Book excerpt: This encyclopedia is composed of an eight-volume set that provides an overview of the field of environmental analysis. The contents are divided into major content areas including air pollution control, environmental law, and environmental sampling. Thevolumes are organized alphabetically with each article signed by the author(s). The individual articles begin with a summary of the topic heading and then divide the text into subtopics indicated by boldface headings.The articles are written clearly, however, the authors assume a basic knowledge of chemistry and math on the part of the reader. For example, the acid mine drainage article refers to the Arrhenius equation, but does not clarify this statement in the text. Each article contains graphs as well as pictures to illustrate points made in the text. The articles are long and provide a detailed explanation of each topic. The authors also provide a bibliography at the end of each article.Special features of the encyclopedia include a list of contributors, a table of conversion factors and a list of abbreviations and acronyms. The preface outlines the general contents of the encyclopedia. The preface also includes sections that suggest the target audience and recommended usages for the set. The final volume of the set contains an alphabetic index to the topics contained in the volumes.

This book was released on 2007-10-31 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ionization Methods in Organic Mass Spectrometry is a basic practical guide for scientists of all disciplines who wish to analyse samples by organic mass spectrometry. Concentrating on instrumental operation, this book gives step-by-step instructions on how to set up, and how to achieve the best results, using a range of ionization methods, including atmospheric pressure chemical ionization, electrospray ionization and matrix assisted laser desorption ionization. Ionization Methods in Organic Mass Spectrometry will enable a beginner, or practitioner with limited experience, to choose the most appropriate ionization technique in application areas such as biomolecules, drugs and metabolites, pesticides, polymers and many other organic compounds. It will be a valuable practical guide for technicians, graduates, students or researchers - or indeed anyone new to practical organic mass spectrometry.
Download or read book Development of Mass Spectrometry Techniques for Real time Reaction Monitoring written by Eric Janusson and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Electrospray ionization (ESI) facilitates the transfer of ions in solution into the gas-phase for analysis by mass spectrometry. The ionization process is intricate and required further investigation, especially because of the lack of in-depth literature on the subject. Furthermore, investigations into the ESI process will serve to assist development of real-time reaction monitoring. To do this, a cationic ionic liquid, butyl methylimidazolium, [BMIM]+, was paired with several counterions and mixed in various solvents. This was analyzed by ESI mass spectrometry to determine the relative response ratio between two observable aggregates. The findings assisted in the elucidation of differential surface activity of chemically distinct ions in ESI, with respect to changes in solvent. Furthermore, the results obtained suggested acetonitrile is an optimal solvent for the analysis of ions of this type due to a reduction in differential effects, whereas other common ESI solvents prove to enhance the surface activity of specific aggregate ions. Further investigations into ESI-MS involved effects of spray head geometry relative to the inlet to the mass spectrometer. The position of the spray-head, the solvent, and additional instrumental parameters were independently adjusted during the analysis of an equimolar mixture of two different ions. It was found that these parameters have dramatic effects on the distribution of signal intensity from one ion to another, and therefore the resulting usefulness of acquired spectra. The sharp contrast in ion intensity, and even differential ion activity, with relatively minor instrument changes (such as temperature programming, gas flow rates and solvent choice) demonstrated the importance of finding the optimal spot for the ESI spray head, especially when signal intensity and a quality analysis is key. Additional ESI-MS work involved working with an industry partner to develop selective charge-tagging reagents for the characterization of petroleum fractions by ESI-MS. A simple chemical derivatization technique was developed in which thiols and disulfides may be selectively analyzed in a complex matrix and easily characterized. These reagents enhanced detection of thiols and disulfides solely due to the nature of the charged tag derivatization agent. The charged disulfides readily and exclusively react with thiols in a complex matrix in a short amount of time. The synthesis of these reagents was simple and resulted in a pure and stable reagent. The efficacy of the reaction was demonstrated using on-line monitoring, while the scope and usefulness of the reaction was demonstrated in petroleum fractions. A combination of UV-Vis spectroscopy and electrospray ionization mass spectrometry was used for real-time monitoring of Pd2(dba)3 activation with sulfonated versions of PPh3 and a Buchwald-type ligand. This provides insight into the effect of ligand and preparation conditions on activation and allows for establishment of rational activation protocols. It is expected that this reaction monitoring technique will be enhanced through the use of tandem mass spectrometry. Finally, an experimental method of visualizing atomic orbitals was developed as a demonstration intended for first year chemistry students. This demonstration involved the examination of nodal and anti-nodal regions of Chladni figures which students could then connect to the concept of quantum mechanical parameters and their relationship to atomic orbital shape.
