Download or read book Principles and Applications of Gas Chromatography in Food Analysis written by Michael H. Gordon and published by Springer Science & Business Media. This book was released on 2013-03-08 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: The food analyst plays an important role in modern society. Stricter control over additives in food and concern about the effects of contamination of food by industrial and agricultural chemicals are among the developments which are leading to an increasing emphasis on detailed and accurate analysis of food. However. analysis of food is required for many reasons, including detection of toxic components, monitoring legislation, detecting adulteration, formulation of controlled diets, controlling formulation during product development and detecting changes in food during storage and processing. Foods comprise a complex mixture of components and food analysis requires efficient methods of separation with high sensitivity or specificity of detection. Although many food components are involatile or thermally labile and therefore not suitable for analysis by gas chromatography, other components are volatile and this technique is the preferred analytical method. Developments in methods of derivati zation, injector design and column technology have also extended the applicability of gas chromatography to the analysis of relatively involatile compounds.

Download or read book Qualitative Analysis of Flavor and Fragrance Volatiles by Glass Capillary Gas Chromatography written by Walter Jennings and published by Elsevier. This book was released on 2012-12-02 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: Qualitative Analysis of Flavor and Fragrance Volatiles by Glass Capillary Gas Chromatography deals with the application of glass capillary gas chromatography to qualitative analysis of flavor and fragrance volatiles. Topics range from gas chromatographic system requirements and retention indices to selective detectors, ancillary reactions, and gas chromatography-mass spectrometry. This text is comprised of six chapters; the first of which provides an overview of the use of glass capillary gas chromatography in qualitative analysis of flavor and fragrance volatiles. The discussion then turns to gas chromatographic system requirements with respect to columns, inlets, detectors, and temperature control. The reader is also introduced to the Kovats retention index system, which utilizes a logarithmic scale to describe the retention behavior of a compound relative to that of the n-paraffin hydrocarbons. The use of selective detectors, such as thermal conductivity, flame ionization, nitrogen-phosphorus, electron capture, and photoionization detectors in qualitative analysis, is also considered. The final two chapters focus on ancillary reactions in glass capillary gas chromatography and general considerations in gas chromatography-mass spectrometry, including interfacing. This book is intended primarily for researchers involved in studies of the volatile constituents of fragrances, food, and natural products.

Download or read book Analytical Reaction Gas Chromatography written by Viktor G. Berezkin and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most universal and effective method for the analysis of complex multicomponent mixtures of volatile substances is gas chromatography. However, there are a number of limitations asso ciated with the classical variation of this technique which retard its development and the further expansion of its application: 1) the identification of the components of a complex mix ture of unknown composition is in itself a complex and difficult problem, unless the homologous series of the component to be identified is known; 2) the overlapping of chromatographic peaks for several compounds makes it difficult, and in a number of cases impossible, to carry out qualitative and quantitative analysis of these components, and leads to the necessity of using several columns of different polarities or to the use of columns with very high efficiency; 3) the direct analysis of unstable and nonvolatile compounds is impossible; 4) the difficulty of quantitative chromatographic analysis using thermal conductivity detectors increases with the necessity of determining individual response (calibration) factors; the insensitivity of the flame ionization detector to a number of substances (inorganic gases) leads to the necessity of introducing additional operations (prelimi nary concentration of trace components) in connection with thermal conductivity detectors. vii viii FOREWORD The directed use of chemical conversion of the compounds analyzed usually makes it possible to remove the limitations cited above.
Download or read book Gas Chromatographic Analysis of Trace Impurities written by V. G. Berezkin and published by Springer. This book was released on 1995-12-31 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent scientific and industrial developments have demon strated the major effects (advantageous or otherwise) of trace components in compounds, which in commercial products may substantially affect the properties and the course of reactions, especially catalytic ones. Some of these problems (e.g., the pur ity of natural waters and air) have attracted the attention not only of specialists but also of society generally. It would be impossible to do research on trace components and contaminants if we did not have reliable rapid and sensitive methods of determining substances present in mixtures in minute concentrations. Gas chromatography is an effective method of purity testing. This book deals with analysis for trace components, together with the basic methods of gas chromatography that are used for the purpose. We have tried to reflect here the principal papers in this area appearing in the foreign literature and in Rus sian. Weare indebted to Plenum Pre~'B for the opportunity of pre senting this edition. Moscow September 1972 v Preface Gas -chromatographic analysis for impurities is presently a rapidly developing area in gas chromatography, because many practical topics give considerable importance to impurity analy sis. Progress in this analysis bas been such for volatile com pounds (and also for nonvolatile ones, when reactive gas chroma tography is used) that one can now be confident of solving most practical problems in this way. Commercial ionization detectors of high sensitivity and selectivity often allow one to detect impuri ties down to levels of parts in 109.

Download or read book Gas Chromatography written by A. B. Littlewood and published by Elsevier. This book was released on 2013-10-22 with total page 561 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gas Chromatography: Principles, Techniques, and Applications, Second Edition, is a general textbook on gas chromatography suitable for users of the technique and for research workers. It does not presuppose any knowledge of the subject. Starting with an introduction to gas chromatography, the first half of the book is primarily concerned with the ability of gas chromatography to perform separations. The theory of the operation and design of gas chromatographic columns—both packed and open-tube—is described in detail, and it is shown how columns may be designed so as to secure any desired separation. Separate chapters discuss the thermodynamics of solution and the kinetics of chromatography. The third quarter of the book deals with detectors, which are the means of obtaining quantitative analyses by gas chromatography. It also contains a description of the union of gas chromatography with other techniques, and some indication of the use of the more sophisticated methods of handling gas-chromatographic data. The last quarter of the book is a single chapter in a series of sections, each dealing with the chromatography of a particular class of chemical compound
