RE Resin

RE Resin is available in three particle sizes (100-150 um, 50-100 um, and 20-50 um), in the bottle sizes shown below and ready to use in slurry packed 2 mL columns (for gravity flow) or dry packed 2 mL cartridges (for use with vacuum system.)

RE Resin is an extraction chromatographic material which contains the same extractant as TRU Resin, octyl(phenyl)-N,N-diisobutylcarbamoyl-methylphosphine oxide (abbreviated as CMPO)in tributyl phosphate(TBP) coated on an inert methacrylic polymeric support. RE Resin contains a higher concentration of CMPO than TRU Resin to improve the retention of trivalent rare earths, actinides and Fe(III).

RE Resin is a favorable tool for the group separation of rare earth elements and has been used in conjunction with geological dating and radionuclide transport studies. Due to the high retention of yttrium on RE Resin it has also been applied to the purification of yttrium (Y90) used in cancer therapy. The DGA resins have replaced RE and TRU in many applications. However, RE and TRU still offer unique selectivity that may offer advantages over DGA in some applications.
