Chromatography is a fundamental component of most analytical chemistry units in undergraduate science programs. Many gas chromatography (GC) and high performance liquid chromatography (HPLC) experiments tend to focus on the quantitative aspect of the technique (determination of benzoic acid in coca cola or ethanol in wine) However, these experiments do not actively develop students understanding of the separation processes involved and method development (i.e. development of best separation conditions) is limited due to time constraints. To address these issues we have been active in developing experiments that promote understanding of the separation mechanisms involved
