PREPARATIVE CENTRIFUGAL CHROMATOGRAPHY DEVICE

摘要

An apparatus and method for preparative separation and collection of the components of a mixture by the use of a thin layer preparative centrifugal chromatography device in which a rotor mounted for rotation supports a thin layer of absorbent material used to separate the components of a mixture and a juxtaposed annular collection trough canted at an angle to the horizontal plane collects the separated and eluted components by means of a deflection surface canted toward the axis of rotation of the rotor at an angle of less than 90 DEG to the plane of the rotor. The chromatography device alternately consists of a series of rotors. The absorbent layer supported on the rotor is prepared by means of a chromatographic scraper device.
