Countercurrent Chromatography (CCC) and Countercurrent Separation (CS)

Named after Craig's renowned countercurrent distribution (CCD), chromatographic liquid-liquid separation techniques are commonly referred to as countercurrent or partition chromatography (CCC, CPC). Owing to the fact that routine experimental setups such as HSCCC and CPC do not use true countercurrent flow of liquids, partition chromatography is the more generic term and actually describes the underlying principle of partitioning the analytes between two immiscible liquid phases. This also illustrates the particular power of CCC/CPC.

• As only solvents are involved and solid supports avoided, irreversible adsorption cannot occur, sample degradation is minimized, and a theoretical 100% sample recovery is achievable.

• The partition coefficient, K, is an important physicochemical constant of each molecular species, which can be used to target its analysis
