Purity: *9.***9%, *9.***5%, *9.**9%, *9, **5%, *9.*9%, *9.*5%, and *8%, etc. Helium is a colorless, odorless, tasteless, non-toxic, inert monatomic gas that heads the noble gas group in the periodic table. Helium is used in cryogenics (its largest single use, accounting for about a quarter of production), the cooling of superconducting magnets, particularly the main commercial application in MRI scanners. Helium&#**9;s other industrial uses as a pressurizing and purge gas, and a protective atmosphere for arc welding and processes (such as growing crystals to make silicon wafers), account for half of its use. Economically minor uses, such as lifting gas in balloons and airships are popularly known.
