Winona Specialty Gas Equipment Spotlight: Gas Purifiers


It won’t come as a surprise to most, but our stock in trade at Mississippi Welders Supply Co., Inc. is providing specialty gases for commercial, industrial, medical, scientific, and agricultural use. But customers are well aware they also can depend on us for the gear necessary to move, store, check on, and work with those gases safely. One such category of equipment they certainly value is our line of gas purifiers.

The Winona semiconductor industry particularly comes to us for point-of-use gas purifiers that eliminate impurities down to part-per-trillion (pptV) levels. This sort of purity is imperative for making not only semiconductors but also [[various display, LED, and solar products.

To be specific, we deliver …

  • high-pressure gas purifiers, these versions built for use in all types of laboratory and industrial research where oil or water must be kept out of a gas to enhance its effectiveness and avert equipment shutdown.
  • gas purifiers that, while much like our high-pressure models, are engineered to deal with higher capacities at a lower working pressure.
Both of these purifiers must used along with specially constructed replaceable cartridges that contain one of a number of adsorbents. As determined by the cartridge/adsorbent ordered, these purifiers can remove more than oil and water from industrial process gases; they’re also capable of removing water from inert gases and saturated hydrocarbons, removing various particulates, and removing water from unsaturated hydrocarbons – acetylene, for instance.
  • a series of gas purifiers specifically made to remove up to 1% of oxygen from a hydrogen stream down to a level under 1 ppm. They achieve this by catalytic action. If the catalytic materials aren’t fouled (especially by sulfur and halogens), they’ll perform pretty much permanently and not need regeneration.
