The asymmetric flow FFF (AF4) is realised in a separation channel where an separation force ist generated in form an asymmetric crossflow through a semipermeable membrane. The injected particles can be eluted in dependence of their physicochemical properties through a parabolic flow-profile in combination with the reduction of the crossflow. | The asymmetric flow FFF (AF4) is realised in a separation channel where an separation force ist generated in form of an asymmetric crossflow through a semipermeable membrane.
