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.

Improved spiral tube assembly for high-speed counter-current chromatography [PDF]
Journal of Chromatography A, 2009 The original spiral tube support (STS) assembly is improved by changing the shape of the tubing, with 1-cm presses perpendicularly along the length. This modification interrupts the laminar flow of the mobile phase. The tubing in the four return grooves to the center of the rotor is flattened by a specially made pressing tool to increase the number of ...
