Compressed Argon Gas

Sidney Lee Medical & Scientific Gases originates and supplies PurityPlus® Argon for those companies in Atlanta, GA that need it.

Certain qualities helped Argon emerge as a perfect choice for technical jobs, such as providing a heavier atmosphere in which to isolate 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 practicability.

Unquestionably, 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. In due course, with the invention and commercial development of gas metal arc (GMAW or MIG) and tungsten inert gas (TIG), welding in the 1940s necessitated a dense inert gas, normally Argon-based. Even though none of these are genuine specialty-gas purity applications, their popularity is stronger than ever and they still represent a huge portion of Argon’s sales volume.

Modern 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 discovery and classification 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 is applied as well in many kinds of Gas Chromatography, especially those involving a high-efficiency Electron Capture Detector (ECD) or an Ultrasonic Detector (USD). It’s also used as a carrier gas when analyzing hydrogen in helium with a TCD (Thermal Conductivity Detector) or USD. As things have progressed, Argon has found its greatest use in the semi-conductor industry as a carrier/purge gas.
