Available in PDF, EPUB and Kindle. Book excerpt: Dans un premier chapitre, nous examinerons les techniques d'identification qui utilisent les données de rétention. Dans un second chapitre, nous examinerons les renseignements qualitatifs qui peuvent être donnés par les détecteurs. Le troisième chapire sera consacré aux différentes méthodes physiques et chimiques de modification de l'échantillon, ainsi qu'aux tests chimiques d'identification. Nous terminerons cette mise au point en examinant brièvement le couplage de la C.P.G. (chromatographie en phase gazeuse) avec d'autres méthodes physiques d'analyse.

Available in PDF, EPUB and Kindle. Book excerpt: L'introduction d'une nouvelle technique dans notre laboratoire a nécessité le travail qui est présenté ici. Ce document a été fait dans le but de donner un aperçu de ce qu'est la chromatographie en phase gazeuse et de ses possibilités. Les références bibliographiques indiquent des ouvrages beaucoup plus complets où l'on pourra se référer pour toute documentation complémentaire. Après une descritpion de la technique chromatographique proprement dite, j'ai insisté sur la partie relative au traitement quantitatif de l'information issue du chromatographe en examinant successivement : l'enregistreur potentiométrique, les méthodes d'intégration qui en sont dépendantes. Ce dernier chapitre, constitué par les intégrateurs électroniques, a été volontairement développé afin de rendre cet appareil plus familier et d'en montrer les avantages et les limites : l'utilisation optimale d'un appareil nécessitant une pleine compréhension de son principe. Enfin, j'ai donné un aperçu des applications de la chromatographie en phase gazeuse faites dans notre laboratoire, à savoir : l'analyse des agents tensi-actifs de collection.
Download or read book Quantitative Gas Chromatography for Laboratory Analyses and On Line Process Control written by G. Guiochon and published by Elsevier. This book was released on 1988-06-01 with total page 811 pages. Available in PDF, EPUB and Kindle. Book excerpt: Here is an invaluable new book on quantitative gas chromatography which explains how the method can - or should - be used for accurate and precise analysis. Gas chromatography is firmly established as one of the few major methods for the quantitative analysis of complex mixtures. It is fast, accurate and inexpensive, with a broad range of applications. It has however become very complex and involved: over 200 stationary phases, more than 10 detector principles and several very different column types are available from among the catalogs of over 100 manufacturers and major retailers. The progressive changes in the nature of gas chromatography have created new needs for information which are not satisfied by the literature presently available.This book provides a complete discussion of all the problems involved in the achievement of quantitative analysis by gas chromatography, whether in the research laboratory, in the routine analysis laboratory or in process control. For this reason the presentation of theoretical concepts has been limited to the essential, while extensive explanations have been devoted to the various steps involved in the derivation of precise and accurate data. This starts with the selection of the instrumentation and column, continues with the choice of optimum experimental conditions, then calibration and ends with the use of correct procedures for data acquisition and calculations. Finally, there is almost always a way to reduce errors and an entire chapter deals with this single issue. Numerous relevant examples are presented.The first part of the book presents the theoretical background, simple enough to be understood by all analytical chemists, but still complete and up-to-date. It discusses the problems of flow dynamics, retention and band broadening. The changes in band profile associated with column overloading are explained without much recourse to mathematics. The second part describes the gas chromatograph and discusses the properties of each of its parts: gas flow and pressure controller sampling system, oven, column switching valves, detectors. The different implementations, their advantages and drawbacks are discussed and compared. In addition, three chapters present packed column technology, open tubular column technology and some sophisticated new phase systems, respectively. The new phase systems described use adsorbents, modified by coating or grafting organic phase, and carrier gases containing vapors which are sorbed by the stationary phase and modify it, such as steam. The third part discusses the applications in qualitative and quantitative analysis. Calibration, peak integration, sources of errors arising from the various parts of the instrument as well as from the measurement process itself are carefully described in four detailed chapters. Methods to carry out accurate and precise analysis are presented. A last chapter is devoted to process control analysis and gives a number of detailed examples of applications. A lexicon explaining the most important chromatographic terms and a detailed index complete the book.This is a book which no chemical analyst should be without. It should be on the library shelf of all universities, instrument companies and any laboratory and plant where gas chromatography is used.

This book was released on 1995 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: La première partie de ce travail concerne l'application de la chromatographie en phase supercritique à l'analyse de produits pétroliers, notamment pour réaliser une méthode de distillation simulée. Des solutions aux difficultés rencontrées sont proposées. Dans la seconde partie, on réalise l'étude et la mise au point de la détection d'émission atomique couplée à la chromatographie en phase gazeuse. Cette technique est appliquée à l'analyse qualitative de nombreux produits pétroliers. L'analyse quantitative révèle quant à elle la nécessité d'améliorer le contrôle des différents débits des gaz utilisés. La perspective du couplage de ces deux techniques est ensuite envisagée et débattue
