Identification and optimization of the chemical, series of chemicals or bio-molecule that will interact with the target using impartial, expert opinion about the best equipment, services and the latest techniques
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…
