Compressed Argon Gas

Cryo-Source creates and provides PurityPlus® Argon for use by diverse Portland companies.

Several properties helped Argon emerge as a winning choice for technical jobs, such as providing a thick atmosphere in which to single out neutrons in nuclear research, during the final years of the nineteenth century:

  • its inertness and molecular weight,
  • its comparative abundance in relation to other scarce gases, and
  • its commercial availability.

Unquestionably, the widest early application for dry, high-purity Argon was gassing the globes in incandescent light bulbs beginning in the early twentieth century. Later, with the invention and commercial advancement of gas metal arc (GMAW or MIG) and tungsten inert gas (TIG), welding in the 1940s necessitated a dense inert gas, primarily Argon-based. Allowing that none of these are true specialty-gas purity applications, the preference for them remains strong and they still represent a hefty piece of Argon’s sales volume.

Contemporary specialty gas applications for high-purity Argon include its use as a carrier or background gas in diverse analytical instrument applications, for example: in the identification and classification of trace and ultra-trace elements utilizing 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, especially those that use a high-efficiency Electron Capture Detector (ECD) or an Ultrasonic Detector (USD). It’s equally employed as a carrier gas to analyze hydrogen in helium with a TCD (Thermal Conductivity Detector) or USD. With the advancement of technology, Argon has been used most especially by the semi-conductor industry as a carrier/purge gas.
