DOWEX Resins for Separation of the Noble Gases

Noble Gases Helium - He Neon - Ne Argon - Ar Krypton - Kr Xenon - Xe Radon - Rn The Noble Gases are characterized by closed shell electronic structures and thus do not form ionic species under normal conditions. Ion exchange resins and adsorbents are not commonly applied to Noble Gas separations.

Applications

Since gases are often used in a compressed form, they are often contaminated with compressor lubricants. DOWEX™ OPTIPORE™ polymeric adsorbents have been shown to work well to remove these compressor lubricants from compressed gas streams.

DOWEX OPTIPORE polymeric adsorbents can be used to remove contaminants such as volatile organic compounds.
