Progress of chiral countercurrent chromatography
Chinese Journal of Chromatography, 2016This article summarizes five characteristics of chiral countercurrent chromatography (CCC). The progress of chiral countercurrent chromatography is introduced. In the high speed countercurrent chromatography, the chiral selectors such as amino acid derivatives, cyclodextrin derivatives, chiral organic acid, polysaccharide and bovine serum albumin (BSA)

Resolution in Countercurrent Chromatography
Journal of Liquid Chromatography, 1985Abstract Using as an example the separation of DNP-glutamic acid and DNP-alanine in a nonplanetary countercurrent chromatograph, it was demonstrated that resolution, Rs, of a solute pair can be satisfactorily predicted from knowledge of the column efficiency, N, the fraction of column volume occupied by stationary phase, SF, and the partition ...

multifraction separation in countercurrent chromatography (MCSGP)
Biotechnology and Bioengineering, 2013ABSTRACTThe multicolumn countercurrent solvent gradient purification (MCSGP) process is a continuous countercurrent multicolumn chromatography process capable of performing three fraction separations while applying a linear gradient of some modifier.

Comparison of Countercurrent Chromatography with Flash Chromatography
Journal of Liquid Chromatography & Related Technologies, 1998Abstract Studies of the separation of benzyl, phenylethyl and phenylpropyl alcohols by flash chromatography (FC) on 1.0 × 30 or 1.9 × 15 cm silica gel columns are compared with separation by countercurrent chromatography (CCC) on a 1.68 mm × 24 m, 56 mL, PTFE multilayer coil.

Chiral Separations by Countercurrent Chromatography
2019Chiral separations by countercurrent chromatography are mainly divided into two types: homogeneous chiral selector addition and interfacial chiral ligand exchange. In this chapter, we describe two methods for the enantioseparation of phenylsuccinic acid and α-hydroxy acids by high-speed countercurrent chromatography using hydroxypropyl-β-cyclodextrin ...
