Abstract: A continuous annular chromatography (CAC) device is disclosed including a stationary column head, a stationary eluate ring, a rotating body which is located between said column head and said collecting ring and which can rotate about a vertical axis and contains a chromatographic separating medium and a drive device. An extension can be coupled to a drive shaft of the drive device with a rapidly detachable connection.

Abstract: The invention relates to a CAC device comprising a stationary column head, a stationary eluate collecting ring, a rotating body which is located between said column head and said collecting ring and which can rotate about a vertical axis and contains a chromatographic separating medium; and a drive device. Said rotating body (1) is connected to a rotating platform (4) at its bottom end. This rotating platform (4) is slidingly, sealingly guided on the eluate collecting ring (5) and has an extension on the underside. The extension can be coupled to a drive shaft (2) of the drive device (8) with a rapidly detachable connection and the stationary column head the rotating body (1) with the rotating platform (4) and the attached eluate collecting ring (5) can be connected to form a CAC module and can be removed from the drive shaft (2) as a unit. The invention also relates to an inverse CAC method using the inventive device.

Abstract: The invention related to an annular chromatograph including a particle bed which rotates on a rotary plate (3), said plate having eluate drainage lines, with regard to a stationary base and a stationary feeder head (10) with continuous feeder lines. The annular chromatograph has a central column (2) provided on a rotary plate and extending upwards through the feeder head. A tightening device (16,17) for pressing the feeder head (10) on the cylinder sleeve (6) is arranged on said column.
