. The PerkinElmer HGA Massman-type graphite furnace design used in the HGA 900 has proven its capabilities in tens of thousands of laboratories worldwide. With the HGA 900 you don’t have to worry about variations in input line voltage affecting the performance of your furnace. A state-of-the-art power supply monitors and compensates for line variations, providing heating rates independent of input line voltages (208-240V). The result is heating rates greater than 2000 °C/s, providing the highest degree of freedom from interferences and the most reproducible characteristic mass values of any furnace available – any day, anytime. Unlike other furnace systems, with the HGA 900, tube temperatures are virtually independent of graphite tube electrical resistance resulting in consistent, repeatable temperatures and performance. The HGA 900 features the patented PerkinElmer graphite tube with integrated platform – the most significant improvement in platform atomization in the last two decades.
