Compressed Argon Gas

Cee Kay Supply, Inc. creates and provides PurityPlus® Argon for use by various St. Louis businesses.

Certain characteristics ensured that Argon would become a winning candidate for technical uses, such as providing nuclear physicists with the dense atmosphere necessary to segregate neutrons, at the conclusion of the nineteenth century:

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

Easily, the most notable early use for dry, high-purity Argon was gassing the globes in incandescent light bulbs during the first years of the twentieth century. Later, with the invention and commercial introduction of gas metal arc (GMAW or MIG) and tungsten inert gas (TIG), welding in the 1940s had to have a dense inert gas, typically Argon-based. Even though none of these are bona fide specialty-gas purity uses, the preference for them shows no sign of disappearing and they still represent a large piece of Argon’s sales volume.

Nowadays, the most prevalent 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 identification and study of trace and ultra-trace elements by means of Inductive Coupled Plasma Techniques, in Graphite Furnace Atomic Absorption, and in Fourier Transform Infrared spectroscopy. Argon also finds application in many types of Gas Chromatography, especially those that use 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. As things have progressed, Argon has been used most especially by the semi-conductor industry as a carrier/purge gas.
