Practical Gas Chromatography
Gas chromatography continues to be one of the most widely used analytical techniques, since its applications today expand into fields such as biomarker research or metabolomics. This new practical textbook enables the reader to make full use of gas chromatography. Essential fundamentals and their implications for the practical work at the instrument are provided, as well as details on the instrumentation such as inlet systems, columns and detectors. Specialized techniques from all aspects of GC are introduced ranging from sample preparation, solvent-free injection techniques, and pyrolysis GC, to separation including fast GC and comprehensive GCxGC and finally detection, such as GC-MS and element-specific detection. Various fields of application such as enantiomer, food, flavor and fragrance analysis, physicochemical measurements, forensic toxicology, and clinical analysis are discussed as well as cutting-edge application in metabolomics is covered.
Quantification in LC and GC
Closing a gap in the current literature by addressing the evaluation and quality assessment of raw data, this practice-oriented guide is clearly divided into three parts. The first describes basic considerations of chromatographic data quality, common errors and potential pitfalls in reading out and quantifying the data. Part two systematically covers the most important chromatographic methods as well as the specific requirements for obtaining good chromatographic data. The final part looks at data quality from the perspective of those regulatory authorities demanding certain standards in data quality, describing in detail best practices. Written with the practitioner in mind, the text not only teaches the mathematical basics but also provides invaluable advice.
Drying of Herbs, Spices, and Medicinal Plants
Drying is a key operation in processing of many plant-based foods and medicines for the purpose of preservation and retention of key attributes and active compounds. Therefore, it is essential to select suitable drying techniques to ensure a product is processed under optimal operating conditions. Drying of Herbs, Spices, and Medicinal Plants presents processing aspects of these three major global agricultural commodities. It offers an insight into the drying and product quality of herbs, spices, and medicinal plants, such as drying characteristics, equipment selection, physiochemical analyses, quality improvement, product development, storage, and shelf life as well as future developments. ...
Chromatography
Leading researchers discuss the past and present of chromatography More than one hundred years after Mikhail Tswett pioneered adsorption chromatography, his separation technique has developed into an important branch of scientific study. Providing a full portrait of the discipline, Chromatography: A Science of Discovery bridges the gap between early, twentieth-century chromatography and the cutting edge of today’s research. Featuring contributions from more than fifty award-winning chromatographers, Chromatography offers a multifaceted look at the development and maturation of this field into its current state, as well as its importance across various scientific endeavors. The coverage inc...
Handbook of GC/MS
This is the first comprehensive reference work for GC/MS now in its second edition. It offers broad coverage, from sample preparation to the evaluation of MS-Data, including library searches. Fundamentals, techniques, and applications are described. A large part of the book is devoted to numerous examples for GC/MS-applications in environmental, food, pharmaceutical and clinical analysis. These proven examples come from the daily practice of various laboratories. The book also features a glossary of terms and a substance index that helps the reader to find information for his particular analytical problem. The author presents in a consistent and clear style his experience from numerous user workshops which he has organized. This is a thoroughly revised and updated English edition based on an edition which was highly successful in Germany.
Analytiker-Taschenbuch
Das Analytiker-Taschenbuch bietet mit seinen sehr aktuellen und praxisbezogenen Beiträgen zu Grundlagen, Methoden und Anwendungen analytisch-chemischer Verfahren eine wahre Fundgrube für alle Praktiker in den Bereichen Analytische Chemie, Lebensmittel- und Umweltchemie, Klinische Chemie, Werkstofforschung und Biotechnologie. Die komprimierte Darstellung und die bewußt ausgewählten Literaturangaben ermöglichen dem Spezialisten ein effizientes Einarbeiten und Adaptieren der Methodik und dem Nicht-Spezialisten einen schnellen Überblick. Den Schwerpunkt des Bandes bilden die analytische Echtheitsbewertung natürlicher Duft- und Aromastoffe mittels Isotop-Ratio-MS und CGC, die Kapillarelektrophorese sowie Elutions- und Extraktionsverfahren für mobile Kontaminanten in Feststoffen.
Chromatogramme richtig integrieren und bewerten
Stavros Kromidas und Hans-Joachim Kuss schließen mit ihrem Autorenteam aus erfahrenen Experten eine wichtige Lücke in der Analytik-Literatur: Sie stellen prägnant und nachvollziehbar den Weg von den Rohdaten zum bewerteten Ergebnis vor. Das ist besonders wichtig für gesetzlich relevante Messungen, z. B. in der Pharma- und Nahrungsmittelanalytik, denn wer hier Fehler macht, erzeugt trotz korrekter Messdaten falsche Informationen. Und auf die gebräuchlichen Auswerteprogramme ist nicht immer Verlass.
