Product Description

High Purity 99.9999% Nitrogen N2 Gas Used In The Manufacture of Stainless Steel




Nitrogen is a colorless and odorless gas with symbol N and atomic number 7.


Nitrogen is an essential building block of amino and nucleic acids, essential to life on Earth.


Elemental nitrogen in the atmosphere cannot be used directly by either plants or animals, and must be converted to a reduced state to be useful for higher plants and animals. Precipitation often contains substantial quantities of ammonium and nitrate, thought to result from nitrogen fixation by lightning and other atmospheric electric phenomena. However, because ammonium is preferentially retained by the forest canopy relative to atmospheric nitrate, most fixed nitrogen reaches the soil surface under trees as nitrate. Soil nitrate is preferentially assimilated by tree roots relative to soil ammonium, however this is not the case for all species.


Specific bacteria possess nitrogenase enzymes that can fix atmospheric nitrogen into a form that is chemically useful to higher organisms. This process requires a large amount of energy and anoxic conditions. Such bacteria may live freely in soil but normally exist in a symbiotic relationship in the root nodules of leguminous plants and fertilizer trees. Nitrogen-fixing bacteria are also symbiotic with a number of unrelated plant species such as alders spp., lichens, Casuarina, Myrica, liverworts, and Gunnera.


As part of the symbiotic relationship, the plant converts the 'fixed' ammonium ion to nitrogen oxides and amino acids to form proteins and other molecules. In return for the 'fixed' nitrogen, the plant secretes sugars to the symbiotic bacteria. Legumes maintain an anaerobic environment for their nitrogen-fixing bacteria.


Plants are able to assimilate nitrogen directly in the form of nitrates that may be present in soil from natural mineral deposits, artificial fertilizers, animal waste, or organic decay. Nitrates absorbed in this fashion are converted to nitrites by the enzyme nitrate reductase, and then converted to ammonia by another enzyme called nitrite reductase.
