Nitrogen is a colourless and odorless diatomic gas with the formula N2.

Product Introduction

Nitrogen is a colourless and odorless diatomic gas with the formula N2.
1.Many industrially important compounds, such as ammonia, nitric acid, organic nitrates (propellants and explosives), and cyanides, contain nitrogen.
2.Synthetically produced ammonia and nitrates are key industrial fertilisers, and fertiliser nitrates are key pollutants in the eutrophication of water systems.Apart from its use in fertilisers and energy-stores, nitrogen is a constituent of organic compounds as diverse as Kevlar used in high-strength fabric and cyanoacrylate used in superglue.
3.Nitrogen is a constituent of every major pharmacological drug class, including antibiotics. Many drugs are mimics or prodrugs of natural nitrogen-containing signal molecules: for example, the organic nitrates nitroglycerin and nitroprusside control blood pressure by metabolizing into nitric oxide.
4.Many notable nitrogen-containing drugs, such as the natural caffeine and morphine or the synthetic amphetamines, act on receptors of animal neurotransmitters.

Application

1.Nitrogen Gas:
Nitrogen tanks are also replacing carbon dioxide as the main power source for paintball guns.
In various analytical instrument applications: Carrier gas for gas chromatography, support gas for Electron Capture Detectors, Liquid Chromatography Mass Spectrometry, purge gas for Inductive Couple Plasma.

Material

(1)To fill light bulbs.
(2)In antibacterial atmosphere and instrument mixtures for biological applications .
(3)As a component in Controlled Atmosphere Packaging and Modified Atmosphere Packaging applications, calibration gas mixtures for environmental monitoring systems, laser gas mixtures.
(4)To inert many chemical reactions dry various products or materials.

Nitrogen can be used as a replacement, or in combination with, carbon dioxide to pressurize kegs of some beers, particularly stouts and British ales, due to the smaller bubbles it produces, which makes the dispensed beer smoother and headier.

2. Liquid nitrogen:
Like dry ice, the main use of liquid nitrogen is as a refrigerant.
