1. A method of transferring the mass of at least one solute between a liquid first phase and a liquid second phase that is immiscible with the first phase, the method comprising:

  • causing at least one droplet of said liquid first phase to move within a microfluidic device under drive from electric forces within a space filled with said liquid second phase,wherein said droplet is moved with said electric forces along a two-dimensional path between a point for injecting or creating said droplet in said microfluidic device, and an extraction and/or analysis zone, said path being determined in such a manner that said droplet sweeps through a fraction comprising at least 20% of said space filled with said liquid second phase.
