Abstract
The invention relates to a device and a process for nucleophilic fluorination of a substance, especially for synthesis of anF-labeled substance for examination using a positron emission tomograph. The device comprises an anion exchange device () for extraction of [F]fluoride ions by means of adsorption from a target fluid, whereby the anion exchange device () can be charged via a supply device () with the target fluid; and a measurement device () with a measurement chamber () for measuring initial radioactivity of the [F]fluoride ions, the anion exchange device () being arranged at least partially in the measurement chamber () of the measurement device ().
