Our high performance gas purifiers includePOU(Point-of-Use) gas purifier, getter-based gas purifierand in-situ regeneration gas purification system which use catalyst/adsorber and getter technologies designed specifically to provide ultra-high purity bulk gases, such as Nitrogen,Argon, Helium, Hydrogen, Oxygen and so forth, andspecialty gases, such as Hydride Gas, Carbon Dioxideand so forth. The 9NP series gas purifiers can remove impurities such as H20, 02, CO, CO2, H2, CH4.NMHC, etc. to less than one part-per-billion(ppb) at flow rate from 1 slm to 20000Nm3/h.
