Abstract:
1. A device for feeding samples to a separating device and for collecting sample fractions generated by means of the separating device, especially for high-performance liquid chromatography, the device comprising: (a) a first switch valve unit, which has at least eight ports and two switch positions, (b) a dosing device for feeding a sample to the first switch valve unit, which is connected to a suction port of the first switch valve unit, and (c) which is adapted to interact with a removal and discharge device for removing a sample from at least one sample-holding container and for discharging a fraction into one of several fraction-holding containers, the removal and discharge device being connected to a suction and discharge port of the first switch valve unit; (d) wherein a solution feed port of the first switch valve unit is adapted to be connected to a feed line for a first solution; (e) wherein a first separating device transfer port of the first switch valve unit is adapted to be connected to an input port of the separating device, and a second separating device transfer port of the first switch valve unit is adapted to be connected to an output port of the first separating device; (f) wherein a first port of a sample reservoir is connected to a first sample reservoir port of the first switch valve unit, and a second port of the sample reservoir is connected to a second sample reservoir port of the first switch valve unit; (g) wherein a waste port of the first switch valve unit can be connected to a container for waste of the first switch valve unit; and (h) wherein the ports of the first switch valve unit are assigned so that
