1. A fluid supply system for supplying a mobile phase in a sample separation device for separating a fluidic sample in a separation path, the fluid supply system comprising:
a proportioning unit configured to proportion multiple solvent components for composing the mobile phase and for providing a serial sequence of fluid packets each relating to a respective one of the solvent components;
a fluid drive unit configured to drive the mobile phase toward the separation path; and
a control unit configured to control the proportioning unit and the fluid drive unit so that an undefined portion of the mobile phase is removed from the mobile phase before delivering the mobile phase from the fluid drive unit to the separation path.
