Abstract: A radioactive fluoride anion concentrating device capable of concentrating 18F− 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 ≦̸500 μm is cut out. The thickness of the sheet is desirably about 100 μm. The upper and lower sides of the flow cell (11) are fixed by fixing jigs (27) and (29).

Abstract: Ein lonensuppressor (1) beinhaltet lonenaustauschmembranen (41, 43) zwischen einem Paar von Elektroden (21, 23). In den Räumen zwischen den Elektroden und den lonenaustauschmembranen sind Regenerationsflüssigkeitskanäle (71, 73) vorgesehen und zwischen den Ionenaustauschmembranen ist ein Eluentenkanal (75) vorgesehen. Der lonenrücktausch im Eluenten auf der stromabwärts gelegenen Seite des Eluentenkanals wird supprimiert, wodurch die Detektionsempfindlichkeit für das zu messende Ion verbessert werden kann. So weist beispielsweise der Eluentenkanal eine gefaltete Struktur auf, wodurch die Strommenge auf der stromabwärts gelegenen Seite des Eluentenkanals erhöht wird und wodurch die Ansammlung von Ionen supprimiert wird und dementsprechend der lonenaustausch im Eluenten supprimiert werden kann.

Abstract: Disclosed herein is a suppressor using one ion-exchange tube which has an inner diameter close to that of a tube connected to a separation column and which is constituted by an ion-exchange membrane. The ion-exchange tube is folded or wound more than once in a plane into a sheet form to provide an ion-exchange tube sheet through which an eluate from a separation column flows. The ion-exchange tube sheet is accommodated in a container. The container provides a regenerant flow channel so that a regenerant is allowed to flow on both sides of the ion-exchange tube sheet.

Abstract: PROBLEM TO BE SOLVED: To perform multistage extraction in the flow channel in a microchip by a simple flow channel shape.
SOLUTION: Grooves different in cross-sectional area are respectively formed to the surfaces of two substrates and the groove forming surfaces of both substrates are laminated to form a flow channel having a protruded cross section, which comprises flow channel parts different in cross-sectional area, in the chip. A flow channel 14a is meandered in a continuous state while a flow channel 14b is branched into a plurality of flow channels and an extractable flow channel is formed at the place where the flow channel 14a and the flow channel 14b come into contact with each other. When two kinds of solvents different in properties are allowed to flow from an introducing port, multistage extraction can be performed at the place where the flow channel 14a and the flow channel 14b come into contact with each other. A two-phase flow becomes more stable by chemically treating the inner surfaces of the flow channels to make them hydrophilic or hydrophobic and an extraction effect is increased.
