    • A method to extract out of water, concentrate and reformulate [18F] fluorides includes passing a dilute aqueous [18F] fluoride solution entering by an inlet (1) in a cavity (6) embodying an electrochemical cell with at least two electrodes (3, 4, 5), flowing in the cavity (6) and coming out of the cavity (6) by an outlet (2), an external voltage being applied to the electrodes. One electrode (4) is used as an extraction electrode, another one (3) is used for polarizing the solution, and configured so that at least the extraction electrode (4), either used as a cathode or as an anode, is in contact with and polarizes a large specific surface area conducting material (7), contained in the cavity (6). The extracted ions are released from the surface of the large specific surface area conducting material (7) by turning off the applied external voltage. During its passage in the cavity (6), the dilute aqueous [18F] fluoride solution entirely crosses and internally soaks the large specific surface area conducting material (7).
    • 提取出水,浓缩和重整[18 F]氟化物的方法包括使通过入口(1)进入的稀释的[18 F]氟化物水溶液在具有至少两个电极(3, 在腔(6)中流动并通过出口(2)从空腔(6)流出的外部电压施加到电极上。 使用一个电极(4)作为引出电极,另一个电极(3)用于使溶液极化,并且构造成使得至少用作阴极或阳极的引出电极(4)接触 使包含在空腔(6)中的大比表面积导电材料(7)极化。 通过关闭施加的外部电压,提取的离子从大比表面积导电材料(7)的表面释放。 在空腔(6)中通过期间,稀的氟化水溶液完全穿过并内部浸泡大比表面积导电材料(7)。
