Author: David G Watson
An introductory text, written with the needs of the student in mind, which explains all the most important techniques used in the analysis of pharmaceuticals – a key procedure in ensuring the quality of drugs . The text is enhanced throughout with keypoints and self-assessment boxes, to aid student learning.
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.
