Cover; Further Titles for Chromatographers; Title Page; Copyright; Preface; Introduction; Part I: Fundamentals; 1.1 Chromatography; 1.2 Chromatographic Figures of Merit; 1.3 The Resolution of Two Peaks; 1.4 Reduced Parameters; 1.5 The Van Deemter Curve; 1.6 Peak Capacity and Number of Possible Peaks; 1.7 Statistical Resolution Probability: Simulation; 1.8 Statistical Resolution Probability: Example; 1.9 Precision and Accuracy of an Analytical Result; 1.10 Standard Deviation; 1.11 Variability of the Standard Deviation; 1.12 Uncertainty Propagation; 1.13 Reproducibility in Trace Analysis.

The third edition of this popular problem-solving guide for this widely-used method includes eleven completely new examples and several updated ones, adding up to over 100 potential pitfalls and errors in HPLC. Each example is presented on a double page with the text on the left-hand and a figure on the right-hand side, true to the motto ""a picture says more than a thousand words"". In addition, the author presents essential fundamentals as well as helpful strategies, such as equipment tests or quality assurance processes. A must-have resource for all those users without a background in an.
