Описание: 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.
Описание: This book describes the analytical approach to testing over 160 important dietary supplement ingredients. In addition to the methods, there is significant guidance provided on how to develop, modify, and improve testing techniques. The procedures in this book include some of the most modern technologies that are available in the laboratory today. These basic principles of method development and troubleshooting can be implemented for food and food safety testing, drug development research, and agricultural areas. The contents of this book contain a very comprehensive collection of valuable analytical tools.
Описание: There is a growing need for high-throughput separations in food and environmental research that are able to cope with the analysis of a large number of compounds in very complex matrices.

Описание: Gas Chromatography: History, Methods and Applications focuses on the main applications of gas chromatography in clinical and forensic toxicology, mainly in the determination of drugs of abuse including the new psychoactive substances in several types of biological matrices. The authors go on to investigated the analysis of gaseous or volatile substances using sensor gas chromatography equipped with a semiconductor gas sensor detector. The simplicity, ease of handling, and high sensitivity of this method allow results to be obtained rapidly, which may provide valuable information for forensic diagnosis. This compilation addresses the way in which food adulteration practices are potentially harmful to human health and so food safety and authenticity constitute an important issue in food chemistry. The chemical composition of foodstuffs is an excellent indicator of quality, origin, authenticity and/or adulteration. The concluding study aims to determine the organic compounds of vinasse through gas chromatography-mass spectrometry GC-MS. Vinasse is a byproduct of ethanol and poses long-term risk to public health because of its persistent and toxic nature.

Описание:
Planar Chromatography-Mass Spectrometry focuses on a relatively new approach to chemical analysis in general, and to separation science in particular. It is the first book to systemically cover the theoretical background, techniques, instrumentation, and practical applications of planar chromatography-mass spectrometry as a hyphenated tool of analytical chemistry. It also examines the high and as-yet unexploited potential of planar chromatography-mass spectrometry for analytical use in scientific investigations.
This book overviews the combination of planar chromatography, a relatively simple and cost-effective separation step for determining complex mixtures of compounds, with mass spectrometry, an efficient, highly instrumental, and relatively expensive technique that enables rapid identification of separated chemical species. It covers electrophoretic-mass spectrometry methods and applications, which are considered planar chromatographic techniques and are increasingly being exploited in proteomic and molecular biology studies as well as for medical diagnostic purposes. It also provides a selection of applications, such as drug control and forensic and food analysis, including more difficult substances such as carbohydrates and lipids.
The book advocates growth in using planar chromatography-mass spectrometry in laboratories that have appropriate equipment but have not yet employed the techniques in combination. It also describes the use of a relatively inexpensive commercial system that can be adopted by laboratories currently working without the coupled methodology. Aiming to improve power and efficiency when other analytical methods are inadequate, Planar Chromatography-Mass Spectrometry encourages separation science practitioners in academia and industry to combine the two methods for enhanced results.
