Helium

Helium (He)

Is a colourless, odourless, non-toxic, non-corrosive and non-combustible gas. It is mainly sourced from natural gas wells. This valuable gas is in short supply the world over.

With the lowest boiling point of any gas (4.2 Kelvin or –269° Celsius), liquid helium is the coldest matter on Earth. This makes it ideal as a cryogenic agent for a number of cutting-edge medical applications. For instance, it is used to cool superconductive magnetic coils in magnetic resonance imaging (MRI).
