Strontium-82, 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 Rb-82 generator. Adsorption of Sr-82 to the resin column, Rb-82 elution yields, Sr breakthrough, and 82Rb-Sr separation factors were determined for newly prepared columns and for longterm elution conditions. Separation factors of 10(7) to 10(8) were obtained with 2% NaCl elutions from Bio-Rex 70 resin columns while the separation factors was about 5 X 10(4) with the Chelex-100 resin column.
通过中能质子束散裂反应产生的锶-82，被用于评估Bio-Rex 70和Chelex-100离子交换树脂在紧凑型铷-82发生器中的应用。测定了新制备的柱以及长期洗脱条件下锶-82在树脂柱上的吸附、铷-82的洗脱产率、锶的穿透以及82Rb-Sr分离因子。从Bio-Rex 70树脂柱用2%氯化钠洗脱时获得了10⁷至10⁸的分离因子，而Chelex-100树脂柱的分离因子约为5×10⁴。
