| 摘要 |
The invention relates to a method for transferring magnetically marked particles (36) from a first medium flow to a second medium flow, in which the magnetically marked particles (36) are introduced, together with the first medium flow and the second medium flow, into a throughflow duct (12) and flow in laminar fashion, forming an interface (22), through the throughflow duct (12), wherein the magnetically marked particles (36) are deflected, by means of a magnetic field gradient, in a first direction (z) toward a duct floor (14) of the throughflow duct (12). The magnetically marked particles (36) deflected in the first direction move on in the flow direction, close to the duct floor (14), and are deflected, by means of at least one barrier (32) arranged on the duct floor (14), in a second direction (x) perpendicular to the flow direction and perpendicular to the interface (22) to the point that they pass from the first medium flow into the second medium flow. The invention also relates to a device for carrying out the method. |
