This book was released on 1987-12-01 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the first of a two-volume project which attempts to treat the sample handling and detection processes in a liquid chromatographic system in an integrated fashion. The need for more selective and sensitive chromatographic methods to help solve the numerous trace analysis problems in complex samples is undisputed. However, few workers realize the strong interdependence of the various steps - sample handling, separation and detection - which must be considered if one wants to arrive at an optimal solution. By introducing a strong element of selectivity and trace enrichment in the sample preparation step, fewer demands are placed on the quality of the chromatography and often a simple UV detector can be used. By using a selective detection mode, i.e. a reaction detector, the sample handling step can frequently be simplified and more easily automated. The impact of such a ``total system'' approach on handling series of highly complex samples such as environmental specimens or biological fluids can be easily imagined. Each chapter includes sufficient references to the literature to serve as a valuable starting point for more detailed investigation. Special emphasis is placed on the sample handling, and high priority has been given to the treatment of chemical principles applied to the topics presented, rather than to instrumentation. Written by experienced practitioners, this volume will be of interest to investigators in many areas of application, including environmental scientists and those active in the clinical, pharmaceutical and bioanalytical fields.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Handbook of Chromatography features tables and chromatograms, theoretical discussions, and practical applications on the topic. Tables and chromatograms are based on polymer analyses abstracted from literature references dating from 1981-1991. Compounds presented in the tables and chromatograms include residual monomers, plasticizers, additives, antioxidants, and products from the thermal degradation (pyrolysis) of a broad range of synthetic polymers. Theoretical discussions focus on new developments in the respective areas of gas, pyrolysis-gas, liquid, and size exclusion chromatographic separations. Capillary column technology, inverse gas chromatography (IGC), supercritical fluid extractions (SFE), and supercritical fluid chromatography (SFC) are also covered. A Practical Applications subsection provides a list of commercial suppliers of column packings and packed columns for gas and liquid chromatography. The book will be an excellent reference for chromatographers, organic chemists, and analytical chemists.

Available in PDF, EPUB and Kindle. Book excerpt: During recent years both research activity and the number of reports on biosensor systems applied to environmental analysis have increased significantly. Compounds present in the environment have increasingly been shown to have effects on biological systems such as cells, enzymes, binding proteins, and DNA. In order to deal with the increasing demand for information about possible pollution of the environment there is need for improvements to analytical methods. Thus, biochemistry-based analytical methods should offer the possibility of monitoring these effects. This text provides an overview of existing biosensor principles, commercially available instruments, and related biochemical assays which have been developed and applied to environmental monitoring. Providing the reader with detailed information on methodology and a description of the practical application of selected sensors, this text also includes reports on established chemical methods for comparison. This volume presents fundamental principles together with examples of applications and discussion of drawbacks, and future developments. Of interest to all in the field of environmental analysis and biosensor technology, this text provides a comprehensive treatise on the latest research and developments in the field.
