Characterization of Complex Organic Mixtures

Overview

This activity was prepared by David Walker (LASA High School) and Rose Cory (University of Michigan), based on work conducted at Toolik Field Station in Alaska. The purpose is to introduce students to Van Krevelen diagrams, which are used to interpret results of high resolution mass spectrometry and characterize the compound classes present in complex organic mixtures. Students will
