[Separation of isomeric compounds by high speed countercurrent chromatography].

Se pu = Chinese journal of chromatography, 2010
High speed countercurrent chromatography (HSCCC) was successfully used for the separation and preparation of isomeric compounds. The influence of various two-phase solvent systems on the resolution of the natural catechin isomers of (-) -epigallocatechin gallate (EGCG) and (-) -gallocatechin gallate (GCG) from green tea polyphenols and the synthetic ...

High-speed countercurrent chromatography for separation of americium from lanthanoids

Journal of Radioanalytical and Nuclear Chemistry, 2001
The separation of americium from lighter lanthanoids has been performedby high-speed countercurrent chromatograph (CCC) equipped with a small coiledcolumn. An extractant having higher affinity for americium, 5,8-diethyl-7-hydroxydodecan-6-oneoxime (LIX 63) was employed as a stationary phase.

High Speed Countercurrent Chromatography/Fourier Transform Infrared (HSCCC/FT-IR) Spectrometry

SPIE Proceedings, 1985
High Speed Countercurrent Chromatography/Fourier transform infrared (HSCCC/FT-IR) spectrometry is present-ed. High solute-to-solvent ratios can be obtained in separations performed using HSCCC. At these high solute concentrations it is possible to obtain spectra of solutes without solvent elimination, even in the presence of polar solvents, such as ...
