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.

In liquid-liquid chromatography the separation of the components of a mixture results from the distribution of the solutes between two immiscible liquids. One liquid is immobilized in the pores of a solid support and acts as the stationary phase. The other liquid, saturated with the stationary phase, is used as the mobile phase.

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 ...

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.

Countercurrent Chromatography: Liquid-Liquid Partition Chromatography without Solid Support
Science, 1970The liquid-liquid partition chromatographic system reported here involves a long helix of narrow-bore tubing. When the coiled tube is filled with one phase of a two-phase system and fed with the other phase, phase-interchange takes place in each turn of the coil, leaving a segment of the former phase as the stationary phase.

Classical liquid chromatography gave rise 15 years ago to new ideas about high-speed separations. Today, difficult separations can be made almost routinely by use of liquid chromatography instruments with automated controls and sensitive detectors. Sorptive effects are often best achieved with small, porous, "bonded phase" particles.

Fast Protein Liquid Chromatography
2010Fast protein liquid chromatography (FPLC) is a form of high-performance chromatography that takes advantage of high resolution made possible by small-diameter stationary phases. It was originally developed for proteins and features high loading capacity, biocompatible aqueous buffer systems, fast flow rates, and availability of stationary phases in ...
