Centrifugal Partition Chromatography (CPC), also known as Counter Current Chromatography (CCC), is a silica-free liquid-liquid chromatographic technique for preparative and industrial scale purifications. Two non-miscible liquid phases are used, one as the mobile phase, or the eluent, and the other as the stationary phase maintained by a centrifugal field. The affinity of the solute for each phase, measured by their partition coefficient, gives their order of elution. 
 
CPC/CCC can be used for a wide range of applications such as synthetic compound purification, natural extract fractionation, natural compound purification, and proteins separations.
