ABSTRACT:
Chromatographic column system, in particular a chromatographic column system of the expanded bed adsorption column type comprises a column connected to a fluid inlet and a fluid outlet and dimensioned to comprise an expandable filter bed between said fluid inlet and said fluid outlet. A top collector is adapted for collecting substance filtered by said filter bed and top collector actuator is provided for actuation of the top collector. A top stratum position detector is constructed and adapted to detect a top stratum of the filter bed when in expanded state; and a controller is provided communicatively coupled to said top stratum position detector and said top collector actuator, for moving the top collector as a function of a detected top stratum position. A clean and automated way is provided to optimize the collection of filtered substance.
