Introduction:
Argon (Ar) is present in atmospheric air in very small quantity (about 0.9%). It is colorless, odorless gas and highly inert (non-reactive) like Nitrogen.
Argon is a colorless, odorless, tasteless and nontoxic gas. Argon, along with helium, neon, krypton, xenon and radon is also known as a “rare” gas. Argon forms no known chemical compounds. The gas is 1.38 times heavier than air and is slightly soluble in water. Argon is present in the atmosphere at a concentration of 0.93%. Argon is recovered from air in an Air Separation Unit (ASU) where it is drawn off as a cryogenic liquid at about -303°F. Argon can then be distributed as a cryogenic liquid or as a gas in cylinders.
Common applications include:
◆ Inerting (shielding to avoid Oxidation of metals/pigments).
◆ Limits the proliferation of bacteria.
◆ Food preservation
◆ Tig and Mig welding
Supply options:
◆ Cylinders/dewars/clusters
◆ Bulk deliveries/storage systems.
