Pittsburgh Helium (HE) Gas Supplier

Helium is the second lightest element, hydrogen being the lightest. While there is only a little over five cubic feet of helium in a million cubic feet of air, much larger concentrations are found in some natural gas wells, and these are the primary source of commercial helium.

Helium is considered chemically inert. As a gas, it is colorless odorless and tasteless and it less soluble in fluids than any other gas. As a liquid, helium is also colorless and odorless. It is extremely important in low temperatures approaching absolute zero. It has the lowest boiling point of any liquefied gas. Other gases will solidify upon contact with liquid helium.
