This book was released on 2010-06-03 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: High-temperature liquid chromatography has attracted much interest in recent years but has not yet recognized its full potential in the chromatographic community. There is a widespread reluctance in industry to use temperature to speed up the separation process, influence the selectivity of a separation or implement novel detection techniques. However, the technology has now matured and could revolutionize chromatography as we see it today. Better equipment, such as heating systems able to generate faster heating rates, is becoming more readily available. Also, columns based on silica gel, which can withstand higher temperatures for an extended period, are now being introduced. Nevertheless, further technological and methodical efforts are needed to establish the method in a regulated environment like the pharmaceutical industry. This is the only text to cover all the practical aspects, as well as the underlying theoretical principles, of setting up an HPLC system for high temperature operation. It is not intended solely for academics but will also benefit the researcher interested in more practical considerations. The author is a recognized expert and has conducted several studies with partners from industry to validate the method. Many real examples from these studies have been included in the book. The aim is to support practitioners in the creation of their own protocols without the need to rely solely on trial and error. The book starts with a brief definition of high temperature liquid chromatography before going on to cover: system set up; the heating system; mobile phase considerations; suitable stationary phases; method development using temperature programming; analyte stability, and special hyphenation techniques using superheated water as a mobile phase. In each chapter, experimental data is used to illustrate the main statements and the advantages over conventional HPLC are evaluated. The book concludes with a critical outlook on further developments and applications underlining the necessary advances needed to make high temperature HPLC more robust.

Download or read book Fast Liquid Chromatography–Mass Spectrometry Methods in Food and Environmental Analysis written by Oscar Núñez and published by World Scientific. This book was released on 2015-02-13 with total page 624 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a growing need for high-throughput separations in food and environmental research that are able to cope with the analysis of a large number of compounds in very complex matrices. Whereas the most common approach for solving many analytical problems has often been high-performance liquid chromatography (HPLC), the recent use of fast or ultra-fast chromatographic methods for environmental and food analysis has increased the overall sample throughput and laboratory efficiency without loss (and even with an improvement) in the resolution obtained by conventional HPLC systems. This book brings together researchers at the top of their field from across the world to discuss and analyze recent advances in fast liquid chromatography–mass spectrometry (LC–MS) methods in food and environmental analysis. First, the most novel approaches to achieve fast and ultra-fast methods as well as the use of alternative and complementary stationary phases are described. Then, recent advances in fast LC–MS methods are addressed, focusing on novel treatment procedures coupled with LC–MS, new ionization sources, high-resolution mass spectrometry, and the problematic confirmation and quantification aspects in mass spectrometry. Finally, relevant LC–MS applications in food and environmental analysis such as the analysis of pesticides, mycotoxins, food packaging contaminants, perfluorinated compounds and polyphenolic compounds are described. The scope of the book is intentionally broad and is aimed at worldwide analytical laboratories working in food and environmental applications as well as researchers in universities worldwide.

This book was released on 2012-12-06 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the first edition of this book the major advances have been in column packings, where over ninety per cent of separations are now performed using chemically bonded microparticulate packings, and in instrumentation. The use of microprocessor control has brought about a rationalization of mobile phase delivery systems and in detectors, the introduction of electrochemical and spectrophotometric detection other than in the ultra-violet region, has widened the field of applications and the sensitivity of the technique. The use of ion pair chromatography has increased at the expense of ion-exchange and this together with the improvements in detectors has greatly increased the appli cation of the technique in the biomedical field. These advances are described together with the established methods to enable the beginner to carry out a satisfactory separation and to gain the experience necessary for the full exploitation of the technique. R. J. Hamilton P. A. Sewell Liverpool,1981 1 Introduction to high performance liquid chromatography 1. 1 Introduction Chromatography in its many forms is widely used as a separative and an analytical technique. Gas chromatography since its introduction by James and Martin [1] has been pre-eminent in the field. Uquid chromatography in the of paper, thin-layer, ion-exchange, and exclusion (gel permeation and gel form filtration) chromatography had not been able to achieve the same success, mainly because of the poor efficiences and the long analysis times arising from the low mobile phase flow rates.

Download or read book Monitoring Polymerization Reactions written by Wayne F. Reed and published by John Wiley & Sons. This book was released on 2014-01-21 with total page 493 pages. Available in PDF, EPUB and Kindle. Book excerpt: Offers new strategies to optimize polymer reactions With contributions from leading macromolecular scientists and engineers, this book provides a practical guide to polymerization monitoring. It enables laboratory researchers to optimize polymer reactions by providing them with a better understanding of the underlying reaction kinetics and mechanisms. Moreover, it opens the door to improved industrial-scale reactions, including enhanced product quality and reduced harmful emissions. Monitoring Polymerization Reactions begins with a review of the basic elements of polymer reactions and their kinetics, including an overview of stimuli-responsive polymers. Next, it explains why certain polymer and reaction characteristics need to be monitored. The book then explores a variety of practical topics, including: Principles and applications of important polymer characterization tools, such as light scattering, gel permeation chromatography, calorimetry, rheology, and spectroscopy Automatic continuous online monitoring of polymerization (ACOMP) reactions, a flexible platform that enables characterization tools to be employed simultaneously during reactions in order to obtain a complete record of multiple reaction features Modeling of polymerization reactions and numerical approaches Applications that optimize the manufacture of industrially important polymers Throughout the book, the authors provide step-by-step strategies for implementation. In addition, ample use of case studies helps readers understand the benefits of various monitoring strategies and approaches, enabling them to choose the best one to match their needs. As new stimuli-responsive and "intelligent" polymers continue to be developed, the ability to monitor reactions will become increasingly important. With this book as their guide, polymer scientists and engineers can take full advantage of the latest monitoring strategies to optimize reactions in both the lab and the manufacturing plant.
