Palladium Hydrogen Purifiers - PS7-PD05 (0 - 50 slpm)SAES Pure Gas micro-channel palladium purifiers produce ultra-high-purity hydrogen (99.9999999%). All purifiers use patented micro-channel palladium membrane technology to remove all impurities to parts-per-trillion levels. The compact PS7-PD05 purifier is ideal for low flow rate university, laboratory, and industrial applications. The hydrogen purifier can be installed downstream of compressed cylinders or generators.
How it Works Purification of hydrogen by palladium (Pd) membrane diffusion is the accepted technology for applications requiring parts-per-billion gas purity. Palladium acts as a catalyst, causing hydrogen gas molecules to dissociate into atoms upon contacting the membrane surface. The atoms are small enough to diffuse through the palladium membrane, driven by differential hydrogen pressure across the membrane. The hydrogen atoms recombine into molecules after passing through the membrane. Hydrogen purifiers operate at approximately 400°C. At this temperature, hydrogen atoms readily diffuse through the membranes. No other material can diffuse through palladium and so the permeate is only hydrogen. Impurities including H2O, O2, CO, CO2, CH4/THC, N2, He, and Ar remain on the inlet side of the membrane and are continuously purged through a bleed connection. The unique properties of palladium provide a solid barrier with no breakthroughs as compared to catalysts and getters that rely on chemical reactions on reactive surface areas. Key Features
