Chromatography has been developed as a powerful and rapid technique for the separation of compounds with highly similar molecular characteristics, even from complicated matrices. Due to their excellent separation characteristics and Versatility, chromatographic methods have found growing acceptance and application in environmental protection for residue analysis in air, ground and surface waters, sewage, sludge, soil matrices, etc The book will be of interest to analytical chemists in legalisation and research and to analytical control specialists, as well as to researchers and students.
Chromatographic Analysis of the Environment, Third Edition is a detailed handbook on different chromatographic analysis techniques and chromatographic data for compounds found in air, water, soil, and sludge. Taking on a new perspective from previous editions, this third edition discusses the parameters of each environmental compartment in a consistent format that highlights preparation techniques, chromatographic separation methods, and detection methods. Most of the data are compiled in tables and figures to elucidate the text as needed. Separate chapters approach specific aspects of sampling methods especially designed for environmental purposes, quantification of environmental analytes in difficult matrices, and data handling. The second part of the book focuses on the analysis of hazardous chemicals in the environment, including volatile organic carbons (VOCs), polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), and endocrine-disrupting chemicals (EDCs). In addition, the authors feature information on compounds such as phosphates, organic acids, halogenated VOCs, amines, and n-ntirosamines, isocyanates, phthalate esters, and humic substances. Presenting important theoretical and practical aspects from sample collection to laboratory analysis, Chromatographic Analysis of the Environment, Third Edition is a unique resource of chromatographic techniques, data, and references that are useful to all scientists involved in the analysis of environmental compounds.

Gas Chromatographic Environmental Analysis ist die erste wirklich komplette, aktuelle und einheitliche Darstellung der analytischen Techniken der Umweltchemie in Buchform. Das Buch beschreibt die Grundlagen der Gaschromatographie in der Umweltuntersuchung. Nach einer Einführung in die Gaschromatographie und einer kritischen Bewertung der verschiedenen Säulentypen beschreibt der Autor sorgfältig die notwendige Meßapparatur. Besonderes Augenmerk gilt der Einspritzung sowie den Nachweis- und Kalibrierungssystemen. Ein Akzent liegt auf der Spurenanalytik, die wichtig ist z.B. für die Erkennung von Fluorkohlenwasserstoffen in der Atmosphäre. Daneben werden auch andere Techniken wie HPLC und Massenspektrometrie vorgestellt, um so ein vollständiges Bild der Umweltanalytik von heute und morgen zu geben. Da das Buch für Chemiker und analytische Chemiker sowohl in Forschung als auch Industrie, für Verfahrenstechniker, Umweltbiologen und -geologen geschrieben ist, beschäftigt sich Gas Chromatographic Environmental Analysis besonders mit den Methoden, die in den USA und anderen hochindustrialisierten Staaten eingeführt sind. Damit ist es eine willkommene Bereicherung für die Bibliotheken von chemischen Betrieben, Verwaltungen, Universitäten und Forschungseinrichtungen.
Sample preparation is an essential step in many analyses. This book approaches the topic of sample preparation in chromatography in a methodical way, viewing it as a logical connection between sample collection and analytical chromatography. Providing a guide for choosing the appropriate sample preparation for a given analysis, this book describes various ways to process the sample, explaining the principle, discussing the advantages and disadvantages, describing the applicability to different types of samples, and showing the fitness to specific chromatographic determinations. The first part of the book contains an overview of sample preparation showing its relation to sample collection and to the core chromatographic analysis. The second part covers procedures that do not use chemical modifications of the analyte and includes methods for sample dissolution, concentration and cleanup designed mainly for modifying the initial matrix of the sample. This part starts with conventional separations such as filtration and distillation and finishes with more advanced techniques such as solid phase extraction and electroseparations. The third part gives a description of the chemical modifications that can be performed on a sample either for fractionation purposes or to improve a specific property of the analyte. This part includes derivatizations, polymer chemical degradations, and pyrolysis.
