Argon (Ar)

An inert gas with unique properties used in a variety of industrial and analytical applications

Argon is a non-flammable gas that forms 0.9 percent of the earth's atmosphere.

Most commonly used in the metal industry for metal production, processing and fabrication, it can be used as a pure gas for certain shielding, blanketing, annealing and hot isostatic pressing (HIPing) applications. It can also be used as part of a mixture with other gases, in particular carbon dioxide, oxygen, nitrogen, hydrogen or helium, depending on the process and material.

Its inert properties make argon popular in other industries such as the glass industry for double glazing, the food industry for removing oxygen from wine barrels, and analytical laboratories who use it as a carrier gas in gas chromatography (GC) and in ICP-MS equipment.

Air Products offers compressed argon gas and liquid argon in a variety of purities and in various modes of supply around the world thanks to our network of storage and transfill facilities.

Industrial gases (such as nitrogen, hydrogen, and argon) for furnace atmospheres are characterized by their very high purity (>99.995%). Typical impurity levels are much less than 10 parts per million by volume (ppmv) oxygen and less than 3 ppmv moisture (
