Abstract
A sample separation device includes a separation path and a control unit. The separation path is between a fluid drive and a sample separation unit, and is configured to inject a fluidic sample in an injector path into a mobile phase in the separation path driven by the fluid drive to the sample separation unit for chromatographically separating the fluidic sample. The control unit is configured to control blocking the injector path or at least a partial path thereof, generating an overpressure in the blocked injector path or the partial path thereof by a pressure source, and subsequently fluidically coupling the injector path or the partial path thereof to a region of lower pressure than the overpressure to generate an expansion stroke for releasing unwanted components from the injector path.
