Improved cross-axis synchronous flow-through coil planet centrifuge for performing counter-current chromatography. I. Design of the apparatus and analysis of acceleration.
A novel design of the cross-axis synchronous flow-through coil planet centrifuge is introduced. The apparatus holds a pair of large coil holders symmetrically, one on each side of the rotary frame, at a lateral position 12.5 cm from the center of the holder shaft held 10 cm from the centrifuge axis. Mathematical analysis of acceleration generated by the planetary motion of the apparatus revealed a unique centrifugal force field which promises high retention of the stationary phase in the multilayer coil to perform efficient preparative-scale counter-current chromatography.
