Application

Nitrogen is a colourless, odourless, and asphyxiating gas that is slightly lighter than air. Nitrogen is used as a carrier gas in gas chromatography, an inert gas in chemical and pharmaceutical industries, and a zero gas for analytical applications, such as in the automotive industries. Nitrogen is also used as a component of gas mixtures for CO2 lasers. Gas is easy to handle in a small, light pressure can, while the disposable container allows for aluminium recycling when finished.
