At the College of Saint Benedict/St. John's University, we have received NSF funding to fully revise our first year laboratory sequence. These foundation labs introduce students to the laboratory through the practice of purification techniques. The first semester course (Purification 1) focuses on methods such as distillation, filtration and extraction, whereas the second semester laboratory (Purification 2) introduces a wide variety of chromatographic techniques. In Purification 1, students purify a set of unknowns via prescribed methods and then analyze them, primarily using NMR and IR techniques. This presentation will focus on lessons learned from the development and implementation of the first semester of Purification 1 Laboratory.
