Countercurrent Chromatography: Liquid-Liquid Partition Chromatography without Solid Support [PDF]
Science, 1970 The 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.

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 ...

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.

Science, 1982
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.

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.

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 ...

Liquid Chromatography—The Background
1972Liquid chromatography has an impressive history, stretching back into the 19th century, which has been well documented elsewhere(1). As an indispensable technique for the separation and analysis of organic substances it has made enormous strides in the past decade or so. Prior to 1958 column chromatography was conducted with comparatively large samples
