HELIUM-PURIFICATION UNIT FOR HIGH-PURITY INERT-ATMOSPHERE BOXES
A device for purifying and recycling the helium atmosphere of two dry boxes having a combined volume of 50 ft/sup 3/ is described. Trace impurities are removed by passing the helium through a palladium-catalyst container and a molec ular sieve bed and cooling to - 195 deg C before passing through an activated charcoal bed. Flow rates of 10 scfm and purity levels are estimated. Regeneration procedures are given. Construction prints and a schematic diagram of the heliumpurification unit are shown. (H.G.G.)
