During the past ten years a variety of methods involving mass
spectrom etry have been developed for the analysis of
environmentally important compounds. Much has been accomplished in
that period to solve some of the important problems in the field.
Growth of this methodology and its accomplishments has reached the
point where an individual scientist can no longer have an in-depth
knowledge of all the areas involved. We have attempted to provide
this in-depth picture to those scientists con cerned by having the
important topics treated by experts in the subject matter. In order
to provide all the relevant material in one volume we begin with
the general topics which provide the basic background material
necessary to understand the techniques discussed in the in-depth
topics. These general chapters are kept brief, containing only the
essentials needed by the working scientist to deal with the
practical applications. References in these chapters are chosen to
permit a more complete study of each chapter. The concept for this
book was developed during the activities of two of the editors
under a NATO travel grant. These editors gratefully acknowledge
this support which made the initial planning of this book possible.
The editors would like to thank the individual authors of each chap
ter for their cooperation and generously giving of their time for
this project."
The book begins by covering the basic principles of both gas
chromatography (GC) and mass spectrometry (MS) to the extent
necessary to understand and deal with the data generated in a GC-MS
analysis. The focus then turns to the particular requirements
created by a direct combination of these two techniques into a
single instrumentation system. The data generated and their use are
covered in detail. The role of the computer and its specific
software receives special attention, especially in the matter of
compound identification via mass spectral search techniques.
GC-MS-computer instrumentation has reached such a plateau of
excellence today that the present commercial systems will not be
obsolete for a long time to come. Therefore, a detailed description
of these systems is not only informative but is also pertinent to
the subject matter of this book. Finally, representative
applications and results obtained with GC-MS-computer techniques
are presented and chosen in such a way as to permit extrapolation
of specific applications to similar problems encountered by the
reader. To aid the reader in mastering the subject matter and
increase understanding, interpretation problems and suggested
readings are included. The format is instructional, informative and
application-oriented with material presented in such a way as to be
useful to a broad spectrum of people.
The book serves as a text in its own right.
The software package Gas Chromatography-Mass Spectrometry: A
Knowledge Base, by F.A. Settle, Jr. and M.A. Pleva provides rapid
access to a wealth of current information in the GC-MS field. Its
three diskettes (51/4 inch) allow the user three ways to access:
the index mode, the tree mode and a keyword search mode. The
package may be purchased separately and is available for the IBM-PC
and compatibles.
The software provides a valuable supplement to the book.
