Argon

Argon is used for lighting. It may also be used to provide an inert atmosphere for certain projects when explosion or other forms of oxidation may pose a problem. Also used in “Geiger” counters, which measure radiation levels.

Nitrogen

Nitrogen has many industrial uses in the gaseous forms, but probably the most interesting is liquid nitrogen, which is extremely cold. Items that must be frozen to extremely low temperatures for preservation are frequently stored in liquid nitrogen. Documents, foods and chemicals are sometimes stored in nitrogen to keep them from oxidizing or reacting with air or water.
