Gas Chromatography (GC) is undoubtedly the most widely used technique for the separation and analysis of volatile compounds. Yet comprehensive guides to contemporary GC theory and practice are surprisingly hard to find.Basic Gas Chromatography fills this significant void in the GC literature. Written by two well-known practitioners and educators in GC, it offers thorough coverage of the basic principles and techniques of modern gas chromatography.Designed to serve as a primer/working reference for bench chemists and as a textbook for upper-level undergraduate and graduate students, it presents the fundamentals in a straightforward and logical fashion. Theoretical issues are explained without complicated equations and derivations and always in terms of how they relate to practical operating principles. Timely, comprehensive, and accessible, Basic Gas Chromatography:* Provides a balanced presentation of theory and practice* Includes both capillary column and packed column chromatography* Uses the new IUPAC terms throughout, cross-referenced to traditional terms and symbols* Offers a wealth of helpful hints, step-by-step guidelines, and trouble-shooting tips* Briefly covers GC-MS, headspace analysis, chiral analysis, solid phase microextraction, and other cutting-edge topics.

This revision brings the reader completely up to date on the evolving methods associated with increasingly more complex sample types analyzed using high-performance liquid chromatography, or HPLC. The book also incorporates updated discussions of many of the fundamental components of HPLC systems and practical issues associated with the use of this analytical method. This edition includes new or expanded treatments of sample preparation, computer assisted method development, as well as biochemical samples, and chiral separations.

Major advances in instrumentation and technology have made high-performance liquid chromatography (HPLC) a pervasive tool in virtually all areas of chemical and biomedical research today. Despite HPLC's enormous growth, technical problems still bedevil most users at least occasionally. Based on their immensely successful short courses, Dolan and Snyder's landmark new book --Troubleshooting LC Systems--now makes available to every practicing chromatographer the authors' wealth of expertise from years of hands-on troubleshooting of real-world LC problems--problems that routinely cause crises and unproductive downtime in nearly every lab. Believing that successful troubleshooting requires an understanding of the basics, Dolan and Snyder open by setting forth all the fundamental principles of LC operation, then move on to a microscopic description of all the elements of LC devices, to lay out their optimal preventive maintenance routines, and ultimately to offer an unprecedentedly thorough treatment of each and every facet of troubleshooting. Displaying a special tutorial mastery--honed to a fineness during their ongoing teaching and consulting activities, and a well-received feature column in LC Magazine--the book's chapters cover: automation and robotics • approaches to troubleshooting • reactions of samples • basic separation techniques • valves, tubing, syringes • band broadening and tailing • preventive maintenance • column packing and flushing • individual LC modules • troubleshooting principles • reagents and buffering • specific problems in separation • ghost and vacancy peaks • quantitation and calibration • pumps, seals, and pistons • gradient elution problems • column composition • concentration and blockages • sample cleanup • temperature and mixing effects • detectors and recorders • column packing and flushing. In short, Dolan and Snyder's eminently practical new guide to Troubleshooting LC Systems is an essential laboratory handbook--one that empowers expert and novice chromatographer alike to solve every sort of practical laboratory problem on a day-to-day basis. No one using an LC system should be without it!

Updated and expanded, the classic guide to GC/MS helps chromatographers quickly learn to use this technique for analyzing and identifying compounds. After explaining the fundamentals, it discusses optimizing, tuning, using, and maintaining GC/MS equipment; explores advances in miniaturized and field-portable GC/MS systems and microfluidic components; and more. Complete with a CD-ROM, it covers applications in the environmental laboratory and in forensics, toxicology, and space science. This is the premier resource for professionals in those fields and for students.

This book describes a powerful and effective tool for the molecular biologist researcher. Readers will discover how DNA chromatography can be used in their own work. Intended as an introduction for the molecular biologist reader, this will also serve as a practical guide for the experienced user. The clear and concise writing style is also attractive to the chemist who wants to learn more about molecular biology.

The bible of gas chromatography-offering everything the professional and the novice need to know about running, maintaining, and interpreting the results from GCAnalytical 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 all-new edition of the highly successful first edition contains a wealth of up-to-date information on this major analytical technique. Ion-exchange, ion-exclusion, and ion-pair chromatography are treated together with their detection methods, and a discussion of quantitative analysis is also given. The complete range of application possibilities of this technique is described and illustrated with numerous chromatograms. Special chapters are featured on applications in environmental analysis, clinical chemistry as well as in the food and beverage industry. From reviews of previous editions:This volume can be highly recommended to both the experienced user and the newcomer in the field of ion chromatography. Zeitschrift fuer Wasser- und AbwasserforschungEverybody who is actively dealing with ion chromatography cannot afford to miss this book. LaborpraxisThis book is a valuable aid to all scientists wishing to work confidently with these different methods, as well as practitioners who employ these techniques on a day-to-day basis.

This book shows the chemist who is already familiar with the basics of HPLC how to develop HPLC separation methods for a wide variety of situations. It focuses mainly on reversed-phase separations of small-molecules, but also addresses development of normal-phase and ion-pair separations. The authors introduce the use of computers to speed and improve method development, covering commercially available HPLC programs.

Unifies the complex welter of techniques used for chemical separations by clearly formulating the concepts that are common to them. The mass transport phenomena underlying all separation processes are developed in a simple physical-mathematical form. The limitations and optimum performance of alternative separation techniques and the factors enhancing and limiting separation power can thus be described and explored. Generously illustrated and contains numerous exercises. Long awaited in the scientific community, it breaks new ground in understanding separation processes.
