Air pollution determination is one of the most important fields of gas chromatography application in practice. This book provides a systematic description of the main stages of air pollution determination, ranging from sampling problems to the quantitative estimation of the acquired data. Special attention is paid to the problem of gas, vapor, spray and solid particles extraction from air. The main methods of sampling procedure, namely, container utilization, cryogenic concentration, absorption, adsorption, chemisorption and filter usage, and successive impurities extraction are also handled. Sorption theory and the problems of sorption and desorption efficiency for hazardous impurities being extracted from traps with sorbents are discussed in detail. The practical utilization of different sorbents (silica, activated carbon, polymers etc.) to carry out sampling procedures for 200 main pollutants with known TLV (USSR and USA) is also considered. This highly informative book, reflecting several insufficiently known techniques as well as the experience of both western and Soviet researchers, should be of interest to both beginners and skilled researchers.

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.

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.

Genre | : Science |
ISBN | : 0080858392 |
This book gives a comprehensive, up-to-date review of all selective detectors used in combination with gas chromatography. For each detector, the historical background, design and principle are described, and the working parameters affecting the detector performance are analyzed critically and in detail. The analytical possibilities of the detectors and the main characteristics such as sensitivity, noise and minimum detectability are discussed. All the selective detectors that are currently used are discussed in detail. Combinations of GC with other techniques such as plasma emission spectroscopy, atomic absorption spectrometry, ion-selective electrodes, piezoelectric sorption detector, mass spectrometry and infrared spectroscopy are discussed briefly.Chromatographers and users of gas chromatographs, especially in the field of environmental protection, agriculture, clinical chemistry, and toxicology will find the book useful to their work. Institutes and organisations dealing with analytical chemistry will also find it of interest.

Bioaffinity chromatography is now the preferred choice for the purification, determination or removal of many biologically active substances. The book includes information on biologically active substances with their affinants, solid supports and methods of coupling, summarized in tables covering classical, high-performance liquid and large-scale bioaffinity chromatography.Optimization of the preparation and the use of highly active and stable biospecific adsorbents is discussed in several chapters. Following a chapter dealing with the choice of affinity ligands, affinity-sorbent bonding is described in detail. Other chapters give information on solid supports, the most common coupling procedures and a general discussion of sorption and elution. Several applications of bioaffinity chromatography are described, e.g. quantitative evaluation of biospecific complexes and many applications in medicine and in the biotechnology industry.
