This introductory text highlights the most important aspects of a wide range of techniques used in the control of the quality of pharmaceuticals. Written with the needs of the student in mind, this clear, practical guide includes self-testing sections with arithmetical examples and tests to help students brush up on their arithmetical skills in an applied context. Features Includes worked calculations to demonstrate mathematics in use for pharmaceutical analysis. Focuses on key points rather than a large number of facts to help readers really understand the field as well as pass exams. Includes self-assessment, focussing on simple arithmetical calculation results from analytical data. New to this edition Mass spectrometry completely rewritten to reflect extensive changes in the instrumentation. High-pressure liquid chromatography extensively reworked to cover recent developments in ultra high-pressure liquid chromatography. Nuclear magnetic resonance spectroscopy rewritten by an expert in this complex analytical technique. Thoroughly updated throughout to provide a succinct, expert account of the most frequently used techniques in pharmaceutical quality control.
