Compressed Argon Gas

A-OX Welding Supply originates and sells PurityPlus® Argon for those enterprises in Sioux Falls that have need of it.

Certain qualities ensured that Argon would become a top choice for technical jobs, such as providing a thick atmosphere in which to separate neutrons in nuclear research, toward the end of the nineteenth century:

  • its inertness and molecular weight,
  • its relative abundance compared to other uncommon gases, and
  • its commercial workability.

Without doubt, the most common early application for dry, high-purity Argon was gassing the globes in incandescent light bulbs as the twentieth century was getting underway. Later, with the invention and commercial development of gas metal arc (GMAW or MIG) and tungsten inert gas (TIG), welding in the 1940s required a dense inert gas, primarily Argon-based. Even though none of these are true specialty-gas purity uses, their popularity shows no sign of disappearing and they still make up a huge portion of Argon’s sales volume.

Current specialty gas applications for high-purity Argon include its use as a carrier or background gas in various analytical instrument applications, for example: in the exposure and analysis of trace and ultra-trace elements using Inductive Coupled Plasma Techniques, in Graphite Furnace Atomic Absorption, and in Fourier Transform Infrared spectroscopy. Argon additionally finds application in many aspects of Gas Chromatography, notably those that make use of a high-efficiency Electron Capture Detector (ECD) or an Ultrasonic Detector (USD). It’s frequently used also as a carrier gas when analyzing hydrogen in helium with a TCD (Thermal Conductivity Detector) or USD. Over the years, Argon has been used most extensively by the semi-conductor industry as a carrier/purge gas.
