ABSTRACT
The cross-axis CPC produces a synchronous planetary motion of the column holder, which rotates about its horizontal axis and simultaneously revolves around the vertical axis of the apparatus at the same angular velocity. In the X−1.5L type of the apparatus, the column holder was mounted at an off-center position (X=10 cm and L=15 cm), which provides efficient mixing of the two-phase solvent systems and stable retention of the stationary phase in the coiled column.
