Organic Trace Analysis by Liquid Chromatography


Book Description

Organic Trace Analysis by Liquid Chromatography focuses on high-performance liquid chromatography in the field of formulations analysis, which includes quality control of pharmaceutical preparations, pesticide formulations, cosmetics, and food colors. This book explores the application of liquid chromatography to trace analysis. Organized into 10 chapters, this book starts with an overview of the special requirements of liquid chromatography for trace analysis. This text then compares the approach to gas chromatography and formulations analysis, noting the significant difference. Other chapters consider the liquid chromatography equipment and examine the best types and conditions of instrumentation suitable for trace analysis. This book discusses as well the chromatography theory and includes descriptive accounts of the principles of the different forms of chromatography. The final chapter describes the typical approaches that are used for trace analysis. This book is a valuable resource for analysts engaged in the determination of trace organics in many various substrates.







Organic Trace Analysis


Book Description

Organic contaminants even in very low concentrations can have toxic and ecotoxic effects on exposed organisms. Detection and quantification of such trace amounts in diverging matrices (e.g., water, air, soil, food, tissue, organisms) is challenging and great carefulness and strategic thinking is needed to get reliable results along the way from taking samples up to the final analysis. In the 2nd edition, besides revisions of existing chapters, new analytical technologies and recent application examples are presented: non-target mass spectrometric analysis, trace analysis of per- and polyfluoroalkylated "forever chemicals", organophosphorus esters (nerve agents), and micro- and nanoplastic particles in the environment. Students will learn about peculiarities and state of the art organic trace analysis and acquire basic and advanced principles of statistical evaluation of analytical results quality control strategies and good laboratory practices sampling techniques from various matrices sample treatment, enrichment and clean-up techniques chromatographic analyses including hyphenated techniques, and spectroscopy as well mass spectrometry and bioanalytical tools. An extended chapter on selected applications will transfer the theoretical understanding into applied scientific problems. Students will profit from a comprehensive and state of the art overview of organic trace analyses and from an extensive collection of relevant literature.
