What is it used for?
Applications & Reactions
How Nitrogen Gas (N₂) is used across industries, with the key chemistry explained simply.
Inerting & Blanketing
Displaces oxygen in storage tanks, pipelines, and process vessels to prevent fire, explosion, and oxidation of sensitive products during storage and transfer.
Modified Atmosphere Packaging (MAP)
Replaces air inside food packages to slow oxidation and microbial growth, extending shelf life for snacks, coffee, fresh produce, and processed meats.
Electronics & Semiconductor Manufacturing
Provides an ultra-dry, oxygen-free atmosphere for soldering, wave soldering, and reflow ovens. Prevents oxidation of solder joints and component leads.
Cryogenic Freezing & Cooling
Liquid nitrogen at −196°C enables rapid freezing of food products, biological samples, and medical specimens. Also used for cryogenic grinding and deflashing.
