Chiral High-Speed Counter-Current Chromatography: Future Strategies for Chiral Selector Development. [PDF]
Curr Chromatogr, 2014 In conventional high-performance liquid chromatography, chiral separations are performed by chiral column with a chiral selector (CS) chemically boned to the solid support. In contrast, high-speed counter-current chromatography (HSCCC) performs chiral separations by dissolving CS in the liquid stationary phase.
