Exposure to real-life applications of quantitative analysis techniques based on two gas chromatography (GC) experiments was provided to a large cohort of sophomore-level students. In one experiment, students assessed blood alcohol content by internal standardization using a homemade headspace system similar to methods implemented in forensic laboratories. In a second GC experiment, students found the amount of an odorous terpene present in store-bought essential oils through the technique of standard additions. Students learned the importance of standardization techniques, sample handling, and the use of chromatography in modern analytical applications.
