Author & Objectives

This module provides an introduction to Atomic Absorption Spectroscopy (AAS).  AAS is a broad area that includes several analytical chemistry techniques focused on elemental analysis, the identification, quantification, and (sometimes) speciation of the elemental makeup of a sample.  AAS can be an extremely useful tool and is utilized in academic and industrial settings within biological and chemical sciences.  It is mainly used in quantitative analysis, but can be used in qualitative work as well.  Atomic Emission Spectroscopy is a complementary technique can be used and a corresponding learning module supporting this it can be found here.  Note that when appropriate, the AES module material is directly ported here — thanks to the authors for making it available for use.


  1. Give an introduction to atomic absorption spectroscopy.
  2. Make the module useful for whatever depth of learning desired.
  3. Allow for interactive learning via hovering or problems.
  4. Allow for others to build from this module and incorporate it into their modules.
