ABSTRACT:
A method and apparatus for transporting electrically charged particles suspended in a fluid, such as ions or the like, through said fluid, in a transport direction by means of a traveling electrostatic surface wave. The apparatus includes an array of transport electrodes to which a source of AC multi-phase potential is applied to create a stable and controllable particle transport system in which the charged particles have a compound motion comprising a generally cyclical movement and drift movement through the fluid, in the transport direction. The locus of charged particle movement is maintained above the surface of the electrode array.
