Forced-Flow Layer Chromatography takes a close look at the specifics of forced-flow layer chromatography techniques, from their evolution to the nuances of using these techniques in a variety of applications where traditional thin-layer chromatography (TLC) and high-performance thin-layer chromatography (HPTLC) are not as effective. This book presents a number of variations of TLC techniques, with special emphasis on the overpressured-layer chromatography (OPLC) technique and newer developments such as the BioArena System for biomedical analysis. The versatility of these forced-flow techniques opens up new avenues for the analysis of a large number of samples for high-throughput screening and for the analysis of very complex matrices, while the development of BioArena extends the use of these techniques to challenging new areas of bioanalysis. Details a variety of forced-flow techniques, explaining how they markedly reduce developing time and result in less lateral diffusion and more compact spots Emphasizes the benefits of OPLC separation techniques, a method pioneered by the authors nearly forty years ago Discusses new developments, such as the BioArena system used to facilitate detection, isolation, and identification of new antimicrobials, antineoplastics, biopesticides, and other biologically active substances

A comprehensive, practical approach to three powerful methods of polymer analysis and characterization This book serves as a complete compendium of three important methods widely used for the characterization of synthetic and natural polymers—light scattering, size exclusion chromatography (SEC), and asymmetric flow field flow fractionation (A4F). Featuring numerous up-to-date examples of experimental results obtained by light scattering, SEC, and A4F measurements, Light Scattering, Size Exclusion Chromatography and Asymmetric Flow Field Flow Fractionation takes an all-in-one approach to deliver a complete and thorough explanation of the principles, theories, and instrumentation needed to characterize polymers from the viewpoint of their molar mass distribution, size, branching, and aggregation. This comprehensive resource: Is the only book gathering light scattering, size exclusion chromatography, and asymmetric flow field flow fractionation into a single text Systematically compares results of size exclusion chromatography with results of asymmetric flow field flow fractionation, and how these two methods complement each other Provides in-depth guidelines for reproducible and correct determination of molar mass and molecular size of polymers using SEC or A4F coupled with a multi-angle light scattering detector Offers a detailed overview of the methodology, detection, and characterization of polymer branching Light Scattering, Size Exclusion Chromatography and Asymmetric Flow Field Flow Fractionation should be of great interest to all those engaged in the polymer analysis and characterization in industrial and university research, as well as in manufacturing quality control laboratories. Both beginners and experienced can confidently rely on this volume to confirm their own understanding or to help interpret their results.

On-site determination of nitroaromatic, nitramine, and nitrate ester explosives compounds in soils was performed using a field-portable gas chromatograph (GC)equipped with a thermionic ionization detector (TID)selective for compounds with nitro functional groups. Soil samples were extracted with acetone. A 1 microliter volume of the filtered soil extract was manually injected into the GC, allowing for the rapid qualification and quantification of the suite of explosives that often coexist in soils at military training facilities and other defense-related sites. Good agreement was established for the concentrations of several explosives analytes when this method of analysis was compared to either high-performance liquid chromatography (Method 8330)or GC electron capture (Method 8095)analysis. Comparisons were performed for sample extracts and for soil subsample replicates distributed for on-site preparation and analysis during a field verification test performed under the auspices of the U.S. Environmental Protection Agency's Environmental Technology Verification (ETV)Program.

Chromatography and all the related separation techniques are experimental in their origin and justification. However, the spectacular progress made in this area since World War II has given rise to a theoretical underpinning. The present book covers the current status of the research area and places it in perspective with the general concepts of the fields of physical chemistry involved. The ASI lectures/authors -- well known leaders in their fields -- have written presentations at the graduate level, accessible to all those who have a good general background in the thermodynamics and mass transfer theory of phase equilibria. The book will be useful to young scientists and engineers who wish to access the current frontiers in chromatography and other separation sciences.

Guiding chromatographers working in regulated industries and helping them to validate their chromatography data systems to meet data integrity, business and regulatory needs. This book is a detailed look at the life cycle and documented evidence required to ensure a system is fit for purpose throughout the lifecycle. Initially providing the regulatory, data integrity and system life cycle requirements for computerised system validation, the book then develops into a guide on planning, specifying, managing risk, configuring and testing a chromatography data system before release. This is followed by operational aspects such as training, integration and IT support and finally retirement. All areas are discussed in detail with case studies and practical examples provided as appropriate. The book has been carefully written and is right up to date including recently released FDA data integrity guidance. It provides detailed guidance on good practice and expands on the first edition making it an invaluable addition to a chromatographer’s book shelf.

Leading researchers discuss the past and present of chromatography More than one hundred years after Mikhail Tswett pioneered adsorption chromatography, his separation technique has developed into an important branch of scientific study. Providing a full portrait of the discipline, Chromatography: A Science of Discovery bridges the gap between early, twentieth-century chromatography and the cutting edge of today’s research. Featuring contributions from more than fifty award-winning chromatographers, Chromatography offers a multifaceted look at the development and maturation of this field into its current state, as well as its importance across various scientific endeavors. The coverage includes: Consideration of chromatography as a unified science rather than just a separation method Key breakthroughs, revolutions, and paradigm shifts in chromatography Profiles of Nobel laureates who used chromatography in their research, and the role it played Recent advances in column technology Chromatography’s contributions to the agricultural, space, biological/medical sciences; pharmaceutical science; and environmental, natural products, and chemical analysis Future trends in chromatography With numerous references and an engaging series of voices, Chromatography: A Science of Discovery offers a diverse look at an essential area of science. It is a unique and invaluable resource for researchers, students, and other interested readers who seek a broader understanding of this field.
