Book Description
The second edition of Gas Chromatography and Mass Spectrometry: A Practical Guide follows the highly successful first edition by F.G. Kitson, B.S. Larsen, and C.N. McEwen (1996), which was designed as an indispensible resource for GC/MS practitioners regardless of whether they are a novice or well experienced. The Fundamentals section has been extensively reworked from the original edition to give more depth of an understanding of the techniques and science involved with GC/MS. Even with this expansion, the original brevity and simple didactic style has been retained. Information on chromatographic peak deconvolution has been added along with a more in-depth understanding of the use of mass spectral databases in the identification of unknowns. Since the last edition, a number of advances in GC inlet systems and sample introduction techniques have occurred, and they are included in the new edition. Other updates include a discussion on fast GC and options for combining GC detectors with mass spectrometry. The section regarding GC Conditions, Derivatization, and Mass Spectral Interpretation of Specific Compound Types has the same number of compound types as the original edition, but the information in each section has been expanded to not only explain some of the spectra but to also explain why certain fragmentations take place. The number of Appendices has been increased from 12 to 17. The Appendix on Atomic Masses and Isotope Abundances has been expanded to provide tools to aid in determination of elemental composition from isotope peak intensity ratios. An appendix with examples on "Steps to follow in the determination of elemental compositions based on isotope peak intensities" has been added. Appendices on whether to use GC/MS or LC/MS, third-party software for use in data analysis, list of information required in reporting GC/MS data, X+1 and X+2 peak relative intensities based on the number of atoms of carbon in an ion, and list of available EI mass spectral databases have been added. Others such as the ones on derivatization, isotope peak patterns for ions with Cl and/or Br, terms used in GC and in mass spectrometry, and tips on setting up, maintaining and troubleshooting a GC/MS system have all been expanded and updated. - Covers the practical instruction necessary for successful operation of GC/MS equipment - Reviews the latest advances in instrumentation, ionization methods, and quantitation - Includes troubleshooting techniques and a variety of additional information useful for the GC/MS practitioner - A true benchtop reference - A guide to a basic understanding of the components of a Gas Chromatograph-Mass Spectrometer (GC-MS) - Quick References to data interpretation - Ready source for information on new analyses

Book Description
Time-of-Flight Mass Spectrometry contains the proceedings of the First European Symposium on Time-of-flight Mass Spectrometry held at the University of Salford in the UK on July 3-5, 1967. The papers focus on time-of-flight mass spectrometry and its chemical applications, from flash photolysis and pyrolysis reactions to shock wave reactions and high-temperature studies of inorganic solids. This book is comprised of nine chapters and opens with an introduction to the MA-1 and other time-of-flight mass spectrometers, followed by their applications to studies of chemical reactions such as flash photolysis and pyrolysis reactions, reactions involving shock waves, and high-temperature studies of inorganic solids. Subsequent chapters explore fast recording techniques for time-resolved mass spectrometry; detection of the NH2 free radical and other ammoniacal complexes in the electrical discharge decomposition of ammonia gas; and reactions of ions with molecules in the gas phase and the sputtering of solid surfaces by ion bombardment. The use of a time-of-flight mass spectrometer in experimental investigations of negative ions is also described. This monograph will be a valuable resource for users of a time-of-flight mass spectrometer and allow non-users to become acquainted with its applications and advantages.

Book Description
Mass Spectrometry for the Clinical Laboratory is an accessible guide to mass spectrometry and the development, validation, and implementation of the most common assays seen in clinical labs. It provides readers with practical examples for assay development, and experimental design for validation to meet CLIA requirements, appropriate interference testing, measuring, validation of ion suppression/matrix effects, and quality control. These tools offer guidance on what type of instrumentation is optimal for each assay, what options are available, and the pros and cons of each. Readers will find a full set of tools that are either directly related to the assay they want to adopt or for an analogous assay they could use as an example. Written by expert users of the most common assays found in a clinical laboratory (clinical chemists, toxicologists, and clinical pathologists practicing mass spectrometry), the book lays out how experts in the field have chosen their mass spectrometers, purchased, installed, validated, and brought them on line for routine testing. The early chapters of the book covers what the practitioners have learned from years of experience, the challenges they have faced, and their recommendations on how to build and validate assays to avoid problems. These chapters also include recommendations for maintaining continuity of quality in testing. The later parts of the book focuses on specific types of assays (therapeutic drugs, Vitamin D, hormones, etc.). Each chapter in this section has been written by an expert practitioner of an assay that is currently running in his or her clinical lab. Provides readers with the keys to choosing, installing, and validating a mass spectrometry platform Offers tools to evaluate, validate, and troubleshoot the most common assays seen in clinical pathology labs Explains validation, ion suppression, interference testing, and quality control design to the detail that is required for implementation in the lab

Book Description
This book presents the basic principles of time-of-flight (TOF) mass spectrometry with a strong emphasis on applications in biological research. It describes many innovative techniques, including orthogonal extraction, post source decay, and delayed extraction, and surveys ionization techniques used on TOF mass spectrometers such as electron impact, plasma desorption, SIMS, FAB, laser desorption, MALDI, and electrospray. The book features chapters on applications to peptides/proteins, oligonucleotides, and other biological macromolecules, and examines how techniques might be used in sequencing the human genome.
