Enantioseparations in Counter-Current Chromatography and Centrifugal Partition Chromatography

Journal of Chromatography A, 2001
Examples of chiral separations in counter-current chromatography (CCC) and centrifugal partition chromatography (CPC) are not numerous, due to the difficulty of finding chiral selectors highly selective in the liquid phase as well as a combination of solvents that does not destroy the selectivity and retains the capacity to elute chiral isomers of ...

Deep Eutectic Solvents in Countercurrent and Centrifugal Partition Chromatography

Journal of Chromatography A, 2016
Deep eutectic solvents (DESs) were evaluated as solvents in centrifugal partition chromatography, a liquid-liquid chromatography separation technology. To this end, the partition coefficients of ten natural compounds of different hydrophobicity were determined in non-aqueous biphasic systems containing DES.

Centrifugal Partition Chromatography. II. Selectivity Efficiency

open access: yesJournal of Liquid Chromatography, 1988
Abstract Centrifugal Partition Chromatography (CPC) is a technique that uses two immiscible liquids. One liquid is used as a stationary phase, the second one as the mobile phase. Using the liquid systems methanol-hexane and octanol-water, the selectivity and efficiency of CPC apparatus were tested.

Centrifugal Partition Chromatography. I. General Features

open access: yesJournal of Liquid Chromatography, 1988
Abstract Centrifugal Partition Chromatography (CPC) is a variant of countercurrent chromatography (CCC). As in CCC, two immiscible liquids are used. The first liquid is the stationary phase, the second is the mobile phase. The liquid stationary phase is held in channels engraved in several polychlorotrifluoroethylene (PCTFE) plates.

Measurement of Partition Coefficient Using Centrifugal Partition Chromatography

open access: yes, 1995
Measurement of partition coefficients in various solvent systems has been developed using flow-through centrifugal partition chromatography (CPC). The present paper details the experimental design, and shows that this method is able to measure compounds in a log P range of ca. -3.2 to 3.2 in a precise, accurate and rapid way.

Centrifugal Partition Chromatography: Application to Natural Products in 1994–2009

open access: yesJournal of Liquid Chromatography and Related Technologies, 2010
Centrifugal partition chromatography (CPC) is a type of counter current separation technique and was first invented by Sanki Eng. Ltd. in Kyoto. Since the year of 1982, CPC has been used to isolate or fractionate bioactive materials and has shown its ...
