Abstract
The object of the invention relates to an extraction cell (100) used in a centrifugal partition chromatograph, which has a cell wall (120) determining a closed extraction chamber (150), as well as an inlet (115) and an outlet (140) ensuring the fluid connection between the extraction chamber (150) and the space outside of the extraction cell (100) formed on essentially opposite parts of the cell wall (120). The extraction cell (100) according to the invention is constructed asymmetrically from the point of view of the reversibility of the direction of flow used when the centrifugal partition chromatograph is in operation.
