METHOD FOR THE ELUTION OF 18F FLUORIDE TRAPPED ON AN ANION-EXCHANGE PHASE IN A FORM SUITABLE FOR EFFICIENT RADIOLABELING WITHOUT ANY EVAPORATION STEP

摘要

A method extracts out of an aqueous solution, concentrate and/or reformulate [18F] fluorides without any evaporation step. The eluting solution is a low water content, preferably 3% water, organic solution containing at least:a first compound (A) which is a tertiary alcohol-function bearing molecule,a second compound (B) which is a phase transfer agent suitable for radiolabeling and which is necessary to the anion exchange process.
