Available in PDF, EPUB and Kindle. Book excerpt: A program to determine trace organic impurities present in helium has been initiated. The impurities were concentrated in a cryogenic trap to permit detection and identification by a gas chromatographic-mass spectrometric technique. Gaseous helium (GHe) exhibited 63 GC flame ionization response peaks. Relative GC peak heights and identifications of 25 major impurities by their mass spectra are given. As an aid to further investigation, identities are proposed for 16 other components, and their mass spectra are given.

Available in PDF, EPUB and Kindle. Book excerpt: The First International Symposium on the Interface between Analytical Chemistry and Microbiology: Applications of Chromatography and Mass Spectrometry was held June 1987 at the University of South Carolina, Columbia, SC, U.S.A. The purpose of the "Interface" meeting was to forge connections between analytical chemists and microbiologists that are using chromatography and mass spectrometry to solve common problems. The goals were admirably fulfilled. Nearly a hundred participants from seven European countries, Japan, and the United States participated in hearing twenty-three plenary talks and thirty-six submitted papers and posters. The papers and discussions displayed the breadth and depth of current research applications and revealed future directions. This book "Analytical Microbiology Methods: Chromatography and Mass Spectrometry" is loosely based on some of the presentations and discussions at the meeting. Each chapter describes specific methodology and applications in the context of the relevant scientific background. The present book continues the theme of an earlier book, "Gas Chromatography/Mass Spectrometry Applications in Microbiology", edited by G. Odham, L. Larsson, and P-A. Mardh, published by Plenum Press in 1984.

Download or read book Bretherick s Handbook of Reactive Chemical Hazards written by L. Bretherick and published by Butterworth-Heinemann. This book was released on 2013-10-22 with total page 2056 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bretherick's Handbook of Reactive Chemical Hazards, Fourth Edition provides information pertinent to the reactive hazards associated with the use of chemicals. This book discusses the development of the technologies, particularly in the area of safety research. Organized into two chapters, this edition begins with an overview of the advantages to be gained in grouping together elements or compounds showing similar reactivity or structure. This text then explores the underlying principles and practical aspects of minimizing reactive chemical hazards. Other chapters consider the rate of an exothermic chemical reaction, which determines the rate of energy release. This book discusses as well the factors that affect reaction kinetics, which are significant in relation to possible reaction hazards. The final chapter deals with reactions at high temperature that may be exceptionally hazardous attributed to the enhanced kinetic energy content of the system. This book is a valuable resource for chemists. Safety officers who are tasked for safety in industrial laboratories will also find this book extremely useful.

Download or read book Bretherick s Handbook of Reactive Chemical Hazards written by Peter Urben and published by Elsevier. This book was released on 2016-06-23 with total page 2509 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'Bretherick' is widely accepted as the reference work on reactive chemical hazards and is essential for all those working with chemicals. It attempts to include every chemical for which documented information on reactive hazards has been found. The text covers over 5000 elements and compounds and as many again of secondary entries involving two or more compounds. One of its most valuable features is the extensive cross referencing throughout both sections which links similar compounds or incidents not obviously related. The fifth edition has been completely updated and revised by the new Editor and contains documented information on hazards and appropriate references up to 1994, although the text still follows the format of previous editions. Volume 1 is devoted to specific information on the stability of the listed compounds, or the reactivity of mixtures of two or more of them under various circumstances. Each compound is identified by an UPAC-based name, the CAS registry number, its empirical formula and structure. Each description of an incident or violent reaction gives reference to the original literature. Each chemical is classified on the basis of similarities in structure or reactivity, and these groups are listed alphabetically in Volume 2. The group entries contain a complete listing of all the compounds in Volume 1 assigned to that group to assist cross referral to similar compounds. Volume 2 also contains hazard topic entries arranged alphabetically, some with lists. Appendices include a fire related data table for higher risk chemicals, indexes of registry numbers and chemical names as well as reference abbreviations and a glossary.
