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.

Gas chromatography–mass spectrometry (GC-MS) is a powerful way to analyse a range of substances. It is used in everything from food safety to medicine. It has even been used to protect endangered vultures through analysis of poisonous pesticide molecules in their environment! I want to apply this technique, where do I begin? Is GC-MS is the right technique to use? How do I prepare my samples and calibrate the instruments? This textbook has the answers to all these questions and more. Throughout the book, case studies illustrate the practical process, the techniques used and any common challenges. Newcomers can easily search for answers to their question and find clear advice with coloured images on how to get started and all subsequent steps involved in using GC-MS as part of a research process. Readers will find information on collecting and preparing samples, designing and validating methods, analysing results, and troubleshooting. Examples of pollutant, food, oil and fragrance analysis bring the theory to life. The authors use their extensive experience teaching GC-MS theory and practice and draw on their combined backgrounds applying the technique in academic and industry settings to bring this practical reference together. The authors also design and teach the Royal Society of Chemistry’s Pan Africa Chemistry Network GC-MS course, which is supported by GSK.

This volume provides an overview of the state of the art in gas chromatography with an emphasis on new technologies. The authors-all drawn from respected industrial and academic laboratories-consider developments in gas chromatographic techniques over the last decade. Application areas are addressed within individual chapters.

Principles and Practice of Modern Chromatographic Methods, Second Edition takes a comprehensive, unified approach in its presentation of chromatographic techniques. Like the first edition, the book provides a scientifically rigid, but easy-to-follow presentation of chromatography concepts that begins with the purpose and intent of chromatographic theory - the “what and why that are left out of other books attempting to cover these principles. This fully revised second edition brings the content up-to-date, covering recent developments in several new sections and an additional chapter on composite methods. New topics include sample profiling, sample preparation, sustainable green chemistry, 2D chromatography, miniaturization/nano-LC, HILIC, and more. Contains thorough chapters that begin with an updated schematic overview and a visual representation of the content Avoids the obfuscation of different terminologies and classification systems that are prevalent in the area, such as the relationship between liquid chromatography and column chromatography Provides integrated and comprehensive topic coverage based on chromatographic bibliometrics and survey reports on the relative usage of chromatographic techniques
