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 Applications of Gas Chromatography written by Adrianna Coty and published by . This book was released on 2016-04-01 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gas chromatography is a term used to describe the group of analytical separation techniques used to analyze volatile substances in the gas phase. In gas chromatography, the components of a sample are dissolved in a solvent and vaporized in order to separate the analyses by distributing the sample between two phases: a stationary phase and a mobile phase. The mobile phase is a chemically inert gas that serves to carry the molecules of the analyze through the heated column. Gas chromatography is one of the sole forms of chromatography that does not utilize the mobile phase for interacting with the analyze. The stationary phase is either a solid adsorbent, termed gas-solid chromatography (GSC), or a liquid on an inert support, termed gas-liquid chromatography (GLC). Helium remains the most commonly used carrier gas in about 90% of instruments although hydrogen is preferred for improved separations. This inert gas goes through a glass column packed with silica that is coated with a liquid. Materials that are less soluble in the liquid will increase the result faster than the material with greater solubility. The purpose of this book entitled Applications of Gas Chromatography is to provide a better understanding on its separation and measurement techniques and its application. Since chromatography techniques are separating and analyzing methods, this book will help other researchers and young scientists to choose a suitable chromatography technique. Furthermore, this book illustrates the newest challenges in this area. This valuable book aims to provide a connection between various chromatography techniques and different processes.

Download or read book Chromatography and Its Applications written by Sasikumar Dhanarasu and published by BoD – Books on Demand. This book was released on 2012-03-16 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chromatography is a powerful separation tool that is used in all branches of science, and is often the only means of separating components from complex mixtures. The Russian botanist Mikhail Tswett coined the term chromatography in 1906. The first analytical use of chromatography was described by James and Martin in 1952, for the use of gas chromatography for the analysis of fatty acid mixtures. A wide range of chromatographic procedures makes use of differences in size, binding affinities, charge, and other properties. Many types of chromatography have been developed. These include Column chromatography, High performance liquid chromatography (HPLC), Gas chromatography, Size exclusion chromatography, Ion exchange chromatography etc. In this book contains more details about the applications of chromatography by various research findings. Each and every topics of this book have included lists of references at the end to provide students and researchers with starting points for independent chromatography explorations. I welcome comments, criticisms, and suggestions from students, faculty and researchers.
