Gas Chromatograph (GC)

The Gas Chromatograph (GC) (Varian CP 3800 with autosampler) detects the components in a mixture using a flame ionization detector (FID) and thermal conductivity detector (TCD). Analytical Chemistry (CHM 270) students used the GC to assess the amount of ethanol in whiskey, rum, and vodka. In addition, The Chemistry of Perfume (Intersession) nonscience majors ran GC to investigate how well a counterfeit perfume mimicked a designer one. Organic Chemistry II (CHM 170) students also use GC to analyze their alkene products in an alcohol dehydration reaction.
