Application

Helium is a colourless and odourless rare gas that is much lighter than air. Application areas include leak detection, aeronautics, metallurgy, laser welding and technology, and meteorology (weather balloons). Helium is also used as a shielding gas, reactor cooling gas, carrier gas for gas chromatography, and cooling gas for production of optical fibres. It is also a filling gas for air bags and is a component of diving mixtures. Gas is easy to handle in a small, light pressure can, while the disposable container allows for aluminium recycling when finished.
