Nitrogen
COMMERCIAL
GRADE – I (MAX. 2 PPM)
GRADE – II (MAX. 4 PPM)
Nitrogen (N2) constitutes 78.03% of the air, has a gaseous specific gravity of 0.967, and has a boiling point of -320.5°F (-195.8°C) at atmospheric pressure. It is colorless, odorless, and tasteless. Nitrogen is often used as an "inert" gas due to its non reactive nature with many materials. However, nitrogen can form certain compounds under the influence of chemicals, catalysts, or high temperature. Commercial nitrogen is produced by a variety of air separation processes, including cryogenic liquefaction and distillation, pressure swing adsorption (psa), and membrane separation.
