Book Description
Fractionation of polymers via solubility has been a well known method in polymer characterization for a long time. The original object of analytical fractionations, the determination of the molecular weight distribution, is nowadays achieved more efficiently and conveniently by chromatographic methods. However, fractionation procedures, which were developed in great diversity, remain up~to-date and essential for obtaining preparative fractions with narrow distributions. Such fractions are wanted increasingly for the investigation of true structure-property relationships which are mostly influ~ enced by distributions of molecular weight or other parameters such as branching or chemical composition. Literature on the field of polymer fractionation is extensive and several reviews exist. However, there is a lack of systematically methodical instruc tions for carrying-out of diverse fractionation procedures. This volume repre sents an attempt to reduce this deficiency and is focussed on practical aspects of fractionation procedures. This laboratory manual is intended for polymer chemists, physicists, and technicians, for students of polymer science, and skilled laboratory assistants, all of whom are not dealing directly with fractionation but are in need of fractions to carry out further investigations.

Book Description
Polymer Fractionation focuses on the processes, reactions, and transformations involved in polymer fractionation, including chromatography, titration, and sedimentation. The selection first offers information on theoretical considerations and fractional precipitation. Topics include polydispersity of high polymers, phase relations for polydisperse systems, fractionation theory and efficiency, and fractionation by solvent evaporation. The manuscript then takes a look at fractional solution, chromatographic fractionation, and gel permeation chromatography. The book elaborates on thermal diffusion and turbidimetric titration, as well as methods of fractionation, studies of the variables, outline of the method and range of application, and elaboration of the method. The text then ponders on sedimentation, isothermal diffusion, and summative fractionation. Discussions focus on mathematical interpretation of summative data, experimental methods for the determination of diffusion constants, and methods for the determination of the diffusion coefficient distribution. The selection is a valuable source of information for readers interested in polymer fractionation.

Book Description
This book is divided into chapters covering instrumentation, sedimentation velocity runs, density gradient runs, application examples and future developments. In particular, the detailed application chapter demonstrates the versatility and power of AUC by means of many interesting and important industrial examples. Thus the book concentrates on practical aspects rather than details of centrifugation theory.

Book Description
Centrifugal Separations in Molecular and Cell Biology focuses on the application of modern centrifugation technology in molecular and cell biology, including the separation and fractionation of biological particles by centrifugation on the preparative and analytical scales. The selection first covers the principles and practices of centrifugation and the bases of centrifugal separations. Discussions focus on the basic concepts of sedimentation theory, centrifugation methods, designing centrifugation experiments, care of centrifuges and rotors, and statistical estimation of molecular parameters. The book also ponders on the practical aspects of rate-zonal centrifugation, including gradient materials, density and viscosity of glycerol solutions, and resolution and gradient shape. The publication examines fractionations in zonal rotors and the quantitative aspects of rate-zonal centrifugation. The text then reviews isopycnic centrifugation in ionic media and analytical centrifugation. Topics include separation by isopycnic banding, large-scale preparative procedures, and density-gradient solutes. The selection is a valuable reference for readers interested in centrifugation technology.
