Atmospheric Gases

Atmospheric gases are the gases normally found in the air around us. They include air, argon, carbon dioxide, helium, nitrogen and oxygen.

Of these gases argon, oxygen and nitrogen are produced primarily by the separation of air into its constituent components. This is normally achieved by reducing the temperature of the air until each component liquefies and can be taken away.

Of the two other gases in this section carbon dioxide is produced as a by-product of several chemical processing procedures.
