Book excerpt: Post-column photochemical reactions may be used to enhance the sensitivity or selectivity of detection in high-performance liquid chromatography (HPLC). Several new photochemical reaction detection schemes are discussed. Anthraquinones may be detected with extremely high selectivity based on a photocatalytic reaction in the presence of oxygen to produce hydrogen peroxide. The hydrogen peroxide is subsequently detected by the highly sensitive peroxyoxalate chemiluminescence reaction. Catalytic factors ranging from 40 to 70 are achieved for many quinone analytes. Use of an immobilized fluorophore and solid-bed reagent addition makes this detection scheme particularly easy to implement. In the absence of oxygen, quinones are photoreduced in the presence of certain hydrogen-atom-donating substrates to produce highly fluorescent dihydroquinones. Thus, quinone derivatives may be used as photochemical reagents for the detection of analytes such as aliphatic alcohols, ethers, aldehydes, and amines. This post-column photochemical reaction is particularly useful for the detection of compounds having no chromophore such as saccharides and steroids. The fast reaction of singlet oxygen with either 2,5-diphenylfuran or 2,5-dimethylfuran forms the basis of a photochemical amplifier for UV-absorbing compounds. This method is photocatalytic and leads to improved detection limits in UV absorption by factors of one to two orders of magnitude. This photochemical reaction allows non-fluorescent compounds to be detected in HPLC using a UV detector with sensitivities rivaling those of fluorescence detection (typically 1 to 10 pg of compound).

This book was released on 2007-01-30 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book aims to fill the gap that exists between theoretical treatments of chromatography, and clinical chemistry and toxicology texts, which focus almost exclusively on clinical relevance and applications. Chromatography has a vast array of clinical applications, and though the chromatographic methods were first introduced decades ago, new applications of this technology are being used to explore previously inaccessible frontiers in clinical diagnostics and toxicological testing. An up-to-date book devoted to clinical and toxicological applications of chromatographic methods will serve as an instructional and reference text, useful to students, laboratory technicians, and researchers.

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.

Download or read book The Essence of Chromatography written by Colin F. Poole and published by Elsevier. This book was released on 2002-12-05 with total page 940 pages. Available in PDF, EPUB and Kindle. Book excerpt: The knowledge base of chromatography continued to expand throughout the 1990s owing to its many applications to problems of contemporary interest in industry, life and environmental sciences. Organizing this information into a single text for a diverse group of scientists has become increasingly difficult. The present book stemmed from the desire to revise Chromatography Today, written by the same author with Salwa K. Poole, and published in 1991. This title is considered to be one of the definitive texts on chromatography. It was soon realized however, that a simple revision would not provide the desired result of a contemporary picture of the practice of chromatography at the turn of the century. The only workable solution was to start afresh, maintaining the same general philosophy and concept for Chromatography Today where possible, while creating essentially a new book. The format of the new book is modular, with extensive cross-references to permit rapid location of related material using different separation concepts. Important features are extensive tabulation of essential data for performing separations and an extensive bibliography to the most recent literature. This title is intended as a suitable text for graduate level courses in the separation sciences and as a self-study guide for professional chromatographers wishing to refresh their background in this rapidly expanding field. The Essence of Chromatography presents a comprehensive survey of modern chromatography and is an effective replacement for Chromatography Today. · Comprehensive and authoritative coverage of chromatographic techniques · Contains extensive coverage of recent literature on this subject · Ideal text for graduates and suitable for professional chromatographers
