Specialty Gas Equipment Spotlight: Gas Purifiers


At PurityPlus®, specialty gases for commercial, industrial, medical, scientific, and agricultural use are our stock in trade. But customers know they also can depend on us and our more than 150 partners at 600 locations nationwide for the equipment necessary to transport, store, monitor, and use those gases safely. One such type of equipment they appreciate is our line of gas purifiers.

The semiconductor industry especially looks to us for point-of-use gas purifiers that remove impurities down to part-per-trillion (pptV) levels. This kind of purity is essential for manufacturing not only semiconductors but also various display, LED, and solar products.

Specifically, we offer …

  • high-pressure gas purifiers, these models designed for use in all sorts of laboratory and industrial applications where oil or water must be kept out of a gas in order to improve its utility and avoid equipment shutdown.
  • gas purifiers that, while similar to our high-pressure models, are built to handle higher capacities at a lower working pressure.
  • Both of the above must be used in conjunction with specially designed replaceable cartridges that are filled with one of a number of adsorbents. Depending on the cartridge/adsorbent ordered, these purifiers can remove more than just 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 designed to remove up to 1% of oxygen from a hydrogen stream down to a level of less than 1 ppm. They accomplish this by catalytic action. As long as the catalytic materials aren’t contaminated (especially by sulfur and halogens), they’ll function indefinitely and not require regeneration.
