Abstract
An apparatus for countercurrent chromatography consisting of a horizontal helical column array which is rotated about its own axis and simultaneously is rotated around a stationary central horizontal pipe at the same angular velocity to prevent twisting of its inlet and outlet flow tubes, which extend through the stationary central horizontal pipe. The column array is parallel to the stationary central pipe. The planetary motion allows both gravity and centrifugal force acting at respective times to provide high efficiency analytical and preparative scale separations on a broad spectrum of two-phase systems.
