RADIOCATIVE FLUORINE ANION CONCENTRATING DEVICE AND METHOD

摘要

A radioactive fluorine anion concentrating device capable of concentrating <SUP>18</SUP>F<SUP>- </SUP>ions speedily and efficiently. A flow cell (11) is composed of a metal plate electrode (21), an insulating sheet (23) and a carbon plate electrode (25) located so that the sides of electrodes may be opposed to each other with the insulating sheet (23) inserted between them. An example of the plate metal plate electrode (21) is obtained by forming a film of metallic material on an insulation plate, and an example of the insulating sheet (23) is a PDMS from which a groove being a channel (26) having a thickness of = 500µm is cut out. The thickness of the sheet is desirably about 100µm. The upper and lower sides of the flow cell (11) are fixed by fixing jigs (27) and (29).
