The present invention relates to a method to extract out of an aqueous solution, concentrate and/or reformulate [18F] fluorides without any evaporation step, characterised in that 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.
本发明涉及一种无需任何蒸发步骤即可从
水溶液中提取、浓缩和/或重配[18F]
氟化物的方法,其特征在于洗脱溶液是一种含
水量较低,优选<3%
水的有机溶液,至少含有以下物质:
- 第一种化合物 (A),它是一种含叔醇功能的分子、
- 第二种化合物(B),它是一种适用于放射性标记的相转移剂,是阴离子交换过程所必需的。
