Helium industrial gas

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, which is why many applications incorporate recovery and recycling systems. 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 and physics applications. For instance, it is used to cool superconductive magnetic coils in magnetic resonance imaging (MRI) and nuclear magnetic resonance (NMR) medical equipment. In fact, helium is indispensible across a wide range of industries. For example, it is used to pressurise rocket fuel; create inert atmospheres for welding, heat treatment and epitaxial crystal growth; purge semiconductor atmospheres; calibrate analytical instruments; inflate airplane tyres and airbags; test for leaks; inflate large balloons for meteorological studies; and fill electronic tubes in neon signs.
