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.

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.

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.

It is now some sixteen years since the author's first series of books on the analysis of organometallic compounds. Many developments in the subject have occurred since that time and a new book on the subject is now overdue. The present book aims to provide a comprehensive review of the subject. It covers not only all aspects of the analysis of organometallic compounds but also contains two additional chapters, dealing with environmental analysis and the use of chelates of metals in the determination of very low concentrations of organic metals. Whilst reviewing the literature for the present book, it was observed that whereas papers published prior to 1973 dealt almost exclusively with various forms of analysis, a high proportion of those published during the past ten years were concerned with the application of proven or newly developed methods to the determination of organometallic compounds in environmental samples such as water, air, soil, river and ocean sediments, fish life and biota samples. An increasing range of elements including mercury, lead, arsenic, tin, antimony, selenium and manganese are now being found in organically bound forms in the environment, some resulting from pollution, others formed in nature by bacterial processes. As many of these substances have appreciable implications to human and animal health and the ecosystem as a whole, it was considered that it would be timely to include a separate chapter in the book devoted entirely to this subject.
