Abstract

L'invention se rapporte à un procédé permettant de faire fonctionner une pompe comportant des électrodes et conçue pour pomper un liquide. Ledit procédé consiste à inverser périodiquement la polarité de la tension appliquée aux électrodes de la pompe tout en maintenant un flux net de liquide dans une direction souhaitée (Fig. 1). L'invention se rapporte également à un appareil conçu pour pomper du liquide à l'aide d'une pompe à électrodes et comportant un canal de dimensions capillaires, une pompe comportant au moins deux électrodes insérées à l'intérieur du canal ; un organe de commande conçu pour commander les tensions appliquées aux électrodes de sorte que les pompes fonctionnent sous l'effet d'un diagramme à répétition de cycles de polarité, et de sorte qu'au cours de la période du diagramme répété on obtient soit (a) qu'un premier rapport d'une aire (A1) intégrée en tension, associée à une première polarité, à une aire (A2) intégrée en tension, associée à l'autre polarité, soit (b) qu'un second rapport d'une charge (q1) transportée par le courant associé à une première polarité à une charge (q2) transportée par le courant associé à l'autre polarité, soit compris entre 1:1/2 environ et 1/2:1 environ. L'invention se rapporte également à des appareils et procédés de mise en oeuvre d'une électrophorèse.
