Gas chromatography is a sophisticated tool for the isolation, identification and quantification of chemical compounds. The purpose of this exercise is to introduce the principles of gas chromatography to first year chemistry students. For the exercise, students inject their own chemical samples, estimate the purity of these samples by counting the number of peaks on a print out, measure retention times for the materials observed, and compare the "r" values to those of known substances.
