Retention of the stationary phases of one organic-aqueous solvent system and three aqueous-aqueous polymer solvent systems was investigated on a cross-axis coil planet centrifuge. A graphic statistical treatment of all the data highlighted the prevailing effect of the inward-outward elution mode. A simplified model was proposed and studies on the paths and accelerations of cross-axis devices described in the previous paper provided explanations about the observed hydrodynamic behaviors.
