Abstract
The Department Chemistry and Physics at Western Carolina University has added an environmental focus to its curriculum, and gas chromatography-mass spectrometry (GC-MS) was identified as an essential tool in environmental analysis. GC-MS is used in undergraduate chemistry courses in: (i) the identification of synthesized compounds and natural products, (ii) monitoring compounds and their degradation in the environment, and (iii) analytical method development. In Organic Chemistry, the GC-MS is used to characterize natural products and the products of an environmentally benign chemical synthesis. In Environmental Chemistry, the GC-MS is used to identify compounds of environmental interest, such as pesticides in soil samples, polycyclic aromatic hydrocarbons in water, and hydrocarbons in gasoline samples. In Instrumental Analysis I, students characterize numerous compounds in cigarette smoke using GC-MS. In Instrumental Analysis II, students are presented with an analytical chemistry problem for which they research protocols, collect samples, and perform the analyses. The GC-MS has been used to identify volatile compounds in a number of complex mixtures. Also, research in chemistry is a significant part of our curriculum, and numerous undergraduate students have used the GC-MS in their research. The addition of GC-MS has enhanced many of our undergraduate laboratory courses and student-led research projects.
