MULTI-ELEMENT ISOTOPIC MEASUREMENT BY DIRECT COUPLING OF A MULTI-CYCLE ISOTACHOPHORESIS TECHNIQUE AND A MASS SPECTROMETRY TECHNIQUE

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 ap...

Summary: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.
