Capillary Electrophoresis: Principles and Practice

Capillary electrophoresis (CE) is a brand-new analytical method with the capability of solving many analytical problems very fast and economically. CE will be implemented in almost every analytical laboratory in industry, service units and academia in the near future, the most important fields of CE application being pharmaceutical and biochemical research and quality control. The authors have exhaustive practical experience in the application of CE methods in the pharmaceutical industry and provide the reader with a comprehensive treatment of this method. The main focus is on how to apply the method and how to solve problems in the laboratory. Physico-chemical theory is dealt with in depth where necessary to understand the underlying separation mechanisms or the influence of different instrumental parameters. An addendum includes tables on the preparation of buffers and recommended further reading.
