Reihe: Chromatographic Science Series

This book focuses on a relatively new approach to chemical analysis in general and to separation science in particular. It covers the combination of thin-layer chromatography (TLC) and high performance TLC (HPTLC), one of the most simple, cost-effective, and well-performing techniques for determining complex mixtures of compounds along with mass spectrometry (MS), a sophisticated and relatively expensive spectrometric technique that enables rapid identification of separated chemical species. In addition to that, the book covers electrophoretic – MS methods and applications.

Zielgruppe

This book is intended for separation science practitioners at all levels of professional expertise (from junior and senior class undergraduate students to graduate school academics as well as industrial and regulatory analytical chemists). It would be particularly useful to those working in traditional Chinese and Indian herbal medicine, food analysis, and forensic analysis; as well as to clinical laboratory personnel working in the medical diagnostics area.
