title: New angle rotor coil planet centrifuge for counter-current chromatography. II. Design of the apparatus and studies on phase retention and partition capability.
abstract: A new angle rotor coil planet centrifuge (psi = 25 degrees), which produces a Type J-L synchronous planetary motion, has been constructed to examine its capability in terms of stationary phase retention and solute partitioning. Studies on phase distribution diagrams obtained from various two-phase solvent systems indicated that the present system can be adapted to a wide variety of solvent systems by adjusting the centrifugal conditions. Excellent partition capability of the apparatus was successfully demonstrated in separations of dinitrophenyl amino acid samples with chloroform-acetic acid-0.1 N hydrochloric acid (2:2:1).
