The second edition of Gas Chromatography and Mass Spectrometry: A Practical Guidefollows thehighly successfulfirstedition 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 spectral databases in the identification of unknowns. Since the last edition, a number of advances in GC inlet systems and sample introduction techniques have occurred, and they are included in the new edition. Other updates include a discussion on fast GC and options for combining GC detectors with mass spectrometry. The section regarding GC Conditions, Derivatization, and Mass
Spectral Interpretation of Specific Compound Types has the same
number of compound types as the original edition, but the
information in each section has been expanded to not only explain
some of the spectra but to also explain why certain fragmentations
take place. The number of Appendices has been increased from 12 to
17. The Appendix on Atomic Masses and Isotope Abundances has been
expanded to provide tools to aid in determination of elemental
composition from isotope peak intensity ratios. An appendix with
examples on "Steps to follow in the determination of elemental
compositions based on isotope peak intensities" has been added.
Appendices on whether to use GC/MS or LC/MS, third-party software
for use in data analysis, list of information required in reporting
GC/MS data, X+1 and X+2 peak relative intensities based on the
number of atoms of carbon in an ion, and list of available EI mass
spectral databases have been added. Others such as the ones on
derivatization, isotope peak patterns for ions with Cl and/or Br,
terms used in GC and in mass spectrometry, and tips on setting up,
maintaining and troubleshooting a GC/MS system have all been
expanded and updated.
