Fig. 6. (A) An illustration of the m-FFE gadget and its separation mechanisms. (i and iii) Free-flow zone electrophoresis is applied. (ii and iv) Free-flow isoelectric focusing application.62 (B) General principle of separation in free-flow electrophoresis: the analyte's electrophoretic mobilities are used to deflect the sample stream laterally in an electric field as it is constantly supplied into the separation chamber.63 (C) Feasibility to direct the components to particular chip outlets by hydrodynamically concentrating the sample streams between two buffer streams and altering the inlet flow ratio of the two sheath flow streams.64.
