Abstract
A fluid processing apparatus includes a first fluid separation apparatus including a first fluid pump, configured for driving a first mobile phase, and a first separation unit configured for separating a fluidic sample when within the first mobile phase. A sampling unit includes a modulation buffering unit and a modulation drive, wherein the modulation drive is configured for introducing fluid into the modulation buffering unit. A switching unit is configured, in a first switching state, for introducing fluid into the modulation buffering unit from downstream of the first separation unit, and, in a second switching state, for introducing fluid buffered in the modulation buffering unit in a first flow path between the first fluid pump and the first separation unit.
