    Applications

    1. Nitrogen Gas:
    Nitrogen gas has a variety of applications, including serving as an inert replacement for air where oxidation is undesirable;

    Nitrogen is commonly used during sample preparation procedures for chemical analysis;

    Nitrogen tanks are also replacing carbon dioxide as the main power source for paintball guns.

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

    2. Liquid nitrogen:

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