Essential handbook for all analytical scientists and laboratories using GC-MS covering both
the fundamental and practical aspects of this analytical technique From essentials to
applications Handbook of GC-MS:Fundamentals and Applications is a comprehensive reference and
training compendium on the popular and evolving technique of GC-MS (gas chromatography mass
spectrometry) guiding readers through the most used sample preparation methods for GC-MS and
method development with many practical indications supporting the design of optimized analyses
and providing practical approaches to data processing compound identification and
quantification. The text details both a solid background and principles of operation as well
as a broad range of current real-life examples taken from laboratories in environmental food
pharmaceutical and forensic analysis. It also features a glossary of more than 300 terms and
a comprehensive substance index that facilitates finding a specific application. This timely
Fourth Edition covers the latest developments in automated sample preparation techniques and
instrumentation also with the focus on Green Analytical Chemistry. This comprehensive handbook
presents GC-MS applications in various fields with coverage of the well-known QuEChERS
pesticide extraction solid phase extraction and solid phase microextraction static and
dynamic headspace analysis liquid liquid extraction outgassing and thermal desorption
including pyrolysis. Single and triple quadrupole Orbitrap time-of-flight magnetic sector
ion mobility and isotope ratio MS are discussed with their advantages and limitations. Sample
topics covered in Handbook of GC-MS: Fundamentals and Applications include: Sample inlet
systems for hot needle liquid band injection with large volume and LC-GC application carrier
gas saving choice of columns septa and injection port liners Optimization of the GC method
with carrier gas flow effect of oven temperature ramp rates fast GC and multi-dimensional
gas chromatography Ionization processes electron and chemical ionization resolution power in
mass spectrometry reading and interpreting mass spectra Extraction of mass spectra manual
spectrum subtraction deconvolution of mass spectra retention index and library search of
mass spectra Typical mass spectra of common analyte groups like pesticides persistent organic
pollutants drugs explosives and of frequently occurring impurities Quantification using
external and internal standards and standard addition methods. Determination of the limits of
detection and quantitation. Applications covering food water flavor and fragrance
metabolomics forensic and material analysis The Handbook of GC-MS: Fundamentals and
Applications is an essential reference for the daily GC-MS practice and application of new
methods. It serves as an excellent introduction for newcomers as well as an educational
resource about this analytical technique. Analytical chemists chromatographers environmental
chemists food chemists and pharmaceutical chemists will find it of high practical use.
