We are students in the Instrumental Analysis course taught by Dr. Tom Spudich at Maryville University in St. Louis, Missouri. As part of our course curriculum, we endeavored to create a comprehensive online learning module for Atomic Absorption Spectroscopy (AAS) in order for students everywhere to gain an understanding of this analytic method. With the gracious collaboration of many individuals and institutions (please see our References page), we feel we’ve been able to provide a reasonably thorough context by which to explore the principles and methodologies associated with AAS. We are, however, always aware that technologies and practices are constantly evolving, and we welcome any suggestions that would enhance the quality of our site. Please feel free to share your thoughts with us by navigating to our Contact Us page.
