P92: Vertical integration of gas chromatography-mass spectrometry (GCMS) in the undergraduate chemistry curriculum

Paul Szalay (Muskingum College, USA), Deepa Perera (Muskingum College, USA), Eric Schurter (Muskingum University, USA), Lois Zook-Gerdau (Muskingum College, USA)

GCMS instrumentation was vertically integrated through implementation in six courses; General Chemistry I & II, Organic Chemistry I & II, Analytical Chemistry, and Advanced Laboratory.  These core courses are required of all chemistry majors and are offered every year.  The vertical integration progressed from introductory concepts to increasingly sophisticated use of the instrumental method culminating in student-driven inquiry projects. In General Chemistry students focused on straightforward quantitative and qualitative interpretation of GCMS data.  In Organic Chemistry, students use GCMS to study reaction rates and investigate the effect that altering instrumental parameters can have on the analysis of mixture of compounds.  In Analytical Chemistry, students are required to demonstrate optimized method development skills.  In the Advanced Laboratory course, students demonstrate method development and GCMS utilization in mini self designed research projects.  Details for these experiments will be presented and the progression from introductory concepts to increasingly sophisticated student driven use of the instrument will be highlighted.
