Written for all those who use chromatography as an analytical tool, this book covers all areas of gas, liquid, and thin-layer chromatography; no other book offers the same scope. The authors have had considerable experience in teaching graduate-level courses and the material presented here has been tried and tested, having formed the basis for short courses taught to groups of industrial chemists. Emphasis is on the practice of chromatographic methods, including ``how to'' sections and numerous examples of calculation methods. Extensively illustrated, the book contains numerous tables of all useful constants, materials and formulas frequently used by chromatographers. Valuable features are the chapters on sample preparation for chromatographic analysis, on instrumental methods for sample identification, and the comprehensive literature review.
This volume details the principles and instrumentation of gas chromatography-mass spectrometry (CG-MS), and outlines industrial, environmental, pharmaceutical, clinical, toxicological, forensic and food-related applications, revealing findings from the laboratories of 40 contributing scientists around the world using GC-MS in practice. It describes upstream and downstream applications of GC-MS in the petroleum industry and identifies chlorinated compounds in the environment with quadrupole ion-trap technology and high-resolution sector instruments.
The bible of gas chromatography-offering everything the professional and the novice need to know about running, maintaining, and interpreting the results from GC Analytical chemists, technicians, and scientists in allied disciplines have come to regard Modern Practice of Gas Chomatography as the standard reference in gas chromatography. In addition to serving as an invaluable reference for the experienced practitioner, this bestselling work provides the beginner with a solid understanding of gas chromatographic theory and basic techniques. This new Fourth Edition incorporates the most recent developments in the field, including entirely new chapters on gas chromatography/mass spectrometry (GC/MS); optimization of separations and computer assistance; high speed or fast gas chromatography; mobile phase requirements: gas system requirements and sample preparation techniques; qualitative and quantitative analysis by GC; updated information on detectors; validation and QA/QC of chromatographic methods; and useful hints for good gas chromatography. As in previous editions, contributing authors have been chosen for their expertise and active participation in their respective areas. Modern Practice of Gas Chromatography, Fourth Edition presents a well-rounded and comprehensive overview of the current state of this important technology, providing a practical reference that will greatly appeal to both experienced chomatographers and novices.
This revised and updated edition includes new chapters on gas chromatography/mass spectrometry (GC/MS), optimizing separations using GC, forensic GC applications and GC injection systems. There is also expanded coverage of instrumentation.

The latest edition of the authoritative reference to HPLC High-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 conditions Equipment and detection The column—the "heart" of the HPLC system Reversed-phase separation, normal-phase chromatography, gradient elution, two-dimensional separation, and other techniques Computer simulation, qualitative and quantitative analysis, and method validation and quality control The separation of large molecules, including both biological and synthetic polymers Chiral separations, preparative separations, and sample preparation Systematic development of HPLC separations—new to this edition Troubleshooting tricks, techniques, and case studies for both equipment and chromatograms Designed 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.
During its short 20 year history High Performance Liquid Chro matography (HPLC) has won itself a firm place amongst the instrumental methods of analysis. HPLC has caused a revolution in biological and pharmaceutical chemistry. Approximately two thirds of the publications on HPLC are concerned with problems from this area of life science. Biotechnology, where it is necessary to isolate substances from complicated mixtures, is likely to give further impetus to the dissemination of modern liquid chromatog raphy in columns, particularly on the preparative scale. This book presents, by means of examples, the application of HPLC to various fields, as well as fundamental discussions of chromatographic methods. The quality of the analytical result is decisively dependent on the qualities of the equipment employed (by Colin, Guiochon, and Martin). Especially the demands are discussed that are placed on the components of the instrument including those for data acquisition and processing. The section on "quantitative analy sis" (by ABhauer, Ullner) covers besides the principles also the problems of ensuring the quality of the data in detail. The basic problems arising by enlarging the sample size to preparative di mensions and the requirements put on the aparatus are discussed in the section on "preparative applications" (by Wehrli).

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.
Contemporary Practice in Clinical Chemistry, Fourth Edition, provides a clear and concise overview of important topics in the field.
