The knowledge of metal ion speciation is essential for predicting the exact toxicities of metal ion species in the environment. Metal ions can exist in various oxidation states, each of which possesses different physical and chemical properties as well as exhibit varying toxicities. Often, toxicity data is unreliable because it is based on metal ion concentration measurements that fail to identify a dominant species either more or less harmful than the average. Instrumental Methods in Metal Ion Speciation provides analytical techniques and experimental methodologies for determining the concentration of the different physicochemical forms of metal ions in environmental and biological samples, leading to more accurate measurements of actual toxicity.The authors introduce the principles of metal ion speciation and discuss important analytical techniques such as gas and liquid chromatography, capillary electrophoresis, and both electrochemical and radiochemical methods used to determine concentration and composition. They present a range of liquid chromatographic approaches, including capillary electrochromatography and high-performance, ion, ion pair, micellar electrokinetic, size exclusion, chiral, and supercritical fluid chromatographies for all metal ion species. Comprehensive in scope, the text covers the sources, distribution, toxicity, biotransformation, and biodegradation of each metal ions species as well as extraction methods, sample preparation, and experimental optimization techniques that can be useful in designing future experiments. Instrumental Methods in Metal Ion Speciation is a unique and valuable source of reference for scientists, academics, and researchers involved in analytical, biological, pharmaceutical, and environmental chemistries, as well as material industries, geochemistry, agriculture, biotechnology, and occupational safety and regulations.

Quality and reliability are central to success in every discipline, but perhaps nowhere are they more important or more interconnected than in the practice of analytical chemistry. Here, although reliable analytical information implies quality, not all "quality" information proves reliable.Quality and Reliability in Analytical Chemistry examines the various factors affecting these parameters in each step of the analytical process:The Sample: Investigate the reliability of the sample, including its history and homogeneity.The Method: See the connection between reliability and the selection of analytical methods for environmental, food, and clinical analyses.The Instruments: Examine the relationship between reliability and your instrumentation.Data Processing: Consider the importance of chemometrics in the reliability of data processing.Automation: Explore automation of the analytic process through discussion of its parameters - rapidity, reproducibility, flexibility, and reliability.Standards and Standardization: Understand how quality and reliability cannot be assured without using standards for measurement and how only reliable methods can be standardized.The goal of the analytic process is to obtain high quality information with high reliability. Quality and Reliability in Analytical Chemistry helps you meet that goal and thereby satisfy your quality assurance and quality control requirements.

Vor allem enantiomer selektiver Trenn- und Analyseverfahren für zahlreiche chirale Umweltschadstoffe werden kritisch beschrieben. Im Vergleich zur ersten Auflage von 2001 wurde die Neuauflage vollständig umstrukturiert, und eine Fülle neuer Materialien hinzugefügt, um der fachlichen Weiterentwicklungen der letzten 20 Jahre Rechnung zu tragen. Das Buch berichtet über moderne enantiomer selektive Trennverfahren, einschließlich enantiomer selektiver Chromatographietechniken, die sogar erfolgreich im Weltraum während der ESA-Rosetta-Mission getestet wurden.Die Autoren stellen dar, warum das Thema chirale Umweltschadstoffe in den letzten Jahrzehnten noch wichtiger geworden ist. In den letzten Jahren wurden viele neue chirale bioaktive Verbindungen für Anwendungen in Medizin, Landwirtschaft und Technische Verbraucherprodukte entwickelt. Umweltanalysen zeigen, dass Spuren dieser Verbindungen inzwischen auch in der Umwelt zu finden sind. Die Autoren erläutern ausführlich, dass das Prinzip Chiralität heutzutage ein sehr wichtiger Faktor für die Bewertung der Bioaktivität anthropogener Schadstoffe sein kann.In diesem Buch finden Leser eine detaillierte Einführung in das Thema. Diese Einführung beinhaltet auch alle wichtigen Aspekte, ausgehend von der Einführung neuer enantiomer selektiver analytischer Methoden neu entdeckter chiraler Umweltschadstoffe bis hin zu Aspekten der Umwelt- und Humantoxikologie. Unter anderem werden sowohl Methoden zur enantiomer selektiver Risikobewertung ausgewählte chirale Stoffe aber auch bedeutende Aspekte des Klimawandels näher beleuchtet.Das Buch ist daher ein Muss für alle, die im Bereich chiraler Umweltschadstoffe arbeiten. Außerdem kann es ist auch für Lehrzwecke in spezialisierten Bachelor- und Mastergradskursen sowie für fortgeschrittene analytische Chemie, pharmazeutische Analytik oder Umweltchemie von Nutzen sein.
