| pubmed-article:1113181 | pubmed:abstractText | An improved 82Sr-82Rb generator system, based on the complexing ion-exchange resin Chelex-100, has been developed. Columns of this material can be easily and rapidly milked, and the rubidium-strontium separation factor for a fresh generator under the experimental conditions studied was found to be greater than 10-7. Approximately 80% of the 82Rb present can be delivered in a 15-ml volume of aqueous 0.2 M NH4Cl solution. After more than 6 liters of eluant had passed through the generator, the rubidium-strontium separation factor was still observed to greater than 10-5 and no unusual strontium breakthrough behavior was seen in the system over nearly three 82Sr half-lives. | lld:pubmed |
