Analytical techniques based on separation processes, such as chromatography and electrophoresis, are finding a growing range of applications in chemical, pharmaceutical and clinical laboratories. The Wiley Separation Science Series provides the analyst in these laboratories with well focused books covering individual techniques, so that they can be applied more efficiently and effectively to contemporary analytical problems. In biotechnology, biochemistry and molecular biology, the characterization and analysis of biomolecules such as proteins, oligosaccharides and nucleic acids are of great importance. High performance liquid chromatography (HPLC) has become one of the key analytical tools in these fields, providing rapid purification and quantitative analysis of biomolecules. High Performance Liquid
