Abstract
An apparatus for countercurrent chromatography consisting of a coiled separation column which is rotated about the axis about which is it wound and the axis is also rotated about a main axis. The embodiments of the invention are based on the fact that the pattern of the centrifugal force field greatly changes with the ratio of the two radii of rotation and depending on the particular effect desired, the apparatus is configured to achieve the most effective force field to gain the effect. The separation column is a tube helix wound around a flexible core member which can be wound onto the coil holder in various orientations to further effect the desired results.
