Compressed Argon Gas American Welding & Gas, Inc. originates and distributes PurityPlus® Argon for various businesses that can make use of it in Indianapolis. Certain attributes made Argon a perfect candidate for technical jobs, such as providing a thick atmosphere in which to segregate neutrons in nuclear research, at the conclusion of the nineteenth century:its inertness and molecular weight,its perceived abundance when compared to other rare gases, andits commercial workability.Easily, the most common early use for dry, high-purity Argon was gassing the globes in incandescent light bulbs during the first years of the twentieth century. In due course, with the invention and commercial introduction of gas metal arc (GMAW or MIG) and tungsten inert gas (TIG), welding in the 1940s needed a dense inert gas, primarily Argon-based. While it’s true that none of these are true specialty-gas purity uses, the call for them hasn’t lessened and they still compose a significant piece of Argon’s sales volume. Current 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 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 finds further application in many kinds of Gas Chromatography, especially those that involve a high-efficiency Electron Capture Detector (ECD) or an Ultrasonic Detector (USD). It’s frequently used also as a carrier gas for analyzing 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.
