The present invention relates to a process for the electro extraction of molecules from a moving fluid donor phase into an acceptor phase, comprising the steps of: providing an electrically conductive donor phase moving at a first flow velocity and in electrically conductive contact with a first electrode, providing an electrically conductive acceptor phase in direct contact and immiscible with the donor phase, in electrically conductive contact with a second electrode; and providing a supporting or confining phase guide pattern to keep a defined interface between donor phase and acceptor phase, and (d) applying an electrical field between the first and the second electrode.

Two-phase electroextraction from moving phases

The present invention relates to a droplet receiver, comprising a receptacle for receiving a droplet, a fluid conduit connected at a first end thereof to the droplet receptacle thereby providing a course within which the droplet received in the droplet receptacle moves, the conduit at its distal end in communication with a reservoir, and a fluid layer wetting the internal walls of the receptacle and conduit in such a way as permit reception of the droplet without loss of the received droplet due to wetting of the internal receptacle and conduit walls.

Method and device for receiving a droplet

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.
