Over more than two decades this book has established itself as the first choice for growing numbers of students and practising analysts who require a well-written and concise overview of the principles and practice of analytical chemistry. Recurring themes are improvement in medicine and the environment, the I.T. revolution and its continuing impacts on both analytical methodology and data handling. The successive editions of Principles and Practice of Analytical Chemistry have kept pace with the associated developments in the subject. Significant changes encompass strengthening of the coverage of data handling, together with new material covering rapidly developing subject areas of molecular spectrometry, atomic spectrometry, and separation techniques. Answers to the self- learning problems and exercises are also included. All sections of the book have been fully reviewed and updated as appropriate. The new edition of the book continues to provide a sound and broad base for the study of analytical chemistry by undergraduate and postgraduate students, and to be a useful resource for practising analysts, seeking a summary of the principles of techniques and methods.
