The Chemistry Department at the College of Saint Benedict/St. John's University has 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 both laboratories, students purify a set of unknowns via prescribed methods and then analyze them through NMR, IR and UV spectroscopy, mass spectrometry, and gel electrophoresis.   This presentation will focus on the implementation and assessment of these two laboratories.
