Ultra high purity, for analytical and process control applications

The atmosphere contains about 0.9 % of argon.

Argon is a neutral and colorless gas and does not however exist in nature other than in the air. It cannot sustain life, but it is highly used in certain industrial applications due to its high level of chemical inertness.
