18F-Labeled fluorotrimethylsilane was prepared by nucleophilic substitution of chlorotrimethylsilane with reactor produced [18F]fluoride. Hydrolysis of fluorotrimethylsilane by aqueous tetraethylammonium hydroxide followed by removal of water with a mechanical pump gave a powerful source of no carrier added nucleophilic 18F. Reaction

[18F]Fluorotrimethylsilane was prepared in 80% decay corrected yield by reaction of no-carrier added tetramethyl-ammonium fluoride (hydroxide as bulk anion) with chlorotrimethylsilane in 65% aqueous acetonitrile. The 18F gas was collected in a cold-trap at -130 degrees C and found to

The conventional procedure for separation of fluoride as trimethylfluorosilane in Conway diffusion cells involves the use of grease for sealing the cell and also for closing the hole in the lid drilled for introduction of hexamethyldisiloxane. We have developed a

A selective dynamic method for the determination of fluoride in pharmaceuticals based on the integration of pervaporation and potentiometric detection in a laboratory-made module is proposed. The analyte was continuously converted into volatile trimetylfluorosilane by reaction with hexamethyldisilazane, injected into
