Application

Hydrogen is a colourless, odourless, and flammable gas that is much lighter than air. It is used as a carrier gas in gas chromatography and as a fuel gas for flame ionization detectors (FID). Hydrogen is also a shielding gas and cooling gas in metallurgy and glass industries. Gas is easy to handle in a small, light pressure can, while the disposable container allows for aluminium recycling when finished.
