Palladium Hydrogen Purifiers - PS7-PD1 (50 - 1,085 slpm)
SAES Pure Gas Palladium Hydrogen Purifiers produce the purest hydrogen on the planet. The patented Micro-Channel design offer the most significant innovation in hydrogen gas purification in over 20 years. The advanced Hydrogen purifier offers higher flow capacity with lower cost and improved durability for high-volume manufacturing processes. SAES Pure Gas Hydrogen purifiers deliver 9N's (99.9999999%) purity with typical levels.
The PS7-PD1 includes one Palladium cell in a compact enclosure for a wide range of flows for point-of-use purification for single process tools or bulk gas supply for many process tools at large LED and semiconductor fabs. A single Palladium cell purifiers the entire inlet Hydrogen flow. The enclosure is suited for installation near the process tools or in a bulk gas room.

Palladium Membrane Diffusion - How it Works
Purification of hydrogen by palladium (Pd) membrane diffusion is the accepted technology for applications requiring part-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, only hydrogen atoms readily diffuse through the membranes. No other impurities can diffuse through the palladium membrane.
Impurities including H2O, O2, CO, CO2, N2, He, Ar, and THC (Total Hydrocarbons including CH4) impurities 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 breakthrough as compared to catalysts and getters that rely on chemical reactions on reactive surface areas. A nitrogen purge system is included to purge the purifier at startup and during any shutdown.
