Compressed Argon Gas

Mississippi Welders Supply Co., Inc. produces and provides PurityPlus® Argon for commercial use in Winona.

Several properties helped Argon emerge as a perfect choice for technical uses, such as providing a dense atmosphere in which to single out neutrons in nuclear research, in the late 1800s:

  • its inertness and molecular weight,
  • its perceived abundance when compared to other scarce gases, and
  • its commercial practicability.

Easily, the most significant early use for dry, high-purity Argon was gassing the globes in incandescent light bulbs during the first years of the twentieth century. By and by, with the invention and commercial emergence of gas metal arc (GMAW or MIG) and tungsten inert gas (TIG), welding in the 1940s needed a dense inert gas, normally Argon-based. While none of these are honest-to-goodness specialty-gas purity uses, the desire for them is stronger than ever and they still make up a notable segment of Argon’s sales volume.

Present-day specialty gas applications for high-purity Argon include its use as a carrier or background gas in a range of analytical instrument applications, for example: in the ferreting out and study of trace and ultra-trace elements employing Inductive Coupled Plasma Techniques, in Graphite Furnace Atomic Absorption, and in Fourier Transform Infrared spectroscopy. Argon also finds application in many aspects of Gas Chromatography, notably those that use a high-efficiency Electron Capture Detector (ECD) or an Ultrasonic Detector (USD). It also works as a carrier gas when analyzing hydrogen in helium with a TCD (Thermal Conductivity Detector) or USD. Over the years, Argon has found its greatest use in the semi-conductor industry as a carrier/purge gas.
