Liquid-liquid chromatography in enantioseparations
Journal of Chromatography A, 2020Modern liquid-liquid chromatography mainly refers to the following two kinds of chromatographic apparatuses: countercurrent chromatography based on hydrodynamic equilibrium systems and centrifugal partition chromatography based on hydrostatic equilibrium systems.

This review covers the fundamental developments in the field of column liquid chromatography (LC) during the period of 1984-1985. In an attempt to conserve space, patents and theses have been excluded. Only articles published in English, French, German, and Russian with some exceptions have been included. As compared to the previous review (Anal. Chem.

For the separation of enantiomers or optical isomers by chromatography, a chiral setup is necessary. This is obtained by the temporary or permanent formation of diastereoisomers. For the latter approach the sample is derivatized with a chiral reagent, and the separation can then be achieved with a nonchiral chromatographic system; this is the 'indirect'

Liquid chromatography of troleandomycin
Journal of Chromatography A, 2001Until now no liquid chromatography (LC) method is described to determine the purity and content of troleandomycin and its related substances. A simple, robust, sensitive and selective isocratic liquid chromatographic method suitable for the determination of the antibiotic troleandomycin and its related substances is described. This method utilizes as a

Preparative liquid chromatography
Journal of Chromatography A, 2002The status of the theory and the main methods of implementation of preparative liquid chromatography are reviewed. On the theory front, the focus has recently shifted. The theory of non-linear, non-ideal chromatography has given rise to numerous models whose advantages, disadvantages and ranges of application are now well understood.

The Analyst, 1990
Triacylglycerols from rat adipose tissue were chromatographed by high-performance liquid chromatography (HPLC), with a gradient of propan-2-ol in acetonitrile as the mobile phase. Fractions of the material eluting from the column were collected and analysed by automated gas - liquid chromatography of the fatty acid methyl esters obtained after ...

Application of Ionic Liquids in Liquid Chromatography
Critical Reviews in Analytical Chemistry, 2007Interest in ionic liquids (ILs) for their potential application in analytical chemistry continues to grow. Their usefulness can be due to favourable physicochemical properties, like the lack of vapour pressure, good thermal and chemical stability as well as very good dissolution properties regarding both organic and inorganic compounds.

Micellar Liquid Chromatography
1988Micelles are notable for their ability to solubilize hydrophobic compounds in aqueous solution. Micellar solutions can help in improving analytical methodologies and in developing entirely new concepts in analytical chemistry; they have been studied especially as HPLC mobile phases.
