The newest member of the PDD family is also the smallest and thriftiest. The miniPDD uses about one fifth (20%) the amount of helium as the D-3 and D-4 versions, giving up only a bit of sensitivity and dynamic range in return. It is approximately one half the size of the D-4, but has nearly the same sensitivity — about 100 ppb for fixed gases. With its reduced size, weight, and helium consumption, it is particularly well sui…
VICI introduces the GC detector where the PDD (pulsed discharge detector) utilizes a stable, low-powered, pulsed DC discharge in helium as the ionization source. The D-2 is a dual mode, universal detector system which can be retrofitted to your older GC. The D-2-I is a helium photoionization detector, optimized for trace level work with packed columns. The stand-alone systems include detector, controller, electrometer, helium…

The D-3 is optimized for trace level work in the helium photoionization mode, and utilizes the electronics and power supply of the host GC. Model D-5 is optimized for electron capture detection. Available for 110 VAC and 230 VAC.
Model D-5 is a pulse discharge GC detector designed for plug-and-play installation on the Agilent 6890. The D-5 is optimized for trace level work in the electron capture mode, and utilizes the electronics and power supply of the host 6890. Model D-3 is optimized for helium photoionization detection. Available for 110 VAC and 230 VAC.
Model D-4 a GC Detector available in versions for easy installation on most of the GC's in current use, including the Varian 3800, Shimadzu 14 and 17, ThermoFinnigan Trace, Mega, and Top, and Hewlett Packard 5890. The D-4 is single mode, optimized for trace level work in the helium photoionization mode. Available for 110 VAC and 230 VAC.
Model D-6 is a single mode GC detector, optimized for trace level work in the electron capture mode. IT is available in versions for easy installation on most of the GC's in current use, including the Varian 3800, Shimadzu 17, ThermoFinnigan Trace, Mega, and Top, and Hewlett Packard 5890. Available for 110 VAC and 230 VAC.
Reduced breakdown liners Our improved injection port liner reduces breakdown of endrin and DDT during injections while increasing the interval between liner changes. The problem DDT and Endrin are easily degraded in the injection port; with non-deactivated liners and those filled with non-deactivated glass wool, Endrin breakdown can be as high as 98%. EPA method 8081A states "If degradation of either DDT or Endrin exceeds 15%,…
VICI AG uses proprietary liquid phase processing to produce low bleed characteristics while maintaining identical retention characteristics to the phases you are used to. These processes combined with proprietary coating, curing, bonding, and crosslinking produce MS-certified bleed characteristics equal to the best. Improved upper temperature limits enhance column "bake out", reducing sample carryover and cycle times. ValcoBon…
Now you can reduce run time, faster than micropacked, by replacing your packed columns with ValcoPLOT HayeSep capillary PLOT columns, with phases available only from VICI. Our proprietary phase processing produces the first capillary PLOT columns with characteristics identical to HayeSep packed columns. The ValcoPLOT line also includes Molesieve and Alumina PLOT columns. Visit VICI AG website to veiw now.
Permeation tubes are small, inert capsules containing a pure chemical compound in a two phase equilibrium between its gas phase and its liquid or solid phase. They are used to generate a stable concentration of a specific trace chemical. At a constant temperature, the device emits the compound through its permeable portion at a constant rate. They are typically inserted into a carrier flow to generate test atmospheres for c…
Patented G-Cal permeation tubes offer a proven and repeatable means of generating a desired gas or vapor concentrations. The permeant gas escapes through the proprietary membrane system and mixes with a carrier gas (nitrogen is the most common) at a controlled flow rate to obtain a known mixture in ppm or ppb. Applications include calibration of gas monitoring systems and chromatographs, accuracy check of gas detectors, and ge…
Ultra-high capacity for the contaminant of interest; either Moisture, Hydrocarbons, Oxygen, Sulfur and Mercury. For applications with a single contaminant of interest, high capacity contaminant specific traps are your best option, since they generally have four times as much capacity for the specific contaminant as a purifier. This translates to a capacity that exceeds twelve standard type "A" tanks of gas or the equivalent of…
VICI AG heated helium purifier provides point-of-use purification of helium or other noble gases, such as Ar, Ne, Kr, and Xe, to sub-ppm levels of reactive gaseous impurities, removing even nitrogen and methane. The nitrogen purifier is similar, purifying nitrogen to sub-ppm levels of gaseous impurities. The miniature version of each purifier is designed to be installed in a GC’s flow path immediately upstream of the injector.…
Gas purifiers for specific gases designed to go in-line with the carrier or detector gas supply, these gas purifier modules dramatically reduce contaminant PPM levels in helium, hydrogen, nitrogen, or air. They decrease baseline noise and increase GC/MS sensitivity and replace three traps with one gas purifier.This line includes original equipment gas purifiers for the Agilent Mass Spec and LC Mass Spec. Additional specialized…
Syringes used to fill a loop on a sample injection valve have blunt, smooth ends. The end of the needle must contact the bottom of the valve’s fitting detail uniformly and seal on the outside of the tip to deliver sample with any repeatability. All VICI Precision Sampling syringes for valve injections have smooth, burr-free ends that fit the valve fitting details perfectly. The standard HPLC syringe is our basic C-160 with a 2…

Hollow, flow-through plunger with integrated 3-way valve designed for liquid and gases, with a push button on/off valve at the front end. The new Precision Sampling hollow plunger syringe with two integrated valves opens a whole new world of application possibilities: Dispense a viscous sample more easily by introducing it into the rear of the syringe instead of drawing it up through the needle. Eliminate sample-to-sample cros…
The Dual Layer PEEK tubing eliminates any concern that a critical sample stream could be contaminated by pigments used to color code the tubing. The pigmented layer surrounds a separate but integrally-bonded inner layer of natural PEEK. The 1/16" OD tubing is available in standard sizes, or in OEM quantities with any ID you specify, from .002" to .030". The ID tolerance of ±.001" is equivalent to or better than that of tubing…
