Book Synopsis Applications of LC-MS in Environmental Chemistry by : Damia Barcelo
Download or read book Applications of LC-MS in Environmental Chemistry written by Damia Barcelo and published by Elsevier. This book was released on 1996-03-21 with total page 567 pages. Available in PDF, EPUB and Kindle. Book excerpt: Looking at the literature available, it is clear that there is a need for a book on LC-MS applications in environmental analysis. This book endeavours to answer the following questions: What interface to use to solve "my detection problem"? Can I obtain enough sensitivity for the confirmation of my compound in real-world environmental samples? Is there enough structural information?The present book aims to provide a critical evaluation of LC-MS in environmental chemistry and it is structured in different areas. Apart from an introductory section with fundamental aspects, application areas using the most relevant interfacing systems (PB, TSP, ES) for the characterization of environmental compounds are included. In this sense, applications are discussed on the characterization of the most relevant compounds of environmental interest such as pesticides, detergents, dyes, polar metabolites, waste streams, organotin compounds and marine toxins with comparison between different interfacing systems. Finally, new methods and strategies in LC-MS, e.g. the use of capillary electrophoresis, MS together with on-line post-column systems in LC-MS are also shown.By the nature of its content and written as it is by experienced practitioners, the book is intended to serve as a practical reference for analytical chemists who need to use LC-MS in environmental studies. Each chapter includes sufficient references to the literature to serve as a valuable starting point and also contains detailed investigations. The broad spectrum of the book and its application to environmental priority compounds makes it unique in many ways.

Book Synopsis Polymer Characterization by Liquid Chromatography by : G. Glöckner
Download or read book Polymer Characterization by Liquid Chromatography written by G. Glöckner and published by Elsevier. This book was released on 1987-02-01 with total page 589 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main subject of this book is the characterization of plastics. To a high degree the properties of these polymers depend on the distribution of the molar mass and of other structural features, and small deviations frequently have a great effect. Therefore the characterization of polymers cannot be restricted to the determination of mean values but must yield information on these distributions. Using classical methods, the analytical fractionation of polymer homologues and structurally isomeric polymers is extremely time-consuming. Therefore, efficient chromatographic techniques are being increasingly employed in modern polymer characterization.In the first place, high-performance liquid chromatography is applied, in the form of size exclusion chromatography. It is also possible, however, to use other separation modes. More space is devoted to these other possibilities in this volume than is merited by their current range of applications, as the author believes that many separation problems will be solved by separation techniques of the non-exclusion type. Nevertheless, much emphasis is placed on size exclusion chromatography. Not only because of its current wide range of applications, but also because its relative importance, as a complement to other chromatographic techniques may even increase in the forthcoming years.This book is the first to cover all phenomena related to the above considerations. Starting with an introduction to basic liquid chromatography and to polymer science, it deals with the adsorption behaviour of polymers, with gradient techniques, with the kinetic band broadening in liquid chromatography, with instrumental features and packing materials. The book consists of four balanced sections and related information from about 1800 references is compiled in the tables. Some 250 figures and 30 tables will help give the reader a clear insight of the topics discussed. The book is aimed at helping the analyst or polymer chemist who is looking for information about chromatographic methods for the characterization of polymers.
Book Synopsis Preparative Liquid Chromatography by : B.A. Bidlingmeyer
Download or read book Preparative Liquid Chromatography written by B.A. Bidlingmeyer and published by Elsevier. This book was released on 1987-07-01 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume provides a straightforward approach to isolation and purification problems with a thorough presentation of preparative LC strategy including the interrelationship between the input and output of the instrumentation, while keeping to an application focus.The book stresses the practical aspects of preparative scale separations from TLC isolations through various laboratory scale column separations to very large scale production. It also gives a thorough description of the performance parameters (e.g. throughput, separation quality, etc.) as a function of operational parameters (e.g. particle size, column size, solvent usage, etc.). Experts in the field have contributed a well balanced presentation of separation development strategies from preparative TLC to commercial preparative process with practical examples in a wide variety of application areas such as drugs, proteins, nucleotides, industrial extracts, organic chemicals, enantiomers, polymers, etc.
Book Synopsis Protein Liquid Chromatography by : M. Kastner
Download or read book Protein Liquid Chromatography written by M. Kastner and published by Elsevier. This book was released on 2000 with total page 978 pages. Available in PDF, EPUB and Kindle. Book excerpt: Protein Liquid Chromatography is a handbook-style guide to liquid chromatography as a tool for isolating and purifying proteins, consisting of 25 individual chapters divided into three parts: Part A covers commonly-used, classic modes of chromatography such as ion-exchange, size-exclusion, and reversed-phase; Part B deals with various target protein classes such as membrane proteins, recombinant proteins, and glycoproteins; and Part C looks at various miscellaneous related topics, including coupling reaction, buffer solution additives, and software. The text as a whole can be viewed as a systematic survey of available methods and how best to use them, but also attempts to provide an exhaustive coverage of each facet. How to solve a specific problem using a chosen method is the overall essence of the volume. The principle philosophy of this compilation is that practical application is everything; therefore, both classical and modern methods are presented in detail, with examples involving conventional, medium- and high-pressure techniques. Over-exposure to history, concept, and theory has deliberately been avoided. The reader will find a wealth of tips and tricks from users for users, including advice on the advantages and disadvantages of each method. Easy-to-read sections on "Getting started now" and "Where to go from here" attempt to provide hands-on, fool-proof detailed practical procedures with complete and even standard model runs for any scientist or technician at work in this area.

