Although GC-MS (gas chromatography–mass spectrometry) finds applications in fields as diverse as the food processing industry, medicine, pharmacology, and environmental analysis, the few works that are dedicated to this use of mass spectrometry are generally highly complex and theoretical. Emphasizing the practical aspects of GC-MS, without neglecting the fundamental theory, Introduction to GC-MS Coupling addresses both novice and experienced users of this technique. It presents GC-MS in a clear, instructive way and proposes solutions for the difficulties classically encountered by users. The book begins with the core principles of gas chromatography and its specific uses with MS detectors. It discusses generalities of mass spectrometry, including the various types of MS detectors and insight into the vacuum necessary for efficient operation. Chapters cover the types of analyzers used in GC-MS and their functioning principles, with a focus on the commonly used quadrupolar analyzers, as well as the implementation, advantages, and limits of various modes of acquisition in GC-MS. The text also compares performance and limitations of quadrupolar analyzers. The author includes a full chapter on quantification using GC-MS, a topic that can be puzzling for many chemists. Encouraging a critical approach to databases, he compares laboratory-made and commercial mass spectra databases, and describes a database research algorithm. The final chapter examines mass spectra interpretation, covering chemistry concepts such as inductive and mesomeric effects required to understand dissociation pathways, and presents a global strategy for mass spectra interpretation.

Time is an important factor in physical and natural sciences. It characterizes the progress of chemical and biochemical processes. Mass spectrometry provides the means to study molecular structures by detecting gas-phase ions with the unique mass-to-charge ratios. Time-resolved mass spectrometry (TRMS) allows one to differentiate between chemical states that can be observed sequentially at different time points. Real-time mass spectrometric monitoring enables recording data continuously with a specified temporal resolution. The TRMS approaches – introduced during the past few decades – have shown temporal resolutions ranging from hours down to microseconds and beyond. This text covers the key aspects of TRMS. It introduces ion sources, mass analyzers, and interfaces utilized in time-resolved measurements; discusses the influence of data acquisition and treatment; finally, it reviews most prominent applications of TRMS – in the studies of reaction kinetics and mechanism, physicochemical phenomena, protein structure dynamics, biocatalysis, and metabolic profiling. It will assist science and engineering students to gain a basic understanding of the TRMS concept, and to recognize its usefulness. In addition, it may benefit scientists who conduct molecular studies in the areas of chemistry, physics and biology.
