In order to facilitate diffusive transfer of an entity such as a solute between immiscible fluids and subsequent separation of the fluids without mixing, method and apparatus are disclosed having first and second fluid flow paths (11, 12) carrying first and second immiscible fluids, the flow paths communicating with one another in an interface region (16) in which the fluids contact one another and a stable open interface is formed. Diffusive transfer takes place across the interface, and subsequently the fluids flow away from the interface without mixing. The width of the flow paths in the interface region measured normal to the interface lies between 10 and 500 micrometres.
Afin de faciliter le transfert par diffusion d'une substance, comme un soluté, entre des fluides non miscibles, et la séparation ultérieure des fluides sans mélange, l'invention propose une méthode et un appareil comportant un premier et un second circuits d'écoulement (11, 12), transportant le premier et le second fluides non miscibles; les circuits communiquent l'un avec l'autre dans une région formant interface (16), où les fluides sont en contact l'un avec l'autre, avec formation d'une interface ouverte stable. Le transfert par diffusion s'effectue via l'interface, les fluides s'écoulant et quittant l'interface sans se mélanger. La largeur du circuit dans la région de l'interface, mesurée perpendiculairement à l'interface se situe entre 10 et 500 micromètres.
