ABSTRACT:
Highly purified rare gas (helium, neon, argon, krypton, xenon, etc.) is obtained by removing impurities contained therein, such as nitrogen, hydrocarbon, carbon monoxide, carbon dioxide, oxygen, hydrogen and water, at relatively low temperatures by the use of a getter. This getter is a two-component alloy of zirconium and vanadium, or a multi-component alloy containing, as well as zirconium and vanadium, at least one of chromium, nickel and cobalt.
