  • Melding Three Emerging Technologies: Pharmacogenomics, Digital Infrared and Argon Gas, to Eliminate Surgery, Chemotherapy and Radiation in Diagnosing and Treating Breast Cancer
    There are several reasons why the current breast cancer detection and treatment system in place in the United States is failing in its ability to serve all women in a way that is non-injurious and minimally invasive. First, radiation is cumulative and injurious, especially in younger breasts.
  • Beta testing an in-line monitor for moisture measurement in inert gas lines
    was described in an earlier issue of Designed to measure moisture levels in ultra-high-purity (UHP) nitrogen and argon gases, the monitor uses a piezoelectric quartz crystal microbalance (QCM) sensor. The quartz crystal is coated with a thin film of barium metal, with which moisture reacts irreversibly
  • MICRO: Ultraure Gases - McAndrew (Feb 2000)
    Methods Through atmospheric pressure ionization mass spectroscopy (APIMS), contamination levels in carrier gases such as nitrogen, argon, helium, and hydrogen can be detected to the single-parts-per-trillion level. This is sufficient to meet the most stringent requirements for atmospheric
  • Gas Tungsten Arc Welding
    The development of the GTAW process was accelerated early in 1940. Initially the process was called 'Heliarc', because Helium was used for the shielding gas. Later when argon was available the process was renamed tungsten inert gas or 'TIG'. Now, it is generally and preferably called gas tungsten
  • MICRO: Ultrapure Gas Delivery - Karwacki (February 2001)
    in excimer lasers is critical to the industry. While the actual amount of fluorine fueling a laser is typically <0.2% by volume, it is usually delivered to the laser at concentrations between 1 and 5% and then diluted at the point of use by rare gases such as krypton or argon in neon. Although gas costs
  • Tungsten Inert Gas (TIG) Welding Process
    of the completed weld in normal operation. Filler metal in the tungsten inert gas (TIG) welding process is typically used and argon inert gas or inert gas mixtures are used for shielding.
  • Ball Milling
    , the powder is annealed under a nitrogen (or argon) gas flow at temperatures of 1400oC for six hours.
  • The Hidden Costs of Compressed Air/Gas Leaks
    some time. In a parts manufacturing plant I found a huge argon leak. The feed line had a hairline split that was carrying the gas to a welder. Inert gases such as argon, helium, and nitrogen are non-toxic and do not burn or explode. However, they can cause injury or death at high concentrations
