Nitrogen gas is an industrial gas produced by the fractional distillation of liquid air, or by mechanical means using gaseous air (pressurised reverse osmosis membrane or pressure swing adsorption). Nitrogen gas generators using membranes or pressure swing adsorption (PSA) are typically more cost and energy efficient than bulk-delivered ...

nitrogen gas is difficult to notice – it’s colourless, odourless and insoluble in water. its structure is two nitrogen atoms joined by a triple covalent bond.
Sep 28, 2017 · Nitrogen was discovered in 1772 by chemist and physician Daniel Rutherford, when he removed oxygen and carbon dioxide from air, demonstrating that the residual gas would not support living...
Antoine Lavoisier called the gas azote, meaning “no life,” because it did not support life. When it was discovered that the same element was also present in nitric acid and nitrate salts such as KNO 3 (nitre), it was named nitrogen.
Cavendish called the gas inflammable air from the metals in recognition of this most striking property. He also studied the gas we know call carbon dioxide, which had first been prepared by the Scottish chemist, Joseph Black in the 1750s.
