82Rb Generating method and eluent

摘要

The present invention provides a low 82Sr breakthrough eluent and method of generating 82Rb from 82Sr from a 82Sr charged inorganic adsorbant column. Eluting is done with a pharmaceutically acceptable saline and buffer solution, which is preferably isotonic 82Sr breakthroughs of 10-8 are obtained at clinically useful elution rates greater than 10 ml per minute. Phosphate and carbonate buffers are preferred. Al2O3 and ZrO2 are preferred inorganic radiation damage resistant adsorbants.
