Micro free-flow electrophoresis (μFFE) is a continuous separation technique in which analytes are streamed through a perpendicularly applied electric field in a planar separation channel. Analyte streams are deflected laterally based on their electrophoretic mobilities as they flow through the separation channel. A number of μFFE separation modes have been demonstrated, including free zone.

Free-flow electrophoresis (FFE) is a technique that performs an electrophoretic separation on a continuous stream of analyte as it flows through a planar flow channel. The electric field is applied perpendicularly to the flow to deflect analytes laterally according to their mobility as they flow through the separation channel Free flow isotachophoresis was applied to the purification of immunoglobulins from human serum. Disadvantages of this technique are the time‐consuming development of an optimized separation system and the empirical search for suitable spacers

Free flow electrophoresis using different mobility of ions in an electric field is a promising alternative to established separation processes. Very good results in separating metal ions could be obtained and even improved to a purity of up to 100 % by using complexing agents.
