Claim 19:
20. A method of operating a multidimensional sample separation apparatus for separating a fluidic sample, the method comprising:
separating the fluidic sample by a first separation dimension comprising a first fluid drive unit for driving the fluidic sample and a first sample separation unit for separating the fluidic sample;
after separating the fluidic sample by the first separation dimension, supplying the separated fluidic sample to a second separation dimension for further separating the fluidic sample, wherein the second separation dimension comprises a second fluid drive unit for driving the separated fluidic sample and comprises a second sample separation unit and a third sample separation unit each of which being configured for further separating the separated fluidic sample; and
for further separating the fluidic sample by the second separation dimension, switching an outlet of the first separation dimension in fluid communication with at least one selected one of the second sample separation unit and the third sample separation unit so that an inlet pressure of the second sample separation unit and of the third sample separation unit is substantially the same at least at the point of time of switching.
