For medical, research and analysis applications

Helium is abundant in the Sun's atmosphere but is found at trace levels in the Earth's atmosphere.

However, helium can  also be found in fossil form in natural gas pockets in some oil fields, where it is extracted by drilling deep into the subsoil of certain regions in the U.S.A., Poland, Russia, Algeria and Qatar.

Helium is an extremely light gas (its density is 0.169 kg/m3) and is therefore very volatile. It is colorless, odorless, non-flammable and completely inert.

Air Liquide supplies this pure specialty gas in different volumes, depending on your needs.
