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 princi

Column Handbook for Size Exclusion Chromatography is the first comprehensive reference to provide everything one needs to know about commercial analytical and preparative columns for size exclusion and gel filtration chromatography (SEC and GFC). SEC is now widely used as a quality assurance method in the polymer industry (both synthetic and biopolymers) to determine molecular weight and molecular weight distribution. The Handbook contains contributions from every column manufacturer around the world and from many experienced column users. It covers the technology, characterization, application, evaluation, maintenance, and quality control of analytical and preparative columns for SEC and GFC. Also included are columns for two closely related techniques, hydrodynamic chromatography and high osmotic pressure chromatography. Key Features * Evaluate and select columns with confidence for specific applications * Optimize separations and improve the ruggedness of analytical methods * Extend the service time of a column * Establish a quality-control program to ensure consistency in column performance * Avoid the expense of column damage or purchases that do not give the expected results

Although size exclusion chromatography (SEC) is perhaps the most popular and widely used technique for determining the molecular weight distribution of polymeric materials, there have been very few texts written on this topic. During the past decade, SEC has experienced a considerable amount of growth in regard to column and detector technology and new applications. With these advances, SEC can now be used for determining absolute molecular weight, polymer chain conformation and size, and branching, as well as polymer solution properties. This book introduces the reader to the fundamentals of SEC with emphasis on practical aspects of the technique, such as column and mobile selection, calibration, new detector capabilities and guidelines for performing SEC on most types of polymers, especially those of industrial importance. This book is intended for either those new to the field of SEC, or for those research workers who require a more comprehensive background.

Free radical species are generally short-lived due to their high reactivity and thus direct measurement and identification are often impossible. ESR is the only technique which has the potential for direct detection of radicals but in biological systems even these must be trapped by a spin-trapping agent. Thus most investigations involve recognition of indicators of the presence of radicals in vivo or ""FOOTPRINTS"" of radical-mediated damage. Techniques in Free Radical Research assembles and critically assesses the most relevant and reliable experimental approaches used towards t
