Abstract: An extraction cell (10) for a centrifugal partition chromatograph (20), which extraction cell (10) contains an extraction chamber (12) delimited by a cell wall (12c) and accommodates the liquid stationary phase (30á), and it has a liquid inlet opening (13b) and a liquid outlet opening (13k) serving to let in and out the liquid mobile phase (30m) to be made to flow through the extraction cell (10). The extraction cell (10) contains an extraction chamber (12) established as a tubular body, and a liquid inlet plug (16b) that includes a liquid inlet opening (13b) and a liquid outlet plug (16k) that includes a liquid outlet opening (13k), that can be attached to the extraction chamber (12) and an insert (14) through which liquids may pass is positioned in the extraction chamber (12) between the liquid inlet opening (13b) and the liquid outlet opening (13k).

Abstract: The object of the invention relates to an extraction cell for a centrifugal partition chromatograph, which extraction cell contains an extraction chamber delimited by a cell wall and accommodates the liquid stationary phase, and it has a liquid inlet opening and a liquid outlet opening serving to let in and out the liquid mobile phase to be made to flow through the extraction cell. The essence of the extraction cell is that it contains an extraction chamber established as a tubular body, and a liquid inlet plug that includes a liquid inlet opening and a liquid outlet plug that includes a liquid outlet opening, that can be attached to the extraction chamber. The object of the invention also relates to a centrifugal partition chromatograph containing such an extraction cell, and a method for producing such an extraction cell.

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.
