The present invention relates to a process for the extraction of analyte compounds from a sample comprising one or more analytes in a donor phase into an acceptor phase, comprising the steps of: a) providing an electrically conductive donor phase comprising the compounds in a first electrically conductive solvent or solvent blend, and an electrode arranged in electrically conductive contact with the donor phase, b) providing an electrically conductive acceptor phase in electrically conductive contact with a second electrode; and c) providing an insulator phase in fluid communication with at least one of the donor phase and the acceptor phase, wherein the insulator phase is immiscible with the donor phase and/or the acceptor phase, and d) (d) applying an electrical field between the first and the second electrode.
