Chemical Analysis: Modern Instrumentation Methods and Techniques 2nd ed Completely revised and updated, Chemical Analysis: Second Edition is an essential introduction to a wide range of analytical techniques and instruments. Assuming little in the way of prior knowledge, this text carefully guides the reader through the more widely used and important techniques, whilst avoiding excessive technical detail. * Provides a thorough introduction to a wide range of the most important and widely used instrumental techniques * Maintains a careful balance between depth and breadth of coverage * Includes examples, problems and their solutions * Includes coverage of latest developments including supercritical fluid chromatography and capillary electrophoresis Foreword to the first English edition.
