Preface
This book began as a small series of brief articles designed to assist engineers and salesmen in
understanding some aspects of ion chemistry and mass spectrometry. Each article was composed
of a very short summary and a longer section that described aspects of the subject matter in
somewhat greater detail. To facilitate rapid reading and assimilation, extensive use was made of
figures and tables, which contain additional information in their legends or footnotes.
From the outset of writing these articles, it was never intended that they should be exhaustively
comprehensive, because this approach would have defeated the aims of the whole exercise, viz.,
the provision of short, quick explanations of major elements of mass spectrometry and closely
allied topics. The traditional, more all-embracing approach to writing about mass spectrometry was
left to the many excellent authors, who have provided impressive textbooks. In contrast, the major
objective of the
series was the provision of quick explanations of fundamental
concepts in mass spectrometry, without overelaboration. As far as possible, descriptions of pro-
cesses, applications, and underlying science were made with a minimum of text backed up by
easily and rapidly understood pictures. Although some major equations of relevance to mass
spectrometry have been introduced, the mathematical derivations of these equations were largely
omitted. This was not an attempt to dumb down an important discipline. Rather, the intent was to
make some of the esoteric aspects of an important area of analysis readily comprehensible to the
many people who have to deal with mass spectrometers but who have not been trained specifically
in this branch of science and engineering. The series began about ten years ago and encompasses
recent and past developments in mass spectrometry. However, since it is the principles of mass
spectrometry that are explained and not specific instrumentation, the information content remains
as relevant now as it was ten years ago.
The effort to clarify and articulate the principles of spectrometry as simply as possible
appears to have struck a welcome response among those who use mass spectrometers. The
original series was not advertised, but, once it had been discovered outside the Micromass
organization, there were inquiries as to how it could be purchased. From the start, Micromass
offered the series free in a ring-binder format and later also provided it free on CD ROM and
then on the Internet. Updating of the first CD led to over 600 requests for it on the day after its
release had been announced on the Internet. Partly because of this response — but mainly because
users or potential users frequently like to have a traditional reference book — it was decided to
publish the series in this present book form.
This preface would not be complete without the authors sincerely thanking a number of people
and, in particular, Micromass U.K. for its past keen support and for its permission to proceed with
publishing this book. A successful business is composed of enthusiastic people, and it would be
remiss of the authors not to thank all those many individuals in Micromass who have provided
countless pieces of advice and help. Lastly, the authors wish to acknowledge with gratitude the
support of Norman Lynaugh, Tony Hickson, and especially John Race for his original perspicacious
decision to encourage the series to go ahead and for the ideas he proffered throughout. As he once

famously remarked, “There are a lot of poor souls out there who are being asked to run mass
spectrometers but who know next to nothing about mass spectrometry.” At least we think it was
“souls” he said!
