Book Description
The only comprehensive reference on this popular and rapidly developing technique provides a detailed overview, ranging from fundamentals to applications, including a section on the evaluation of GC-MS analyses. As such, it covers all aspects, including the theory and principles, as well as a broad range of real-life examples taken from laboratories in environmental, food, pharmaceutical and clinical analysis. It also features a glossary of approximately 300 terms and a substance index that facilitates finding a specific application. For this new edition the work has been now extended to two volumes, reflecting the latest developments in the technique and related instrumentation, while also incorporating several new examples of applications in many fields. The first two editions were very well received, making this handbook a must-have in all analytical laboratories using GC-MS.

Book Description
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.

Book Description
This book enables the reader to gain a rapid understanding of GC/MS analysis through a basic knowledge of the fundamental principles, linking these with simple and practical applications in the field of industrial medicine and analysis of drugs. Additional information from other specialist fields is also provided with the aim of helping the analyst to understand their relevance to the interpretation of results. The book describes efficient methods of sample preparation and quality assurance and provides information on epidemiology and pharmacology, without which drug screening is impossible. This comprehensive overview is mainly written for the practical analyst in the clinical laboratory but it is equally suited for teaching purposes.

Book Description
An essential guide to the proven automated sample preparation process While the measurement step in sample preparation is automated, the sample handling step is manual and all too often open to risk and errors. The manual process is of concern for accessing data quality as well as producing limited reproducibility and comparability. Handbook of Automated Sample Preparation for CG-MS and LC-MS explores the advantages of implementing automated sample preparation during the handling phase for CG-MS and LC-MS. The author, a noted expert on the topic, includes information on the proven workflows that can be put in place for many routine and regulated analytical methods. This book offers a guide to automated workflows for both on-line and off-line sample preparation. This process has proven to deliver consistent and comparable data quality, increased sample amounts, and improved cost efficiency. In addition, the process follows Standard Operation Procedures that are essential for audited laboratories. This important book: Provides the information and tools needed for the implementation of instrumental sample preparation workflows Offers proven and detailed examples that can be adapted in analytical laboratories Shows how automated sample preparation can reduce cost per sample, increase sample amounts, and produce faster results Includes illustrative examples from various fields such as chemistry to food safety and pharmaceuticals Written for personnel in analytical industry, pharmaceutical, and medical laboratories, Handbook of Automated Sample Preparation for CG-MS and LC-MS offers the much-needed tools for implementing the automated sample preparation for analytical laboratories.

Book Description
L’analyse des traces des pesticides dans les eaux et surtout dans l’eau potable peut donner des informations de pollution de l’eau et pour de santé humaine. La présence d’un grand nombre de pesticides de différentes propriétés dans l’eau rend difficile de choisir une méthode d’analyse multirésiduelle. Cependant les résultats publiés étant souvent contradictoires, nous avons réalisé des études des paramètres d’extraction (choix de cartouches d’extraction, nature de solvant, pH, ...), et des méthodes d’analyses. Nous nous sommes intéressés à l’extraction sur phase solide (SPE) et à différentes méthodes d’analyses : L’électrochimie (polarographie), la chromatographie en phase gazeuse couplée à la spectrométrie de masse (GC – MS) et la chromatographie en phase liquide couplée à la spectrométrie de masse (LC – MS/MS). Nous avons réalisé la validation de la méthode pour 34 pesticides analysés par chromatographie en phase gazeuse après la vérification des critères de robustesse, la linéarité, de répétabilité, de spécificité et de justesse et la détermination des limites de détection et de quantification. Les limites de détection et de quantification ont mesurés par pour 9 pesticides par polarographie chromatographie en phase liquide et par polarographie impulsionnelle pour 6 pesticides étudiés après avoir comparé avec les résultats obtenus par les méthodes de séparations

Book Description
La réglementation en matière de sécurité alimentaire impose des exigences de plus en plus strictes notamment au niveau des produits phytosanitaires. Les méthodes analytiques multi-résidus de pesticides se doivent de suivre cette évolution et d'être performantes afin d'atteindre des limites de quantification compatibles avec les limites maximales de résidus. Parmi ces méthodes, la chromatographie en phase gazeuse avec détection spécifique (ECD, NPD, ...) est largement utilisée, mais ne permet pas de résoudre les phénomènes de co-élution, d'effets matrice ou d'interférences. Les développements récents de la GC/MS/MS permettent de pallier ces problèmes analytiques en sélectionnant un ion caractéristique du composé cible qui est ensuite excité afin de produire un spectre de dissociation en ion fils. La sensibilité et la spécificité des résultats s'en trouvent accrues. Une partie du travail de ce mémoire est consacré au développement d'une méthodologie d'optimisation des conditions de détection GC/MS/MS à l'aide d'un piège ionique quadripolaire. Le but était de développer une méthode utilisable en analyses de routine, pour identifier et quantifier les résidus de pesticides dans des matrices végétales. Pour cela, deux méthodes ont été étudiées et comparées pour douze produits phytosanitaires représentatifs des matières actives utilisées en agriculture. La méthode A, exhaustive, étudie l'influence du paramètre de stabilité qz sur l'efficacité du processus de dissociations induites par collision (n cid) en fonction de l'amplitude d'excitation non résonnante Vp-p appliquée à l'ion précurseur. La méthode B, plus automatique, consiste à travailler à un paramètre qz fixe afin de déterminer rapidement l'amplitude d'excitation. L'application de cette dernière méthode à l'analyse de résidus dans les matrices végétales et sa comparaison avec les détections GC/ECD et GC/TSD démontre les réelles perspectives offertes par la GC/EI/MS/MS.
