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.

Field-flow fractionation has become a very effective method for the separation and analytical characterization of substances of macromolecular and particulate character-making this method probably the most important discovery in the analytical separation field since World War II. The first, complete, up-to-date reference on this notable separation method, Field-Flow Fractionation includes comprehensive explanations of general and theoretical principles . . . presents detailed descriptions of experimental techniques and instrumentation ... and discusses advantages over competitive processes. In addition, this resource demonstrates various applications for characterizing synthetic polymers ... analyzing biopolymers and particles in environmental samples ... and determining sizes of biological cells, viruses, and subcellular particles. Substantiating main conclusions of theories, experiments, and applications with graphs and drawings, and including numerous tables and photographs, this one-source reference is invaluable reading for analytical, industrial, physical, and polymer chemists; chrom­ atographers; biochemists; biotechnologists; biophysicists; and all others interested in the study and characterization of macromolecules or particles of various origins.

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.

This Springer Laboratory volume introduces the reader to advanced techniques for the separation and fractionation of polyolefins. It includes detailed information on experimental protocols and procedures, addressing the experimental background of different polyolefin fractionation techniques in great detail. The book summarizes important applications in all major fractionation methods with emphasis on multidimensional analytical approaches. It comprises the most powerful modern techniques, such as high temperature size exclusion chromatography (HT-SEC) for molar mass analysis, temperature rising elution fractionation (TREF) and crystallization analysis fractionation (CRYSTAF) for the analysis of chemical composition and branching, high temperature two-dimensional liquid chromatography (HT-2D-LC), solvent and temperature gradient interaction chromatography (SGIC and TGIC) and crystallization elution fractionation (CEF). Beginners as well as experienced chromatographers will benefit from this concise introduction to a great variety in instrumentation, separation procedures and applications. With detailed descriptions of experimental approaches for the analysis of complex polyolefins, the readers are offered a toolbox to solve simple as well as sophisticated separation tasks. The book starts with an introduction into the molecular complexity of polyolefins - the most widely used synthetic polymers with rapidly growing production capacities. It systematically discusses crystallization based fractionation techniques including TREF, CRYSTAF and CEF and column chromatographic techniques for molar mass, chemical composition and microstructure, as well as the combination of different fractionations in multidimensional experimental setups. This book also includes basic information on the application of high-temperature field-flow fractionation.
