Autoclavable annular chromatograph

摘要

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. According to this method, the sample material is distributed over the entire periphery of the separating medium.
