摘要：
The invention generally relates to the preparation of 18F-!abeled radiopharmaceuticals. In particular, this invention relates to the advanced processes for an efficient eiution of [18F]fluoride trapped in a cartridge filled with quaternary ammonium polymer which comprises inert non-basic and non-nucleophilic counter anions. The said methods and polymer cartridges allow the rapid preparation of suitable [18F]fiuoride solution, which is also less basic to reduce the formation of byproducts, finally to increase radiochemical yield and purity of 18F-radiopharmaceuticals.
