Download or read book Selected Ion Fragmentation with a Triple Quadrupole Mass Spectrometer written by Richard Alan Yost and published by . This book was released on 1979 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: A triple quadrupole mass spectrometer (TOMS) has been designed and developed for the direct analysis of mixtures and the elucidation of molecular structures. In the TOMS, several ionic species are generated from a sample, ions of a particular mass are selected for fragmentation, and the resulting fragment ions are mass analyzed. The instrument consists of, in series, a dual chemical ionization/electron impact (CI/EI) ionization source, a quadrupole mass filter, an RF-Only quadrupole that can be pressurized with a collision gas, a second quadrupole mass filter, and an electron multiplier. The ion fragmentation process is performed by collision-induced dissociation (CID) in the RF-only quadrupole collision chamber. The instrument is described and its performance evaluated. For structure elucidation, the formation and fragmentation of every fragment ion from a compound can be directly determined. For mixture analysis, the first mass analyzer can separate the mixture components as their molecular ions, produced by soft ionization (e.g., CI) of the sample. The fragmentation spectra of the individual components can then be obtained by fragmenting the selected molecular ions and scanning the second analyzer. The identification of isomeric and isobaric compounds in a mixture is demonstrated. Detection limits of ten to the minus 15th power mole for methane and nitrobenzene are shown.

Available in PDF, EPUB and Kindle. Book excerpt: Plant Hormones: Biosynthesis and Mechanisms of Action is based on research funded by the Chinese government's National Natural Science Foundation of China (NSFC). This book brings a fresh understanding of hormone biology, particularly molecular mechanisms driving plant hormone actions. With growing understanding of hormone biology comes new outlooks on how mankind values and utilizes the built-in potential of plants for improvement of crops in an environmentally friendly and sustainable manner. This book is a comprehensive description of all major plant hormones: how they are synthesized and catabolized; how they are perceived by plant cells; how they trigger signal transduction; how they regulate gene expression; how they regulate plant growth, development and defense responses; and how we measure plant hormones. This is an exciting time for researchers interested in plant hormones. Plants rely on a diverse set of small molecule hormones to regulate every aspect of their biological processes including development, growth, and adaptation. Since the discovery of the first plant hormone auxin, hormones have always been the frontiers of plant biology. Although the physiological functions of most plant hormones have been studied for decades, the last 15 to 20 years have seen a dramatic progress in our understanding of the molecular mechanisms of hormone actions. The publication of the whole genome sequences of the model systems of Arabidopsis and rice, together with the advent of multidisciplinary approaches has opened the door to successful experimentation on plant hormone actions. - Offers a comprehensive description of all major plant hormones including the recently discovered strigolactones and several peptide hormones - Contains a chapter describing how plant hormones regulate stem cells - Offers a fresh understanding of hormone biology, particularly molecular mechanisms driving plant hormone actions - Discusses the built-in potential of plants for improvement of crops in an environmentally friendly and sustainable manner
