Four isoflavone components were purified from soybean extract by high-speed counter-current chromatography (HSCCC). Two types of multilayer coil separation columns were used: a small column made of standard 2.6-mm I.D. PTFE (polytetrafluoroethylene) tubing with a 260-ml capacity and a large column of convoluted PTFE tubing of 5.7-mm average I.D. with a

Efficient rare earth element (REE) separations are becoming increasingly important to technologies ranging from renewable energy and high-performance magnets to applied radioisotope separations. These separations are made challenging by the extremely similar chemical and physical characteristics of the individual elements, which almost always occupy ...

Laser-light-scattering detection for high-speed countercurrent chromatography
Journal of Chromatography A, 1991High-speed counter-current chromatography (HSCCC) is a powerful separation technique increasingly used in natural products chemistry. Evaporative laser light-scattering detection (ELSD) represents a universal detection method based on the following principle: the eluate [e.g.

Multilayer coil planet centrifuge for analytical highspeed counter-current chromatography
Journal of Chromatography A, 1989A compact portable model of a high-speed counter-current chromatograph enables efficient analytical separations of microgram sample quantities within 10 min. A series of preliminary experiments was conducted to study retention of the stationary phase of various two-phase solvent systems in short coils with different helical diameters. Under the optimal

[Separation of alkaloids in tea by high-speed counter-current chromatography].
Se pu = Chinese journal of chromatography, 2001Alkaloids extracted from the green tea were separated by high-speed counter-current chromatography. A series of experiments have been performed to investigate effects of different solvent system. A system of CHCl3-CH3OH-NaH2PO4(23 mmol/L) = (4:3:2) was selected, in which the upper phase was used as the stationary phase, and the lower phase as mobile ...
