GateKeeper® Inert Gas Purifiers

Cost-effective, environmentally friendly gas purification
Data Sheet (926925)
MSDS (45555)
 
GateKeeper® Inert Gas Purifiers
  • Consistently delivers ultrapure gas
  • Designed for use with N2, He, Ne, Kr, Xe, Ar, halocarbons and light hydrocarbons. The purifiers remove O2, H2, CO, CO2 and H2O to sub-ppb (part-per-billion) levels; SO2 to sub-ppt (part-per-trillion) levels.
  • Guards against bulk gas purifier breakthrough, impurity spikes from liquid storage tanks, cylinder changeouts and unexpected contaminants in the process
  • Does not release hydrocarbons that may contaminate the process
  • Uses ambient temperature purification technology – no power or heat required
  • Low pressure drop across purifiers
