Description

The latest edition of the authoritative reference to HPLCHigh-performance liquid chromatography (HPLC) is today the leading technique for chemical analysis and related applications, with an ability to separate, analyze, and/or purify virtually any sample. Snyder and Kirkland's Introduction to Modern Liquid Chromatography has long represented the premier reference to HPLC. This Third Edition, with John Dolan as added coauthor, addresses important improvements in columns and equipment, as well as major advances in our understanding of HPLC separation, our ability to solve problems that were troublesome in the past, and the application of HPLC for new kinds of samples.This carefully considered Third Edition maintains the strengths of the previous edition while significantly modifying its organization in light of recent research and experience. The text begins by introducing the reader to HPLC, its use in relation to other modern separation techniques, and its history, then leads into such specific topics as:The basis of HPLC separation and the general effects of different experimental conditionsEquipment and detectionThe column—the "heart" of the HPLC systemReversed-phase separation, normal-phase chromatography, gradient elution, two-dimensional separation, and other techniquesComputer simulation, qualitative and quantitative analysis, and method validation and quality controlThe separation of large molecules, including both biological and synthetic polymersChiral separations, preparative separations, and sample preparationSystematic development of HPLC separations—new to this editionTroubleshooting tricks, techniques, and case studies for both equipment and chromatogramsDesigned to fulfill the needs of the full range of HPLC users, from novices to experts, Introduction to Modern Liquid Chromatography, Third Edition offers the most up-to-date, comprehensive, and accessible survey of HPLC methods and applications available.

Description

An in-depth guide to HPLC column technology High-performance liquid chromatography and its derivative techniques have become the dominant analytical separation tools in the pharmaceutical, chemical, and food industries; environmental laboratories; and therapeutic drug monitoring. Although the column is the heart of the HPLC instrument and essential to its success, until now, no book has focused on the theory and practice of column technology. HPLC Columns provides thorough, state-of-the-art coverage of HPLC column technology for the practicing technician and academician alike. Along with a comprehensive discussion of the chemical and physical processes of the HPLC column, it includes fundamental principles, separation mechanisms and available technologies, column selection criteria, and special techniques. Special features include:* Comprehensive overview of state-of-the-art HPLC column technology* Explanation of the underlying principles of HPLC columns* Methods for selecting columns* Practical advice on using and applying columns, including examples* Section by M. Zoubair El Fallah on methods development* Special techniques, including preparative chromatography, continuous chromatography, and the simulated moving bed* Troubleshooting sectionHPLC Columns helps laboratory practitioners make better choices in column selection, methods development, and troubleshooting: it is also an excellent textbook for graduate-level courses and HPLC short courses.
