09887 IUPAC Gold Book - countercurrent chromatography 10.1351/goldbook.09887 09887 current initialism: CCC 1 Partition chromatography which uses two immiscible liquid phases and no solid support. One liquid acts as the stationary phase and the other as the mobile phase. The method employs a variety of systems using either gravity or centrifugal force to retain the stationary phase in the column. The method allows continuous elution of the mobile phase and on-line monitoring of the effluent. PAC, 2017, 90, 181.
