Abstract:
A LEAK-PROOF ELECTRIC CELL IS FORMED BY ARRANGING A SEPARATOR LAYER CONSISTING OF A GRANULAR SWELLABLE ANION EXCHANGE COMPOUND OR A MIXTURE OF SUCH ANION AND CATION EXCHANGE COMPOUNDS BETWEEN THE NEGATIVE ELECTRODE AND THE DEPOLARIZER OF THE CELL. THE CELL IS MADE BY APPLYING A SUSPENSION OF THE ANION EXCHANGE COMPOUND IN A SOLUTION OF A BINDING AGENT TO THE INNER WALL OF A CUP-SHAPED METAL ELECTRODE, PREFERABLY A ZINC CUP ELECTRODE AND THEN REMOVING THE SOLVENT SO AS TO LEAVE A UNIFORM FILM ON THE INNER WALL OF THE ELECTRODE CUP.
Abstract:
The invention relates to a method of performing a plurality of synthesis processes of preparing a radiopharmaceutical in series, which method comprises carrying out a first synthesis run comprising the steps of: a) providing water containing 18F; b) trapping the 18F from the water provided in step a) on an anion exchange material (18); c) eluting the trapped 18F from the anion exchange material (18) to a reaction vessel (58) of first radiopharmaceutical synthesis cassette (50'); d) preparing a radiopharmaceutical incorporating the eluted 18F using the first radiopharmaceutical synthesis cassette (50'); wherein steps a)-d) are repeated in at least one subsequent run using another radiopharmaceutical synthesis cassette (50"; 50"'); and wherein the method comprises a reconditioning step of said anion exchange material (18) between two consecutive runs Other aspects of the invention relate to a device for performing this method, and a cassette for use in the device.
Abstract:
Die Erfindung betrifft ein adsorptives Filtermedium (d.h. eine Filtereinheit bzw. Filterstruktur), welche sich zur Aufreinigung von Gasen und/oder Gasgemischen, vorzugsweise Luft, sowie zur Entfernung von chemischen und/oder biologischen Giften und/oder Schadstoffen aus Gasen und/oder Gasgemischen, vorzugsweise Luft, eignet, sowie dessen Verwendung.
