Organic Functional Group Analysis By Gas Chromatography

Monographs in Organic Functional Group Analysis, Volume 4: The Determination of Organic Peroxides focuses on the analytical chemistry of organic peroxides. The monograph first offers information on the compositions, properties, and reactions of lipid peroxides, polymers, and petrochemicals. The text then reviews the iodometric methods, including choice of solvents, reaction conditions, and titration with thiosulfate. The ferrous ion methods are also discussed. Considerations include choice of reagents and solvents and titration with titanous, dichromate, and mercurous ions. The book also focuses on titrimetric methods, including arsenious, stannous, and titanous methods, titration with anions, and sulfides and mercaptans. Numerical representations are provided. The text puts emphasis on colorimetric and polarographic methods. Polarographic techniques for peroxides; nature and concentration of peroxides; leuco base of methylene blue; and ferrous ions are described. The book also discusses paper, thin-layer, and gas chromatography. The monograph is an important guide for readers interested in the analytical chemistry of organic peroxides.

Organic Functional Group Analysis: Theory and Development attempts to symbolize the growth in functional groups analysis by using handpicked methods. Those methods are positioned to represent as many functional groups as possible. The book begins with the author referencing books about a quantitative organic analysis. Majority of the first few chapters highlight the oximation and carbonyl method, which support portions of Chapter 2 and the book's second half. The book then discusses the hydroxyl, amino, and alkoxysilanes groups. Chapters 3 and 4 showcase the strong analytical advantages in using base catalysis and acid catalysis with the same anhydride, while Chapters 5, 6, and 7 illustrate extremely useful functional group methods that have received impetus from research. The next chapters talk about the quantitative ring opening method and Diels-Alder addition method. Succeeding studies are about various compounds and its relevant subtopics. The text provides a very great reference for undergraduates and postgraduates of chemistry and its affiliated studies.

Chemical Methods in Gas Chromatography

A Practical Gas Analysis by Gas Chromatography provides a detailed overview of the most important aspects of gas analysis by gas chromatography (GC) for both the novice and expert. Authors John Swinley and Piet de Coning provide the necessary information on the selection of columns and components, thus allowing the reader to assemble custom gas analysis systems for specific needs. The book brings together a wide range of disparate literature on this technique that will fill a crucial gap for those who perform different types of research, including lab operators, separation scientists, graduate students and academic researchers. This highly practical, up-to-date reference can be consulted in the lab to guide key decisions about proper setup, hardware and software selection, calibration, analysis, and more, allowing researchers to avoid the common pitfalls caused by incorrect infrastructure. Shows, in detail, how valve configurations work, allowing readers to understand the building blocks of extremely complex systems Presents the complete infrastructure for setting up a gas analysis laboratory in a single source Includes a full chapter on practical analytical systems for analyzing various gas mixtures

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.

Gas chromatography (GC) is one of the most important types of chromatography used in analytical chemistry for separating and analyzing chemical organic compounds. Today, gas chromatography is one of the most widespread investigation methods of instrumental analysis. This technique is used in the laboratories of chemical, petrochemical, and pharmaceutical industries, in research institutes, and also in clinical, environmental, and food and beverage analysis. This book is the outcome of contributions by experts in the field of gas chromatography and includes a short history of gas chromatography, an overview of derivatization methods and sample preparation techniques, a comprehensive study on pyrazole mass spectrometric fragmentation, and a GC/MS/MS method for the determination and quantification of pesticide residues in grape samples.
