Abstract
82Sr, produced by spallation reaction with medium-energy proton beams, was used to evaluate Bio-Rex 70 and Chelex-100 ion-exchange resins for use in a compact 82 Rb generator. Adsorption of 82Sr to the resin column, 82Rb elution yields, Sr breakthrough and 82Rb-Sr separation factors were determined for newly prepared columns and for long-term elution conditions. Separation factors of 107-108 were obtained with 2% NaCl elutions from Bio-Rex 70 resin columns while the separation factor was about 5 .times. 104 with the Chelex-100 resin column.
