Applications
Nitrogen is widely used as an inert blanketing gas in chemical processing, food packaging, and metal heat treatment. In the electronics industry, ultra-high purity nitrogen is used in semiconductor fabrication for purging, blanketing, and as a carrier gas. Other applications include cryogenic cooling, laser cutting, and as a component in calibration gas mixtures.
