This book examines challenges and applications, as well as principles of capillary electrophoresis. Some of the topics discusses include the preparation and application of photosensitive capillary electrophoresis coatings; the application of capillary zone electrophoresis to trace analyses of inorganic anions in seawater; theoretical principles and applications of high performance capillary electrophoresis; and the application of capillary zone electrophoresis methods for polyphenols and organic acids to separate different extracts.
