Nitrogen is an odorless and colorless gas which was discovered by Daniel Rutherford in 1772. Its name is derived from the Greek 'nitron' and 'genes' meaning nitre forming. By volume, it makes up 78% of the air and is naturally found in all living things.
It has a wide variety of applications in multiple industries. The chemical industry uses nitrogen for the production of fertilizers, explosives, nitric acids and for instance nylon. For these production methods, nitrogen has to first react with hydrogen to create ammonia.
In many high pressure testing applications for leak testing, gaseous nitrogen is utilized as a medium due to its low investment cost.
