Entegris GateKeeper® HGU Heated Getter Gas Purifiers

Point-of-use (POU) gas purification ensures consistent and repeatable process performance, isolates critical process areas from house gas distribution systems, and protects against gas purity upsets and cross contamination.
Provides the most complete removal of impurities for rare gases, nitrogen, and hydrogen, with high reliability, low cost, and high performance. Outlet impurity levels for O2, H2O, CO, CO2, H2, CH4, and N2 (from rare gas only) are reduced to low parts per billion (ppb) levels or below.
The heated getter material forms irreversible chemical bonds with any oxide, carbide, and nitride impurities.
Optimized design provides sub-ppb performance, which is better than gas from cylinder or liquid sources, in small footprints with max flow rates from 0.2 slpm up to 150 slpm (9 Nm3/hr).
Available in 110 – 120 VAC or 220 – 240 VAC.

Gas purified: Nitrogen, Helium, Argon.
Flowrate 20 to 200 sccm.
Small and economical purifier for Gas Chromatography (GC) and other low flow analytical applications with critical carrier gas purity requirements.
Standard voltage heater (no control unit) with virtually no maintenance.

Gas Purified: Nitrogen, Helium, Argon, Xenon.
