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 ...

Trends in countercurrent chromatography
TrAC Trends in Analytical Chemistry, 1986Abstract Since the early 1970s countercurrent chromatography has achieved a remarkable advance and is currently yielding rapid and efficient chromatographic separations that are comparable with those obtained with preparative high-performance liquid chromatography.

Numerical model for the investigation of countercurrent chromatography
Journal of Separation Science, 2011AbstractA numerical model is developed to describe the separation process of countercurrent chromatography (CCC) in this work. The theory of countercurrent extraction table (TCCET) is first proposed to calculate concentration distributions of chemical components in the CCC, which is essential for a numerical model to describe the dynamic equilibrium of

Development of High-Speed Countercurrent Chromatography
2021The preparative capability of the multilayer coil has been demonstrated in the separation of 1 g of the DNP amino acid mixture under the optimal operational conditions determined by the preliminary studies on short coils as described above. These centrifuge schemes are equipped with a novel flow-through mechanism which entirely eliminates the need for ...

Separation of Natural Products by Countercurrent Chromatography
2012Countercurrent Chromatography (CCC) provides the natural product chemist with a high-resolution separatory method, which is uniquely applicable to sensitive (unstable) compounds and which allows virtually quantitative recovery of the load sample. Different instruments use different means of retaining a stationary liquid phase.

Recent trends in multidimensional countercurrent chromatography
Journal of Separation ScienceCountercurrent chromatography (CCC) is a potent separation approach known for its remarkable efficiency and capacity in preparation. It's applied as a substitute or combined with different chromatographic techniques, resulting in its rebranding as multidimensional CCC (MDCCC).
