摘要： A system and method for continuously separating different isotopes of a particular element, such as Uranium, Zirconium, or Hydrogen, in an electrolytic medium. The ions of the isotopes to be separated are moved in the electrolytic medium using electric field. As the lighter ions will move faster than the heavier ions, the separation will happen and the lighter ions will be ahead of the heavier ions by a separation distance. To improve the separation, other forces (either proportional to the mass or not) are generated on the ions in directions that add additional separation factors. These forces could be centrifugal, electromagnetic, resistive dragging, mechanical (flow), etc. The invented separation process and device is simple and less expensive than other comparable devices, providing outstanding separation at low cost, and could be built using the already available materials and technologies that exist in any country in the world.

摘要： Both a method and apparatus for separating zirconium isotopes by balanced ion migration in a counterflowing electrolyte are disclosed herein. In the method of the invention, zirconium chloride is dissolved in a solution of HCl, and a voltage of between 2 and 50 volts is applied across the electrolyte to create a flow of zirconium ions toward the cathode, and a counterflow of chlorine ions toward the anode which is balanced such that the lighter weight isotopes of zirconium migrate toward the cathode while the heavier weight zirconium isotopes stay in the vicinity of the anode. The apparatus of the invention includes a polarizing assembly formed from a bundle of small diameter glass tubes aligned between the anode and the cathode. The internal shape of the tubes impedes kinetic agitation movement of the zirconium ions in all directions except in the direction between the anode and the cathode, thereby expediting the separation process. Glass frits are used to partition off the electrolyte in the region of both the anode and the cathode so that the isotopes which eventually accumulate in these regions may be drawn off with a minimum of fluid agitation.

摘要： A method for separating electrically charged species contained in a solution by an isotachophoresis method applied in an electrophoresis device, the isotachophoresis method being coupled to isotopic measurement using a mass spectrometer. The method notably comprises a step of stopping the voltage applied to the terminal of the electrophoresis capillary and transient application of a counter-pressure making it possible to utilize the length of the capillary several times and extend the separation distance artificially.

摘要： A method for isotope measurement of charged species contained in a solution to be analyzed, particularly charged species having an isobaric interference, has the following consecutive steps: a) in the capillary of a capillary electrophoresis device, the solution to be analyzed is inserted contiguously between a terminating electrolyte and a leading electrolyte that, respectively, are placed after the inlet and before the outlet of the capillary and contain ions of the same charge but with mobility inferior and superior to those of said species; b) separating the species by using the capillary electrophoresis device according to the isotachophoresis mode; then c) in the continuity of the preceding step, performing an isotope measurement of the species detected in the form of a substantially constant amplitude signal by using an inductively coupled plasma mass spectrometer (ICPMS) connected by direct coupling with the capillary electrophoresis device.

摘要： A flowcell 2 is constituted of insulating substrates 2a and 2b. The two substrates 2a and 2b have been directly bonded to each other by a bonding method for attaining tenacious bonding, for example, anodic bonding or hydrofluoric acid bonding. A channel 6 has been formed at the interface between the substrates 2a and 2b. Part of the substrate 2a which faces the channel 6 has a carbon electrode 4a formed thereon by sintering a pasty carbon material, the electrode 4a extending along the channel 6. On the other hand, the substrate 2b has a groove 6a serving as the channel 6, and has an electrode 4b made of a metal film formed on a bottom surface of the groove 6a.
