Gas purity is essential in any application requiring extreme sensitivity. Contaminant traps and gas purifiers for specific gases dramatically reduce the levels of contaminants, enhance the purity of lower grade helium, and help insure instrument stability, reproducibility, and lower maintenance costs.

Gas Purifiers from VICI Metronics

Gas purifiers for specific gases
Designed to go in-line with the carrier or detector gas supply, these gas purifier modules dramatically reduce contaminant levels in helium, hydrogen, nitrogen, or air. This line includes original equipment gas purifiers for the Agilent Mass Spec and LC Mass Spec.
Additional specialized purifiers:
   • Nitrogen purifier for LC/MS
   • Purifier for nitrogen generators
   • Purifier for chemical ionization MS

Contaminant traps
Contaminant traps remove moisture, hydrocarbons, oxygen, mercury, or sulfur, for those applications with only one specific contaminant of interest.
   • Moisture traps
   • Hydrocarbon traps
   • Oxygen traps
   • Mercury traps
   • Sulfur traps

Carbon dioxide gas purifiers
Optimized for the high flows of process equipment, these modules significantly outperform carbon-based hydrocarbon traps.

Liquid carbon dioxide purification
Our new CO₂ purification technology (patent pending) takes Coleman grade CO₂ and produces SFC/SFE grade CO₂ at the point of use, for a significant cost savings.

Helium and nitrogen purifiers from VICI Valco Instruments

Our 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.
