The data generated using analytical methods is essential for many of the critical decisions made in the pharmaceutical industry. To be confident in the reliability of this data it is crucial that the methods are fit for purpose. Analytical method validation is the process of demonstrating that a method is suitable for its intended use. This two day course provides a detailed explanation of how analytical methods are validated, enabling a full understanding of method performance characteristics and associated statistics, and how they are applied to the techniques used for analysing drug related samples. This knowledge will enable informed interpretation of the current regulatory guidance on validation, namely ICH Q2(R1). The approach of this course is to focus on the principles of method validation thereby enabling application to different types of samples and analytical techniques. Case studies are employed to allow consideration of real life scenarios. Examples relating to small molecule drug substances and formulated products, and to physiochemical methods for biotechnological/biological products, are included. Particular attention is paid to the most common analytical techniques used for pharmaceutical analysis, e.g., High Performance Liquid Chromatography (HPLC).
