Available in PDF, EPUB and Kindle. Book excerpt: La chromatographie en phase liquide à haute résolution s'est imposée aussi bien en analyse organique et biochimique qu'en analyse inorganique avec le développement prodigieux de la chromatographie ionique. Depuis quelques années, la chromatographie en phase supercritique, intermédiaire et complémentaire entre les chromatographies en phases liquide et gazeuse, pénètre les services de chimie analytique ; c'est pourquoi elle a été incluse dans cet ouvrage. Ces développements résultent des progrès conjoints de l'appareillage qui atteint aujourd'hui un haut degré de perfection, et des concepts qui permettent une bonne compréhension des mécanismes régissant les interactions moléculaires ou ioniques entre les solutés à séparer, la phase stationnaire et la phase mobile. Successeur du Manuel pratique de chromatographie en phase liquide, cet ouvrage s'adresse aux chimistes analystes de tous niveaux en respectant un équilibre entre les aspects théoriques et pratiques également indispensables à la réussite de séparations de qualité. Les scientifiques de toutes disciplines y trouveront aussi maints sujets de réflexion sur les interactions de nature et de niveaux énergétiques variés qui sont l'essence même de la chimie.

LA DISCUSSION DES AVANTAGES ET INCONVENIENTS DES DIVERSES METHODOLOGIES MONTRE QUE LE COUPLAGE AVEC L'EXTRACTION PAR FLUIDE SUPERCRITIQUE, SEMBLE LE PLUS PERFORMANT POUR INTRODUIRE L'ECHANTILLON EN TETE DE LA COLONNE DE SEPARATION. LES RESULTATS OBTENUS CONCERNANT L'ETUDE DE LA SURCHARGE DE LA COLONNE CHROMATOGRAPHIQUE EST GENERALEMENT DIFFERENT DE CELUI RENCONTRE EN CHROMATOGRAPHIE PREPARATIVE EN PHASE LIQUIDE (CPPL), PRINCIPALEMENT DU FAIT QUE LA DISTRIBUTION DES SOLUTES ENTRE LA PHASE STATIONNAIRE ET L'ELUANT SUPERCRITIQUE N'EST PAS REGIE PAR LA SATURATION DE LA PHASE STATIONNAIRE MAIS PAR LA SATURATION DE LA PHASE MOBILE.

This book was released on 2012-12-06 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of supercritical fluids in analytical chemistry is still grow ing. More and more analysts are discovering the favorable advan tages for a number of applications. Especially supercritical fluid extraction (SFE) has attracted a lot of interest in recent years due to its simplicity. Supercritical fluid chromatography (SFC) has become better established and the development of this technique has been accelerated by the many applications with capillary col umns which have been published in the literature. At first SFC equipment was based on instruments commonly used for liquid chromatography, and the first commercial in struments were derived from this technology. However, capillary columns can be much more easily interfaced to gas chromatogra phy equipment especially to the detectors commonly used for Oc. Many stationary phases both for packed micro columns and capillary columns have been designed for SFC purposes extending this technology to LC and OC. The most common fluid applied in SFC and SFE is carbon dioxide. The advantages of supercritical CO , such as having dif 2 fusivity like a gas and solvating power depending on temperature and pressure, are also valid for other fluids and modified fluids. Both properties are valuable for sample extraction and extraction selectivity.

Extrait: La chromatographie d'exclusion sterique (SEC d'apres l'anglais Size Exclusion Chromatography) ou chromatographie sur gel permeable (GPC d'apres l'anglais Gel Permeation Chromatography) ou encore Gel Filtration Chromatography (abrege GFC) est une methode de chromatographie en phase liquide permettant de separer des macromolecules en fonction de leur volume hydrodynamique. Elle est notamment utilisee pour evaluer la distribution des volumes hydrodynamiques dans un echantillon de polymeres. Schema simplifie du principe de la chromatographie d'exclusion sterique. Le chromatogramme represente la separation de 3 polymeres de tailles differentes en solution. Les molecules ayant le plus grand volume hydrodynamique (1) arrivent en tete, suivies des plus petites (2) puis (3).Contrairement aux methodes de chromatographie d'affinite (comme l'High Performance Liquid Chromatography), le principal phenomene physique permettant la separation des differentes macromolecules constituant le polymere n'est pas base sur l'affinite chimique avec le support, mais idealement sur la taille des macromolecules en solution (leur volume hydrodynamique). En realite, ces deux mecanismes de separation sont continuellement en competition au sein de la colonne; les conditions experimentales sont alors...

Download or read book Practical Application of Supercritical Fluid Chromatography for Pharmaceutical Research and Development written by and published by Elsevier. This book was released on 2022-12-02 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: Practical Application of Supercritical Fluid Chromatography for Pharmaceutical Research and Development provides a valuable "go-to reference for many difficult-to-solve challenges using pertinent chromatographic theory, first-hand case studies, and examples provided from academic and industry experts. This text also enables professors teaching an analytical instrumental course to introduce and instruct students about one of the most sustainable and powerful separation methods currently available. While the text has broad applicability across industrial sectors, it focuses primarily on application in the pharmaceutical industry. The book is designed to allow readers to align current HPLC/UHPLC capabilities with SFC as an orthogonal tool for project specific methods in the pharmaceutical industry. It highlights where SFC falls on the spectrum of useful chromatographic tools for routine and challenging separative methods. Experienced HPLC users who are interested in developing knowledge in orthogonal separation techniques, as well as newcomers to the field of separation science, will find this text particularly useful. Chapters address where SFC may fit the analytical needs of the pharmaceutical industry and alert the readers as to where the technique will not fit. Readers will gain an understanding of how and where SFC may be applied and adapted more routinely across the pharmaceutical industry as a 'green' way of undertaking separation opportunities and challenges. Areas within the pharmaceutical industry include early drug discovery, process chemistry, and late stage development and manufacturing. - Describes approaches to SFC column and mobile phase selection for method development for both analytical and preparative tasks - Gives practical examples of how analytical SFC enables the monitoring of synthetic reactions including unstable intermediates, chiral and achiral polar reactants and products across small and large modalities - Provides need-focused case studies for pharmaceutical analysts, process chemists, and contract chemistry facilities that can benefit from monitoring or purifying polar intermediates, mutagenic impurities, nitrosamines and other reaction by-products including excipients and metabolites
