Abstract: A sample separation apparatus includes a fluid drive arrangement having a first fluid drive unit and a second fluid drive unit for driving a mobile phase along a flow path to a sample separation unit, a sample accommodation volume configured to accommodate the fluidic sample and to be selectively fluidically coupleable with the flow path or fluidically decoupleable from the flow path, and a control unit configured to control respective operations of the fluid drive units, and to control a fluidically decoupling of the second fluid drive unit from the flow path in a decoupled operation mode of the sample separation apparatus. The control unit is further configured to control, in the decoupled operation mode, the decoupled second fluid drive unit for fluidically coupling to the sample accommodation volume, and intaking sample into the sample accommodation volume.
