Since the original text published in 2001, there have been significant advances in various analytical techniques and their applications. Each chapter of the new book is rewritten by a contemporary expert in the field, who explains the basic principles of the technique and highlights any recent technical advances in instrumentation or methods of analysis. Where appropriate and fully integrated into the chapters, applications are used to highlight particular operating principles or methods of interpretation. All chapters have been reviewed to ensure consistency and accuracy of nomenclature and descriptions thus ensuring the quality of the book. Primarily aimed at undergraduate courses and the chemical industry where this technique is being used, it may also find a use with instrument manufacturers where they are introducing this method.
