Nitrogen is a colorless, odorless, non-flammable, and inert gas that makes up about 78% of the Earth’s atmosphere. In its gaseous form, nitrogen is widely used across various industries as a blanketing, purging, and inerting medium due to its ability to displace oxygen and prevent oxidation or combustion. In liquid form (LIN), nitrogen is utilized for refrigeration, cryogenic preservation, and specialized cooling applications.
