Available in PDF, EPUB and Kindle. Book excerpt: In view of linear free-energy relationships, LFER, chromatographic systems are “free-energy transducers,” translating differences in the structure of analytes into quantitative differences in physicochemical properties, like retention parameters. Hence, quantitative structure property (retention) relationships, QSP(R)R, bear valuable information on analytes and the separation systems involved. We illustrate here what can be achieved from the statistically valid and physically meaningful quantitative structure-retention relationships, QSRR. In particular, one can predict retention data, confirm identification, and optimize conditions of separation of given structurally defined analytes. Also, QSPR can shed light on the molecular mechanism of separation operating on specific stationary phases. Additionally, one can assess such properties of drug analytes of pharmacokinetic importance, like lipophilicity and acidity. Also, differences in interactions of xenobiotics with biomacromolecule components of chromatographic systems can conveniently be quantified. By means of QSRR, the chromatographic behavior of analytes in diverse separation systems can be related to their pharmacological properties.

Available in PDF, EPUB and Kindle. Book excerpt: Liquid chromatography has proved to be one of the most important tools for separations. Rapid development in biotechnology has increased the demand for chromatography in analytical, preparative and large scale applications. The understanding of the dynamics of chromatography is imperative for the scale-up. This book is a systematic treatment of the general rate models for various forms of liquid chromatography including adsorption, size exclusion, affinity, reversed phase, hydrophobic interaction, and radial flow chromatography. Thermodynamic and mass transfer effects in liquid chromatography are discussed. Applications of computer programs for the rate models are described and the procedures for the scale-up of preparative- and large-scale liquid chromatography using the general rate models are given.

This book was released on 1996 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this research, sulfoxides and sulfones were used as mobile phase additives and the effects of these additives on the retention behavior of some non-polar, polar, and chelate analytes were studied. The results of these experiments showed that dibutyl sulfoxide has a large effect on the reduction of the retention volumes of caffeine and Cr(acac)$\sb3.$ The effect of dibutyl sulfone on the retention behavior of analytes was similar to the effect of dibutyl sulfoxide. Additives such as dibutyl sulfoxide can be used to reduce the amounts of organic modifiers needed in some HPLC separations and to reduce problem of solvent storage and disposal. Loading capacity studies of dibutyl sulfoxide on the C18 stationary phase proved that dibutyl sulfoxide is dynamically modify the C18 stationary phase in HPLC. Also, these studies showed that there was a simple linear relationship between the amounts of mmoles of dibutyl sulfoxide actually taken up by the stationary phase and the logarithm of the corrected retention volumes for caffeine, theophylline, and the Cr(acac)$\sb3$ chelate.
