FLUORIDE DRYING METHOD

摘要

The invention relates to methods and apparatus for drying [¹⁸F]fluoride which comprises (i) passing a [¹⁸F]fluoride solution comprising water, a solvent, [¹⁸F]fluoride, and a cationic counterion through a narrow bore vessel at elevated temperature such that the water and solvent are vaporised forming a vaporised component, and (ii) collecting the resulting vaporised component by condensing into a collection vessel.
