What is Nitrogen?

Nitrogen is a colorless, odorless gas. Nitrogen is important to the chemical industry. It is used to make fertilizers, nitric acid, nylon, dyes and explosives. To make these products, nitrogen must first react with hydrogen to produce ammonia. This is done by the Haber process. 150 million tons of ammonia are produced in this way every year.

Nitrogen gas is also used to provide an unreactive atmosphere. It is used in this way to preserve foods, and in the electronics industry during the production of transistors and diodes. Large quantities of nitrogen are used in annealing stainless steel and other steel mill products.

Liquid nitrogen is often used as a refrigerant. It is used for storage for medical research and reproductive technology. It is also used to rapidly freeze foods, helping them to maintain moisture, color, flavor and texture.


Uses for Nitrogen

We offer compressed and liquid nitrogen in various grades specific to different applications, such as:

  • A coolant for concrete work
  • An assist gas for laser cutting
  • A pressurizing agent in pipelines
  • A cryogenic for preserving biological material
