The phenomenon of electrophoresis is descriptively elucidated in this comprehensive book. Electrophoresis is the movement of electrically charged particles in a direct current electric field. Electrophoretic separation depends on differential rate of migration in the bulk of the liquid phase and has no concern with reactions occurring at the electrodes. In the early days, electrophoresis was carried out either in free solution or in supporting media such as paper, cellulose acetate, starch, agarose and polyacrylamide gel. Between 1950 and 1970, numerous techniques and instrumentation for electrophoresis were developed. This book discusses fundamentals on capillary electrophoresis and diverse application of electrophoresis in general. This book will prove valuable to readers who are interested in fundamentals as well as applications of electrophoresis in general.
