Selection of the HPLC Method in Chemical Analysis


Book Description

Selection of the HPLC Method in Chemical Analysis serves as a practical guide to users of high-performance liquid chromatography and provides criteria for method selection, development, and validation. High-performance liquid chromatography (HPLC) is the most common analytical technique currently practiced in chemistry. However, the process of finding the appropriate information for a particular analytical project requires significant effort and pre-existent knowledge in the field. Further, sorting through the wealth of published data and literature takes both time and effort away from the critical aspects of HPLC method selection. For the first time, a systematic approach for sorting through the available information and reviewing critically the up-to-date progress in HPLC for selecting a specific analysis is available in a single book. Selection of the HPLC Method in Chemical Analysis is an inclusive go-to reference for HPLC method selection, development, and validation. - Addresses the various aspects of practice and instrumentation needed to obtain reliable HPLC analysis results - Leads researchers to the best choice of an HPLC method from the overabundance of information existent in the field - Provides criteria for HPLC method selection, development, and validation - Authored by world-renowned HPLC experts who have more than 60 years of combined experience in the field




Separation Technologies for the Industries of the Future


Book Description

Separation processes—or processes that use physical, chemical, or electrical forces to isolate or concentrate selected constituents of a mixture—are essential to the chemical, petroleum refining, and materials processing industries. In this volume, an expert panel reviews the separation process needs of seven industries and identifies technologies that hold promise for meeting these needs, as well as key technologies that could enable separations. In addition, the book recommends criteria for the selection of separations research projects for the Department of Energy's Office of Industrial Technology.







Separation Techniques in Clinical Chemistry


Book Description

This reference examines innovations in separation science for improved sensitivity and cost-efficiency, increased speed, higher sample throughput and lower solvent consumption in the assessment, evaluation, and validation of emerging drug compounds. It investigates breakthroughs in sample pretreatment, HPLC, mass spectrometry, capillary electrophor




Quantitative Chemical Analysis


Book Description

This book covers both fundamental and practical aspects of chemical analysis: Data Process and Analysis; Chemical Equilibria and Volumetric titrations; Gravimetry; Spectrophotometry; Sample Preparation and Separation Methods in Quantitative Analysis. It was written with the rich tradition of teaching at Peking University College of Chemistry, and edited by an American professor who was personally sensitive to the needs of students learning science from traditional chemistry textbooks written in English. Many examples and illustrative problems in this text have been taken from previous textbooks by the Peking University Team Teaching Program. The book can be used as a starter in analytical chemistry which is fundamental and the base upon which chemistry is built. Traditional chapters of initial learning in analytical chemistry are included, such as volumetric, gravimetric and separation methods; the book also includes key chapters on problem solving relating to recent progress in analytical chemistry.




Separation Process Essentials


Book Description

Separation Process Essentials provides an interactive approach for students to learn the main separation processes (distillation, absorption, stripping, and solvent extraction) using material and energy balances with equilibrium relationships, while referring readers to other more complete works when needed. Membrane separations are included as an example of non-equilibrium processes. This book reviews and builds on material learned in the first chemical engineering courses such as Material and Energy Balances and Thermodynamics as applied to separations. It relies heavily on example problems, including completely worked and explained problems followed by "Try This At Home" guided examples. Most examples have accompanying downloadable Excel spreadsheet simulations. The book also offers a complementary website, http://separationsbook.com, with supplementary material such as links to YouTube tutorials, practice problems, and the Excel simulations. This book is aimed at second and third year undergraduate students in Chemical engineering, as well as professionals in the field of Chemical engineering, and can be used for a one semester course in separation processes and unit operations.




A Research Agenda for Transforming Separation Science


Book Description

Separation science plays a critical role in maintaining our standard of living and quality of life. Many industrial processes and general necessities such as chemicals, medicines, clean water, safe food, and energy sources rely on chemical separations. However, the process of chemical separations is often overlooked during product development and this has led to inefficiency, unnecessary waste, and lack of consensus among chemists and engineers. A reevaluation of system design, establishment of standards, and an increased focus on the advancement of separation science are imperative in supporting increased efficiency, continued U.S. manufacturing competitiveness, and public welfare. A Research Agenda for Transforming Separation Science explores developments in the industry since the 1987 National Academies report, Separation and Purification: Critical Needs and Opportunities. Many needs stated in the original report remain today, in addition to a variety of new challenges due to improved detection limits, advances in medicine, and a recent emphasis on sustainability and environmental stewardship. This report examines emerging chemical separation technologies, relevant developments in intersecting disciplines, and gaps in existing research, and provides recommendations for the application of improved separation science technologies and processes. This research serves as a foundation for transforming separation science, which could reduce global energy use, improve human and environmental health, and advance more efficient practices in various industries.
