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.
"In full colour throughout, this book describes the power of mass spectrometry in resolving environmental issues, demonstrating how real-world complex problems can be solved in a simple and elegant way."--Worldcat.
Whereas some "microarray" or "bioinformatics" scientists among us may have been criticized as doing "cataloging research", the majority of us believe that we are sincerely exploring new scientific and technological systems to benefit human health, human food and animal feed production, and environmental protections. Indeed, we are humbled by the complexity, extent and beauty of cross-talks in various biological systems; on the other hand, we are becoming more educated and are able to start addressing honestly and skillfully the various important issues concerning translational medicine, global agriculture, and the environment. The two volumes of this book present a series of high-quality research or review articles in a timely fashion to this emerging research field of our scientific community.
The Twentieth Jerusalem Symposium reflected the high standards of these distinguished scientific meetings which convene once a year at the Israel Academy of Sciences and Humanities in Jerusalem to discuss a specific topic in the broad area of quantum chemistry and biochemistry. The Twentieth Jerusalem Symposium marked an auspicious occasion. commemorating two decades of this scientific endeavour. The topic at this year's Jerusalem Symposium was Large Finite Systems which constitutes a truly interdisciplinary subject of central interest in the broad areas of chemistry. physics. astrophysics and biophysics. The main theme of the Symposium was built around bridging the gap between molecular. su...
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 ...
The different LC-MS techniques available today were developed to suit specific analytical needs and the application range covered by each one is wide, but still limited. GC amenable compounds can be all analyzed with a single GC-MS system whereas HPLC applications call for specific LC-MS instrumental arrangements. ESI, APCI, APPI, and EI are ionization techniques that can be combined with different analyzers, in single or tandem configuration, to create the ultimate system for a certain application. Once approaching LC-MS for a specific need, the fast technical evolution and the variegated commercial offer can induce confusion in the potential user.The role of this book is to enlighten the s...
Completely revised and updated, this text provides an easy-to-read guide to the concept of mass spectrometry and demonstrates its potential and limitations. Written by internationally recognised experts and utilising "real life" examples of analyses and applications, the book presents real cases of qualitative and quantitative applications of mass spectrometry. Unlike other mass spectrometry texts, this comprehensive reference provides systematic descriptions of the various types of mass analysers and ionisation, along with corresponding strategies for interpretation of data. The book concludes with a comprehensive 3000 references. This multi-disciplined text covers the fundamentals as well as recent advance in this topic, providing need-to-know information for researchers in many disciplines including pharmaceutical, environmental and biomedical analysis who are utilizing mass spectrometry
The Twenty Fourth Jerusalem Symposium reflected the high standards of these distinguished scientific meetings, which convene once a year at the Israel Academy of Sciences and Humanities in Jerusalem to discuss a specific topic in the broad area of quantum chemistry and biochemistry. The topic at this year's Jerusalem Symposium was mode selective chemistry, which constitutes a truly interdisciplinary subject of central interest in the areas of chemical physics, photochemistry and photobiology. The main theme of the Symposium was built around the exploration of the possibility and conditions for non-statistical reaction dynamics in molecules, van der Waals molecules, clusters and condensed pha...
While it is not possible to predict or necessarily prevent terrorist incidents in which chemical warfare agents (CWAs) and toxic industrial chemicals (TICs) are deployed, correctly chosen, fast, and reliable detection equipment will allow prepared rescue workers to respond quickly and minimize potential casualties.

For a world mired in catastrophe, nothing could be more urgent than the question of survival. In this theoretically and methodologically groundbreaking book, Adam Y. Stern calls for a critical reevaluation of survival as a contemporary regime of representation. In Survival, Stern asks what texts, what institutions, and what traditions have made survival a recognizable element of our current political vocabulary. The book begins by suggesting that the interpretive key lies in the discursive prominence of "Jewish survival." Yet the Jewish example, he argues, is less a marker of Jewish history than an index of Christianity's impact on the modern, secular, political imagination. With this invers...
