ABSTRACT
The very name of the technique, countercurrent chromatography (CCC), may be misleading for the nonspecialist in that there is no countercurrent motion in CCC. CCC is a chromatography technique in which both the stationary phase and the mobile phase are liquid. As detailed in previous pages of this book, the solvent biphasic liquid system is the heart of CCC. Concerning the '"hardware," two kinds of CCC chromatographs are marketed: the hydrodynamic machines and the hydrostatic machines.
