Nitrogen (N₂)

The inert gas used in a variety of applications including cutting, purging, cooling and freezing

Nitrogen is a non-flammable air gas that forms 78% of the earth's atmosphere.

Valued for its inert properties in its gaseous form, nitrogen displaces air and therefore, reduces or eliminates the oxidation of materials. It is also used as an assist gas for laser cutting. Given the extremely low temperatures of its liquid state, nitrogen is an ideal gas for cryogenic cooling and freezing.

Nitrogen can be used in virtually any industry to improve yields and optimise performance. It enables the safe storage and use of flammables and prevents the explosion of combustibles. In addition, nitrogen improves the quality and shelf-life of air-sensitive materials such as food, pharmaceuticals and electronic products.

Air Products offers liquid nitrogen and compressed nitrogen gas in a variety of purities and in various modes of supply around the world thanks to our network of storage and transfill facilities.

Safe Nitrogen Use

Nitrogen is odorless, colorless, tasteless, and non-irritating which means it has no warning properties and we can't detect its presence. It is non toxic and inert, but can act as a simple asphyxiant by displacing oxygen in air to levels below that required to support life.

Personnel, including rescue workers, should not enter areas where the oxygen concentration is below 19.5%, unless provided with a self-contained breathing apparatus or air-line respirator.
