This book introduces the reader to thermal field-flow fractionation and discusses its advantages over the fundamental problems associated with traditional column-based analytical techniques commonly used to characterize polymers and macromolecules. The authors discuss the theoretical background, equipment, experimental procedures as well as the recent advances and applications of thermal field-flow fractionation. Complete with several practical examples and troubleshooting guidelines, the book is written for beginners and experienced separation scientists alike and will enable its readers to optimize their experimental conditions for their specific separation needs and problems.

Field flow fractionation (FFF) is an emerging separation technique, which has been proven successful in the analysis of pharmaceuticals, biotechnology products, polymers, soils, and foods, among others. In this book, Martin Schimpf joins forces with Karin Caldwell and J. Calvin Giddings, two of the primary developers of this technique, to bring you the first comprehensive, one-stop reference on the technique.

Microthermal field-flow fractionation (micro-TFFF) is a new method of polymer and particle separation and analysis based on the effect of thermal diffusion (Ludwig-Soret effect); the relationships between molecular characteristics of the separated macromolecular and particulate species such as molar mass, particle size, chemical nature, and composition; and their distribution and separation characteristics such as retention. The book begins with a description of the theoretical principles of FFF, which apply equally to micro-TFFF, although the latter technique offers a number of important operational advantages, including superior cold-wall temperature regulation. Practical analytical aspects of experimental data analysis are discussed in detail. Typical methodological applications of micro-TFFF are given for polymers and particles of synthetic, natural, or biological origin. The book will be of interest to university and R&D scientists involved in the analysis and characterization of polymers, biopolymers, particles, and biological cells in polymer chemistry, colloid and interface science, microbiology, and the environmental sciences.

A comprehensive, practical approach to three powerful methods of polymer analysis and characterization This book serves as a complete compendium of three important methods widely used for the characterization of synthetic and natural polymers—light scattering, size exclusion chromatography (SEC), and asymmetric flow field flow fractionation (A4F). Featuring numerous up-to-date examples of experimental results obtained by light scattering, SEC, and A4F measurements, Light Scattering, Size Exclusion Chromatography and Asymmetric Flow Field Flow Fractionation takes an all-in-one approach to deliver a complete and thorough explanation of the principles, theories, and instrumentation needed to characterize polymers from the viewpoint of their molar mass distribution, size, branching, and aggregation. This comprehensive resource: Is the only book gathering light scattering, size exclusion chromatography, and asymmetric flow field flow fractionation into a single text Systematically compares results of size exclusion chromatography with results of asymmetric flow field flow fractionation, and how these two methods complement each other Provides in-depth guidelines for reproducible and correct determination of molar mass and molecular size of polymers using SEC or A4F coupled with a multi-angle light scattering detector Offers a detailed overview of the methodology, detection, and characterization of polymer branching Light Scattering, Size Exclusion Chromatography and Asymmetric Flow Field Flow Fractionation should be of great interest to all those engaged in the polymer analysis and characterization in industrial and university research, as well as in manufacturing quality control laboratories. Both beginners and experienced can confidently rely on this volume to confirm their own understanding or to help interpret their results.

The two companion volumes of "Advances in Polymer Science" - Volumes 150 and 151 - deal with recent progress in the characterization of polymers, mostly in solution but also at surfaces. The contributions comprise multidimensional chromatography for elucidation, the composition and the chain length distribution of copolymers, capillary electrophoresis of synthetic water-soluble polymers including polyelectrolytes, field flow fractionation techniques for quick and reliable separation and characterization of broad polymer samples and a novel application of thermal grating experiments for probing Brownian and thermal diffusion. Finally the rapid development of atomic forces techniques is reviewed with particular emphasis on the visualization of macromolecules and the patterning of surfaces.
