摘要:A method for synthesizing an 18 F-labeled probe. The method includes a step of eluting an amount of 18 F with a first solvent which includes a predetermined amount of water and at least one organic solvent. In this step, the 18 F elutes as an 18 F solution. The method also includes a step of using the 18 F solution to perform 18 F-labeling in the presence of at least one labeling reagent and at least one phase transfer catalyst so as to generate the 18 F-labeled probe. In the method, there is no step of drying the 18 F starting from a time when the eluting step is performed and ending at a time when the 18 F-labeling step is performed.
