Abstract

A planar centrifugal chromatography device includes a chamber (2), and a rotor (3) arranged therein, driven by a motor (12) and serving as a separating element. The rotor has a supporting plate (15) with an adsorbing medium (4) provided thereon. A collecting device (5) is arranged near the outer edge of the rotor, but within the chamber. The characteristics of the invention include the collecting device (5) and the rotor (3) being mounted on a common shaft (10) and each individual point of a wall of the collecting device (5) being farther away from the axis of rotation (14) than the point of the adsorbing medium (4) which is farthest from the axis of rotation (14), and include the distances of individual points on the wall of the collecting device (5), measured from the axis of rotation (14), varying. At each point on the collecting device which is farther from the axis than two points which are adjacent to it, there is arranged an output opening (6) which is connected by a discharge channel (7) to a hollow part of the shaft (10) of the rotor (3), and wherein a stationary discharge element (8), for example a pump, is connected to the shaft (10).
