Download or read book Interpr tation des spectres de masse en couplage GC MS cours et exerices corrig s written by BOUCHONNET Stéphane and published by Lavoisier. This book was released on 2012-09-04 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: C’est avec une réelle volonté didactique que cet ouvrage aborde l’interprétation des spectres de masse pour confirmer ou élucider des structures chimiques. Les publications scientifiques dédiées à la spectrométrie de masse sont souvent complexes et présentent une approche très théorique, souvent difficile à comprendre et à mettre en pratique. Ce livre se fait fort, grâce à sa simplicité et à sa démarche ancrée dans la pratique, d’offrir aux débutants comme aux spécialistes du domaine, les clés de cette technique. Un premier chapitre présente des rappels de chimie organique nécessaires à une bonne compréhension des réactions impliquées. Dans un deuxième chapitre, les mécanismes de formation et de dissociation des ions sont détaillés : ruptures simples et réarrangements, fragmentations secondaires, etc. Ces mécanismes sont illustrés de nombreux exemples concrets. La seconde partie de cet ouvrage propose une cinquantaine d'exercices corrigés permettant d'acquérir maîtrise et autonomie. À la fois manuel universitaire et guide pratique quotidien, L’interprétation des spectres de masse en couplage GC-MS constitue une référence pour tous les utilisateurs de couplage GC-MS tels que les ingénieurs, techniciens, chercheurs, étudiants, etc., débutants ou confirmés, désireux d'interpréter judicieusement leurs spectres de masse. Outre l'élucidation structurale, la compréhension des mécanismes qui régissent l'interprétation des spectres permet l'amélioration des méthodes analytiques et la fiabilisation des résultats.
Download or read book Organic Micropollutants in the Aquatic Environment written by A. Bjørseth and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 523 pages. Available in PDF, EPUB and Kindle. Book excerpt: The "Fourth European Symposium on Organic Micropollutants in the Aquatic Environment" was held in Vienna (Austria) from 22 to 24 October 1985. The Symposium was organized wi thin the framework of the Concerted Action COST 641* which is included in the Third R&D Programme on the Environment of the Commission of the European Communities. The aim of the Symposium was to review recent scientific and technical progress in the area of organic micropollutants in the aquatic environment and to present relevant research papers related to analytical methodologies, transformation reactions and transport of organic micropollutants in water, and water treatment processes. A special session was devoted to theoretical aspects and future acti vi ties. Furthermore, special poster sessions were organized where original contributions were presented. This book presents the Proceedings of the Symposium including all review papers, presentations of research papers and extended versions of all posters. We believe that these Proceedings provide a good overview of the activities in this field in Europe. We are confident that it will constitute a valuable contribution to the understanding and solution of the problems posed by organic micropollutants in the aquatic environment. The Commission of the European Communi ties whishes to express its grati tude to the co-organizers of the Symposium, Bundesministerium fUr Gesundheit und Umweltschutz, Wien, and Der Osterreichische Wasserwirtschaftsverband.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides key information about the instrumental analytical methods which are the most used in quantitative analysis. A theoretical knowledge of each method is discussed. The methods are illustrated with several examples covering a wide range such as pharmacy, biochemical, environmental and agrochemicals analysis. It is structured into three parts: the first one focuses on separation methods, the second covers the spectroscopic ones and the third part develops the thermal and the radiochemical methods.

Download or read book FAO INFOODS Food Composition Table for Western Africa 2019 Table de composition des aliments FAO INFOODS pour l Afrique de l Ouest 2019 written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2020-02-20 with total page 556 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food composition data are useful throughout the food system for nutrition-sensitive agriculture, improved processing methods that ensure greater nutrient retention in foods, nutrition labelling, and to inform, educate and protect consumers through food-based dietary guidelines, nutrition education and communication, and legislation. The FAO/INFOODS Food Composition Table for Western Africa (WAFCT 2019) is an update of the West African Food Composition Table of 2012, which lacked some important components, foods and recipes. WAFCT 2019 contains almost three times as many food entries and double the number of components, with increased overall data quality. Many of the data points from WAFCT 2012 have been replaced with better data – mostly analytical data from Africa, with a special emphasis on Western Africa. These improvements are essential to understanding the nutrient composition of foods in the region and to promoting their appropriate use. WAFCT 2019 is the result of four years of collaboration among INFOODS network researchers in Africa and the Nutrition and Food Systems Division of FAO, and was developed as part of the International Dietary Data Expansion (INDDEX) Project, implemented by Tufts University’s Gerald J. and Dorothy R. Friedman School of Nutrition Science and Policy, with funding from the Bill & Melinda Gates Foundation. These new data from WAFCT 2019 will support further research towards an expanded and improved evidence base and will support better, more informed decisions and effective policies and programmes for improved nutrition in Africa.

Download or read book Conservation Science for the Cultural Heritage written by Evangelia A. Varella and published by Springer Science & Business Media. This book was released on 2012-12-15 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conservation Science is a rather innovative application of instrumental analysis with steadily increasing importance. Although the first attempts for preserving material from the cultural heritage on a scientific basis are found in the 19th century pioneer chemistry years, only the use of sophisticated physicochemical techniques results in effective identification and deterioration studies of monuments and objects, and in reliable intervention procedures. This volume allows to gain solid knowledge and improved skills on the ways separation schemes and diagnostic methodologies are applied in the safeguarding and authentication of tangible works of art; as well as on the modes of implementing novel safeguarding practices built on well-established principles – such as the use of laser in the decontamination of objects. All techniques are covered at a state-of-the-art level; while selected applications permit addressing major groups of materials and artefacts. Conservation Science is nowadays taught at master’s level in all developed countries, and museum laboratories increasingly adopt scientific approaches in their restoration initiatives. The book is intended as a valuable tool for students and professionals active in these frames. In addition, it provides an indispensable manual for participants in the specialized intensive courses, which are systematically offered by the authors under the auspices of the relevant European network.
