Recent Trends in Counter-Current Chromatography

TrAC - Trends in Analytical Chemistry, 2012
Abstract Counter-current chromatography (CCC) has been widely used as a preparative chromatography technique since Ito first developed it in the late 1960s. This technique uses a support-free liquid stationary phase, which is retained by gravity or centrifugal force. The analytes can access the whole stationary phase, leading to effective separation.

Separation of Antibiotics by Counter-Current Chromatography

Journal of Chromatography A, 1998
This paper reviews recent applications of counter-current chromatography (CCC) to the separation of antibiotics. It also covers the recent development of CCC instruments and the optimization of the two-phase solvent system. The CCC technique offers a high resolving power when the proper solvent system is carefully selected and becomes a powerful tool ...
