The best source of practical, easily accessible information on thisexciting new technique CAPILLARY ELECTROPHORESIS Analytical chemists and biochemists have been turning to thetechnique of capillary electrophoresis with increasing frequency:it is fast, sensitive, easy to automate, requires only small samplevolumes and reagent amounts, and has been successfully applied toan ever-expanding list of sample types. In CapillaryElectrophoresis, analytical practitioners will find a complete,practical guide to the principles, forms, and instrumentation ofthis technique. The book presents clear and straightforwardexplanations of the method, its operating principles, and itsdifferent modes, including capillary zone electrophoresis, micellarelectrokinetic capillary chromatography, capillary gelelectrophoresis, capillary isoelectric focusing, and capillaryisotachophoresis. Especially helpful is the material on developinga method: it offers practical guidance on CE modes, capillaries,run buffers, voltage requirements, sample pretreatments, injectionmodes and amounts, temperature settings, detector selections,buffer replenishment, and data reporting. Capillary Electrophoresis will serve both as an excellentintroduction to those who are new to the technique and as acomprehensive reference book to experienced practitioners. Acomplete and detailed index will assist the reader in quicklyfinding any topic of interest.

A practical introduction to the applications, principles, design, and fabrication of biosensors, which are used to measure and analyze clinical medical problems, biotechnology processes, environmental impact, and living tissue. This accessible volume emphasizes accuracy of interpretation and maximizing information yield.

A reliable, comprehensive, relevant view of HPLC and its applications The development of HPLC-PED represents the successful marriage of two powerful analytical technologies and has resulted in the best technique for sensitive and direct detection of biological compounds with poor optical detection properties. PED has been used extensively for the determination of carbohydrates and other polar aliphatic compounds, and as a result, numerous methods have been developed to enable the analysis of a wide variety of samples. Over the years, many articles, anecdotal information, and misinformation have permeated the scientific community, with the possible consequence of confusion or uncertainty with regard to PED on the part of the analyst. Pulsed Electrochemical Detection in High-Performance Liquid Chromatography presents a reliable, comprehensive, and relevant review of HPLC-PED and its applications. The book is divided into three major parts: background material necessary for a more thorough understanding of the principles and relevance of PED; an in-depth discussion of PED using voltammetry and other electroanalytical techniques and presenting the advantages, applicability, and optimization of all existing PED waveforms; and practical aspects of HPLC-PED, including a summary of the major applications and a look at future developments in the technique. Appendices include a pulsed voltammetry (PV) program specifically written to optimize pulsed amperometric detection (PAD) waveforms and all the known applications, categorized and listed in tabular form. For analytical chemists; biochemists; carbohydrate chemists; biotechnologists; undergraduate, graduate, and postdoctoral students; and lab technicians working in a range of areas including the pharmaceutical, medical, and food and beverage industries, this eminently readable guide is the first reliable book-length treatment of how to use PED coupled with HPLC.

Clear, Practical Coverage of an Important Reemerging TechnologySupercritical Fluid Extraction provides a clear, practical, step-by-step introduction to a sample preparation method that helps laboratories reduce or eliminate the use of halogenated solvents, extract samples more quickly and efficiently, and improve the accuracy of their results. By encouraging a deliberate, systematic approach to supercritical fluid extraction (SFE) methods and techniques, this book enables scientists and technicians to avoid disappointing results and erroneous conclusions and develop reliable guidelines for using this versatile technology. It demonstrates how to make the most of a process that is highly reproducible, fast, and quantitative at sub-ppb levels; preserves the chemical integrity of the analyte to be extracted; and yields a concentrated sample solution that can be easily manipulated. Topics covered include: Properties of supercritical fluidsFunctional group solubility in supercritical fluidsCollection efficiency in off-line SFEExtraction strategiesApplications of analytical SFEFor analytical chemists, technicians, and laboratory managers, this book is the key to a technology that can make every sample extraction and analysis cleaner, more efficient, and more reliable.

A complete guide to choosing and using the best analytical technique for the job at hand Today's new generation of spectroscopic instrumentation allows for more accurate and varied measurements than ever before. At the same time, increasingly powerful, user-friendly PC hardware and software make running those instruments relative child's play. However, although they may have solved many of the problems traditionally associated with conducting molecular spectroscopic analyses, these refinements tend to obscure inherent technical challenges which, if not taken into consideration, can seriously undermine a research initiative. Modern Techniques in Applied Molecular Spectroscopy gives scientists and technicians the knowledge they need to address those challenges and to make optimal selection and use of contemporary molecular spectroscopic techniques and technologies. While editor Francis Mirabella and contributors provide ample background information about how and why individual techniques work, they concentrate on practical considerations of crucial concern to researchers working in industry. For each technique covered, they provide expert guidance on method selection, sample preparation, troubleshooting, data handling and analysis, and more. Adhering principally to mid-IR molecular spectroscopic techniques, they clearly describe the guiding principles behind, characteristics of, and suitable applications for transmission spectroscopy, reflectance spectroscopies, photoacoustic spectroscopy, infrared and Raman microspectroscopy, fiber optic techniques, and emission spectroscopy. Modern Techniques in Applied Molecular Spectroscopy is an indispensable working resource for analytical scientists and technicians working in an array of industries.
