The realization of the electrochemical method for microfluidic radiosynthesis is described for concentrating aqueous no-carrier-added [(18)F]fluoride into an aprotic solvent in a disposable microfluidic cell. Flowing aqueous [(18)F]fluoride was introduced into a disposable microfluidic cell (16microL) under an electric potential (10V), followed by anhydrous MeCN. The trapped [(18)F]fluoride was released in MeCN containing Kryptofix 222-KHCO(3) (ca. 60microL) under heat and a reversed potential (-2.5V). An automated module provided the [(18)F]fluoride ready for subsequent microfluidic radiosynthesis in overall radiochemical yields of 60% within 6min.
