- W2017312803 abstract "A rapid and effective procedure for the preparation of carrier-free fluorine-18 is described. The F18 is produced by neutron irradiation of lithium carbonate and is separated by dissolving the material in acid and distilling off the hydrogen fluoride solution. The yield is better than 70 percent, radioactive impurities less than 2 ppm and the residual tritium content is less than 0.22 mc. On décrit un procédé rapide et efficate pour la préparation du fluor-18 sans porteur. On produit le F18 par l'irradiation neutronique du carbonate de lithium eton le sépare en faisant dissoudre le metériel dans de l'acide et en distillant la solution de fluorure d'hydrogéne. Le rendement est supérieur à 70 pour cent, les impuretés radioactives moins de 2 ppm et le contenu résiduel de tritium est inférieur à 0,22 mc.

Ein schnelles und wirksames Verfahren zur Herstellung von trägerfreiem F-18 wird beschrieben. Das F-18 wird durch Neutronenbestrahlung von Lithium Karbonat erzeugt und nachfolgend durch Lösung des Materials in Säure und Abdestillierung des Wasserstoff Fluors getrennt. Die Ausbeute ist besser als 70 Prozent, radioaktive Verunreinigungen weniger als 2 ppm und der restilche Gehalt an Tritium weniger als 0,22 mc." @default.
