Compressed Argon Gas

Fresno Oxygen & Welding Supplies/Barnes Welding Supply originates and supplies PurityPlus® Argon for use by various Fresno businesses.

A few significant attributes made Argon an excellent choice for technical applications, such as providing nuclear researchers with the thick atmosphere required to separate neutrons, at the conclusion of the nineteenth century:

  • its inertness and molecular weight,
  • its abundance in comparison to other rare gases, and
  • its commercial availability.

To be sure, the most significant 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 emergence of gas metal arc (GMAW or MIG) and tungsten inert gas (TIG), welding in the 1940s had to have a dense inert gas, primarily Argon-based. While it’s true that none of these are honest-to-goodness specialty-gas purity applications, the preference for them is stronger than ever and they still compose a hefty portion 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 number of analytical instrument applications, for example: in the detection 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 finds further application in many kinds of Gas Chromatography, notably those involving a high-efficiency Electron Capture Detector (ECD) or an Ultrasonic Detector (USD). It’s also used as a carrier gas for 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.
