Abstract
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, with a first switch valve unit, which has at least eight ports and two switch positions. The device has a dosing device for feeding a sample to the switch valve unit, which is connected to a suction port of the first switch valve unit and which interacts with a removal and discharge device for the removal of a sample from at least one sample-holding container and for the discharge of each fraction into one of several fraction-holding containers, which is connected to a suction and discharge port of the first switch valve unit. The device uses a single switch valve unit configured in a new way to replace the function of two switch valve units, resulting in significantly simpler and cheaper construction.
