Abstract
A sample separation apparatus for separating a liquid sample includes a first separation unit for separating the sample, a first fluid drive for conducting the sample to be separated through the first separation unit, a second separation unit, arranged downstream of the first separation unit, for further separating the sample, a second fluid drive for at least partially conducting the sample through the second separation unit, and a fluidic valve having interfaces fluidically coupled to the first and second fluid drives and being switchable for performing the separation of the sample. The apparatus is configured for adjusting a pressure at a predefined position to a predefined value, wherein the predefined position is in a fluidic path between an outlet of the first separation unit and an inlet of the second separation unit or in fluid communication with this fluidic path.
