Download or read book Retention and Selectivity in Liquid Chromatography written by R.M. Smith and published by Elsevier. This book was released on 1995-01-13 with total page 479 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book brings together a number of studies which examine the ways in which the retention and selectivity of separations in high-performance liquid chromatography are dependent on the chemical structure of the analytes and the properties of the stationary and mobile phases. Although previous authors have described the optimisation of separations by alteration of the mobile phase, little emphasis has previously been reported of the influence of the structure and properties of the analyte.The initial chapters describe methods based on retention index group increments and log P increments for the prediction of the retention of analytes and the ways in which these factors are influenced by mobile phases and intramolecular interactions. The values of a wide range of group increments in different eluents are tabulated.Different scales of retention indices in liquid chromatography are described for the comparison of separations, the identification of analytes and the comparison of stationary phases. Applications of these methods in the pharmaceutical, toxicology, forensic, metabolism, environmental, food and other fields are reviewed. The effects of different mobile phases on the selectivity of the retention indices are reported. A compilation of sources of reported retention index values are given.Methods for the comparison of stationary phases based on the interactions of different analytes are covered, including lipophilic and polar indices, shape selectivity comparisons, their application to novel stationary phases, and chemometric methods for column comparisons.

This book was released on 2012-12-06 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern liquid column chromatography (LC) has developed rapidly since 1969 to become a standard method of separation. If the statisticians are to be believed, the recent growth of LC has been the most specta cular development in analytical chemistry and has not yet abated be cause its vast potential for application remains to be fully exploit ed. Significant factors contributing to this continued rise are the simplicity and low cost of the required basic equipment and the rela tive ease of acquiring and interpreting the data. Unfortunately, in LC, as so often in the field of analytical chemistry, the available commercial instruments are frequently far more complicated - and consequently far more expensive - than is nec essary for routine application. Therein also lies the risk of propa gating a "black box" philosophy that would be particularly detrimen tal to chromatography. Moreover, it appears to have been forgotten, as was done previously with gas chromatography, that inadequate sep aration by a column can be remedied only with great difficulty, if at all, by electronic means. Also, whether the capillary columns recent ly advocated with great enthusiasm for LC will fulfill the expecta tions of their proponents is highly questionable unless someone comes up with some new and revolutionary ideas.
