Summary

Proton transfer reaction mass spectrometry (PTR-MS) is a specialist technique for detecting and identifying very small quantities amounts of organic gases in air. It is used mostly in atmospheric research, but also has applications in environmental science, pollution science, food science, and medical diagnosis. It is used as a monitoring system in various industries, e.g. measuring volatile organic compounds (VOCs) emitted by waste incineration plants.Proton Transfer Reaction Mass Spectrometry and Related Techniques is the first book devoted to PTR-MS and provides a comprehensive account of the technique. Written by leading researchers and covering the basic principles, experimental techniques, and a detailed account of its various applications, this book is essential reading for researchers, technicians, postgraduate students and professionals in industry.

Author Biography

Andrew Ellis and Paul Monks are both in the Department of Chemistry, University of Leicester. They are in the process of writing the first comprehensive review of PTR-MS to be published in Chemical Reviews later this year. Ellis is lead author of Electronic and Photoelectron Spectroscopy (2005) published by Cambridge University Press.
