Nitrogen is commonly used as carrier as in gas chromatography.
Nitrogen is used to fill tires to lower wear and limit the risks of blow-outs.
Liquid nitrogen is used in cold traps to improve the efficiency of vacuum pumps by condensing or solidifying residual gases in the vacuum.
Liquid nitrogen is used to freeze a wide variety of delicate food, such as hamburgers, strawberries, shrimps etc.
Liquid nitrogen is used in the nuclear industry, for scientific research.

Process
Nitrogen is produced in large quantities at air separation plants which liquefy and subsequently distill air into nitrogen, oxygen, and usually argon. If very high purity nitrogen is required the nitrogen produced may need to go through a secondary purification process. The lower range of nitrogen purities can also be produced with membrane techniques, and medium to high purities with pressure swing adsorption (PSA) techniques.
