The target samples will be one of several types. Solid phase microextraction will be employed for sampling. The qualitative composition of two or three different samples will be evaluated using total ion abundance chromatograms, mass spectral fragmentation patterns, and mass spectral library matching.
Mass spectrometry is particularly advantageous for the analysis of complex samples.
In terms of versatility, selectivity, sensitivity, and information content, MS is the detector of choice for or many GC applications. The complexity and cost of benchtop instruments has decreased in recent years, making mass spectrometry more accessible for chromatographers. The mass spectrum of a compound is often sufficient for chemical identification. Even if the mass spectrum cannot be fully interpreted or matched to a library spectrum or to the spectrum of an authentic standard, characteristic fragmentation patterns and masses often suggest structural features. Although sample preparation is often required, the instrumental measurement of a mass spectrum is rapid.