Book Synopsis Retention and Selectivity in Liquid Chromatography by : R.M. Smith
Download or read book Retention and Selectivity in Liquid Chromatography written by R.M. Smith and published by Elsevier. This book was released on 1995-01-13 with total page 479 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book brings together a number of studies which examine the ways in which the retention and selectivity of separations in high-performance liquid chromatography are dependent on the chemical structure of the analytes and the properties of the stationary and mobile phases. Although previous authors have described the optimisation of separations by alteration of the mobile phase, little emphasis has previously been reported of the influence of the structure and properties of the analyte.The initial chapters describe methods based on retention index group increments and log P increments for the prediction of the retention of analytes and the ways in which these factors are influenced by mobile phases and intramolecular interactions. The values of a wide range of group increments in different eluents are tabulated.Different scales of retention indices in liquid chromatography are described for the comparison of separations, the identification of analytes and the comparison of stationary phases. Applications of these methods in the pharmaceutical, toxicology, forensic, metabolism, environmental, food and other fields are reviewed. The effects of different mobile phases on the selectivity of the retention indices are reported. A compilation of sources of reported retention index values are given.Methods for the comparison of stationary phases based on the interactions of different analytes are covered, including lipophilic and polar indices, shape selectivity comparisons, their application to novel stationary phases, and chemometric methods for column comparisons.

Book Synopsis Selective Sample Handling and Detection in High-Performance Liquid Chromatography by : K. Zech
Download or read book Selective Sample Handling and Detection in High-Performance Liquid Chromatography written by K. Zech and published by Elsevier. This book was released on 1989-10-30 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the second of a two-volume project which treats the handling, separation and detection of complex samples as an integrated, interconnected process. On the basis of this philosophy the editors have selected those contributions which demonstrate that optimal sample preparation leads to a simplification of detection or reduced demands on the separation process. Throughout the book emphasis is on chemical principles with minimum discussion of the equipment required - an approach which reflects the editors' view that the limiting factor in the analysis of complex samples is an incomplete knowledge of the underlying chemistry rather than the hardware available. This lack of knowledge becomes more evident as the demands for lower detection limits grow, as solving complex matrix problems requires a greater understanding of the chemical interaction between the substance to be analysed and the stationary phase. Thus, apart from one chapter dealing with chemically modified silicas, the main theme of the book is developed in three chapters on sample preparation and three on detection.The opening chapter outlines concentration and chromatography on chemically modified silicas with complexing properties, and gives examples of the use of these phases with organic and inorganic compounds. Chapter II, the first of the three contributions dealing with sample preparation, addresses such questions as whether the prepared sample is representative of the material to be analysed; how to avoid contamination; which separation procedure should be used to avoid tedious sample preparation. Chapter III describes the processing of whole blood for drug analysis. The determination of cyclosporine and its metabolites (an especially difficult case) demonstrates how comprehensive the optimisation of sample preparation must be to successfully perform the analysis. Several other examples are also given. Chapter IV deals with radio-column liquid chromatography and introduces the other theme of the book, i.e. selective detection methods. The widespread use of radioisotopes requires a high degree of purification during the manufacture of the compounds, as well as highly accurate detection methods in biological and biochemical studies.Chapter V continues the theme of selective detection with an overview of post-column reaction detection. The use of immobilised enzymes in post-column reactors or `pumpless' reactor systems for on-line reagent generation after the chromatographic separation step is discussed in detail. Various examples of the separation of biological compounds show how the production of electrochemical reagents and photochemical reaction detection have increased the selectivity of the detection, leading to more economical analytical systems. Selective detection employing luminescence detection techniques is outlined in Chapter VI. The use of immobilised fluorophores or the coupling to photochemical reactions leads to highly selective detection systems which can greatly simplify the sample handling. The final chapter reviews the use of continuous separation techniques in flow injection analysis thus revealing the need for a strong interdisciplinary dependence between sample handling and separation in this area.Written by experienced practitioners, this book will be extremely useful to investigators in many areas of application. Each chapter includes sufficient references to the literature to serve as a valuable starting point for more detailed investigation. The strong emphasis on sample handling makes the book unique in many ways and it will be welcomed by environmental scientists as well as those active in the clinical, pharmaceutical and bioanalytical fields.
