Basic factors that determine the effect of planetary centrifuges used in countercurrent
chromatography are considered. An expression for the tangential projection of the centrifugal inertial force is
obtained for rotating coiled column motion which is a sum of two rotations in the same direction around two
parallel axes at different angular velocities. It is shown that the proposed physical model can describe both
the chromatographic separation of components and existence of stationary phase retention due to the force
field in rotating coiled columns.
