10 Validation of analytical methods using capillary electrophoresis

Abstract This chapter deals with the validation of capillary electrophoresis (CE) methods. It describes the various validation characteristics, namely accuracy, precision, specificity, detection limit, quantitation limit, linearity, and range in accordance with the official guidelines. Practical aspects related to the calculation of these parameters and factors affecting them in CE analysis have also been described. Validation requirements have been described according to the goal of the method. The chapter contains numerous tables and diagrams to illustrate these ideas. It also covers other related aspects such as instrument qualification, revalidation, and method transfer.
