Separation method based on a combination of electrophoresis and interactions of the analytes with additives (e.g. surfactants), which form a dispersed phase moving at a different speed (velocity). In order to achieve separation, either the analytes or this secondary phase should be charged.
Notes: - This is not totally compatible with the definition of chromatography.
- Surfactants must be at concentrations above their critical micelle concentration for being able to form a dispersed phase – otherwise they will just act as ion-pair reagents.
