Understanding Mass Spectra, A Basic Approach, Second Edition (R. Martin Smith)  Bill Boggess
The interpretation of mass spectra represents arguably the most significant challenge to both newcomers and practitioners in the field of mass spectrometry (MS). For those of us who have ever struggled to use a mass spectrum to solve the structure of an organic compound, R. Martin Smith offers the second edition of Understanding Mass Spectra, A Basic Approach. Fortunately, the author manages to go well beyond the obvious and expected explanations of the common modes of fragmentation for ions generated during electron ionization (EI) by offering a rational approach to mass spectral problem solving. This ten-step approach, which represents the most important contribution of this text, appears in chapter 5 and is condensed into table 5.1.

Antacids Revisited with Modern Chemical Instruments: GCMS, AAS, and CCT  Stanley L. Burden and Christopher J. Petzold
This paper describes a novel experiment that requires students to obtain and interpret data from several analytical techniques to identify the brand name of a commercial antacid. They are required to design a set of experiments utilizing computer controlled titrations (CCT), atomic absorption (AA), gas chromatography-mass spectroscopy (GCMS), and careful quantitative manual titrations using a visual indicator of their choice to determine the brand name of their sample from a list of six to eight choices.
