Download or read book Gas Chromatography Mass Spectrometry with Cold EI Leading the Way to the Future of GC MS written by Aviv Amirav and published by Scientific Research Publishing, Inc. USA. This book was released on 2021-08-30 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gas chromatography-mass spectrometry (GC-MS) with supersonic molecular beams (SMB) (also named GC-MS with Cold EI) is based on GC and MS interface with a SMB and on the electron ionization (EI) of vibrationally cold analytes in the SMB (hence the name Cold EI) in a contact-free fly-through ion source. Cold EI improves all the central GC-MS performance aspects and brings a broad range of important benefits thereby leading the way to the future of GC-MS. Cold EI provides enhanced molecular ions combined with effective library-basedsample identification. Sample identification is further improved by the use of powerful TAMI software that is based on isotope abundance analysis and improved quadrupole mass accuracy for the provision of the sample elemental formula from its molecular ion group of isotopologues.

This book was released on 2011-05-17 with total page 633 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

Available in PDF, EPUB and Kindle. Book excerpt: The book begins by covering the basic principles of both gas chromatography (GC) and mass spectrometry (MS) to the extent necessary to understand and deal with the data generated in a GC-MS analysis. The focus then turns to the particular requirements created by a direct combination of these two techniques into a single instrumentation system. The data generated and their use are covered in detail. The role of the computer and its specific software receives special attention, especially in the matter of compound identification via mass spectral search techniques. GC-MS-computer instrumentation has reached such a plateau of excellence today that the present commercial systems will not be obsolete for a long time to come. Therefore, a detailed description of these systems is not only informative but is also pertinent to the subject matter of this book. Finally, representative applications and results obtained with GC-MS-computer techniques are presented and chosen in such a way as to permit extrapolation of specific applications to similar problems encountered by the reader. To aid the reader in mastering the subject matter and increase understanding, interpretation problems and suggested readings are included. The format is instructional, informative and application-oriented with material presented in such a way as to be useful to a broad spectrum of people. The book serves as a text in its own right. The software package Gas Chromatography-Mass Spectrometry: A Knowledge Base, by F.A. Settle, Jr. and M.A. Pleva provides rapid access to a wealth of current information in the GC-MS field. Its three diskettes (51/4 inch) allow the user three ways to access: the index mode, the tree mode and a keyword search mode. The package may be purchased separately and is available for the IBM-PC and compatibles. The software provides a valuable supplement to the book.

This book was released on 2013-11-11 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: During recent years there has been increasing interest in the value of a number of chemical and physical-chemical analytical methods for the detection and characterization of microorganisms. Furthermore, such methods are currently used in studies on microbial metabolic processes, on the role of microorganisms in the turnover of inorganic and organic compounds, and on the impact on environmental changes by microbial activity. Moreover, the introduction of some of these methods not only shortens the analytical time period compared to ·'traditional" techniques, but also improves the analytical quality. Mass spectrometry (MS) combined with chromatographic inlet systems, particularly gas chromatography (GC), belongs to those methods which during recent years have established their value for the above-mentioned purposes. The present volume starts with basic chapters on the principles for MS and common inlet systems, particulary Gc. It discusses applications of these techniques to a number of microbiological disciplines, e.g., ecologi cal and medical microbiology. Emphasis is laid on organic compound classes vii viii / PREFACE of special relevance to microbiology, e.g., volatiles, lipids, amino acids, peptides and carbohydrates. Some compound classes of a more general biochemical rather than specific microbiological importance, e.g., steroids and nucleotides, are dealt with briefly. The editors wish to thank all those who have contributed to this book. We hope it will stimulate further research in this futuristic field and will be of practical value.
