We describe a novel experiment for high school students that uses gas chromatography (GC) equipment to demonstrate the principles of chemical quantitation in the context of fragrant compounds. A highlight of the work is the use of inexpensive equipment and tools accessible to the usual high school laboratory. The students use control samples, learn about functional groups and chemical separations, and are introduced to a commonly used chemistry instrument. We describe the protocols in detail and analyze student survey results to highlight the advantages of this experiment as well as possible routes for further improvement.
