  • Speedy ROI – produce better than 99.9999% purity from a 99.995% cylinder
  • Provide point-of-use gas purification of helium, hydrogen, methane, nitrogen, carbon dioxide, or air
  • Reduce gas impurities from high PPM to low PPB levels
  • Decrease baseline noise and increase GC/MS sensitivity
  • Replace three traps with one purifier

Gas purification is critical to GC performance. Several types of contaminants are detrimental - notably moisture, hydrocarbons, and oxygen. VICI Metronics gas purifier modules are designed to be placed in-line with the GC carrier or detector gas supply to remove these contaminants from the analytical gases prior to their entering the GC.

VICI Metronics gas purifiers dramatically reduce contaminant levels and absorb a greater variety of contaminants than other gas purification products. Purification is optimized with a multiple bed format. Each bed functions at a lower contaminant concentration, resulting in a series of contaminant concentration gradients across the length of the gas purifier. (See illustration)

Advanced materials and design features guarantee that the modules will produce gases that are at least a factor of ten higher than a 99.9999% "chromatography grade" cylinder of gas when the purifier is supplied by a 99.995% cylinder. The cost difference between the two grades of gas will pay for the cost of the gas purifier several times over during its operating life!
