There is a large and increasing variety of polymers currently in use both for domestic and industrial applications. The properties of polymers are deter mined not only by their chemical type, but also by their molecular mass and molecular mass distributions. However, while the chemical type of polymers can be determined relatively easily, the average molecular masses and molecular mass distributions are more difficult to measure. The molecular mass averages of a polymer are measured by specialized and complex techniques such as light scattering (for weight average) and osmometry (for number average). Thus, complete characterization of the molecular mass distribution of a polymer by such means requires separating the sample into many fractions which can then be examined individually. Since size exclusion chromatography was introduced as a rapid and straightforward technique for the characterization of polymer molecular mass distributions, there have been tremendous increases in development and applications, and it was felt appropriate to bring together into a single volume the information required by scientists from many disciplines who wish to use the technique. This book should be useful to existing users, those who are new to the technique, and those who may be familiar with the basic technique and now wish to extend their capabilities to more complex applications (or to consider the potential of a number of related techniques). The book will also be of general interest to the experienced liquid chromatographer.

Size-exclusion chromatography (SEC) is used for the characterization and/or separation of macromolecules. Size-based sampling of column pore volume provides information in terms of the molar mass averages and distributions of disperse polymers. The history of the development, the basic theory of column separations, calibration, and detection strategies for obtaining absolute molar mass information are described, as are modern multidetector techniques and the incorporation of SEC into two-dimensional liquid chromatographic arrangements.

The latest edition of the authoritative reference to HPLC High-performance liquid chromatography (HPLC) is today the leading technique for chemical analysis and related applications, with an ability to separate, analyze, and/or purify virtually any sample. Snyder and Kirkland's Introduction to Modern Liquid Chromatography has long represented the premier reference to HPLC. This Third Edition, with John Dolan as added coauthor, addresses important improvements in columns and equipment, as well as major advances in our understanding of HPLC separation, our ability to solve problems that were troublesome in the past, and the application of HPLC for new kinds of samples. This carefully considered Third Edition maintains the strengths of the previous edition while significantly modifying its organization in light of recent research and experience. The text begins by introducing the reader to HPLC, its use in relation to other modern separation techniques, and its history, then leads into such specific topics as: The basis of HPLC separation and the general effects of different experimental conditions Equipment and detection The column—the "heart" of the HPLC system Reversed-phase separation, normal-phase chromatography, gradient elution, two-dimensional separation, and other techniques Computer simulation, qualitative and quantitative analysis, and method validation and quality control The separation of large molecules, including both biological and synthetic polymers Chiral separations, preparative separations, and sample preparation Systematic development of HPLC separations—new to this edition Troubleshooting tricks, techniques, and case studies for both equipment and chromatograms Designed to fulfill the needs of the full range of HPLC users, from novices to experts, Introduction to Modern Liquid Chromatography, Third Edition offers the most up-to-date, comprehensive, and accessible survey of HPLC methods and applications available.

For four decades, size-exclusion chromatography has played a prominent role in characterizing polymers, by determining the polymer's molar mass averages, often not absolutely but relative to some calibration standard. Not satisfied, scientists now want to determine the absolute molar mass averages and distribution and to characterize their long-chain and short-chain branching, tacticity, copolymer and base-pair sequences, and other matters. Oh yes, and they want all this as a continuous function of the molar mass of the analyte. Fortunately, the technique is endowed with a number of detection methods, and the 18 papers here explain the role of those various detection methods and the synergistic effect of combining them in different configurations to obtain desired results.

The rapid development of new packings for aqueous size-exclusion chromatography has revolutionized this field. High resolution non-adsorptive columns now make possible the efficient separation of proteins and the rapid and precise determination of the molecular weight distribution of synthetic polymers. This technology is also being applied to the separation of small ions, the characterization of associating systems, and the measurement of branching. At the same time, fundamental studies are elucidating the mechanisms of the various chromatographicprocesses.These developments in principles and applications are assembled for the first time in this book. Fundamental issues are dealt with: the roles of pore structure and macromolecular dimensions, hydrophobic and electrostatic effects, and the determination and control of column efficiency. High-performance packings based on derivatized silica are reviewed in detail. Special techniques are thoroughly described, including SEC/LALLS, inverse exclusion chromatography, and frontal zone chromatography. Attention is focussed on special applications of size-exclusion methods, such as the characterization of micelles, separations of inorganic ions, and Hummel-Dreyer and related methods for equilibrium systems. Protein chromatography is dealt with in both dedicated sections and throughout the book as a whole.This is a particularly comprehensive and authoritative work - all the contributions review broad topics of general significance and the authors are of high repute. The material will be of special value for the characterization of synthetic water-soluble polymers, especially polyelectrolytes. Biochemists will find fundamental and practical guidance on protein separations. Researchers confronted with solutes that exhibit complex chromatographic behavior, such as humic acids, aggregating proteins, and micelles should find the contents of this volume illuminating.
