The Center for Electroanalytical Studies

"We're Changing the World One Electron at a Time"...

Mission StatementElectroanalytical Logo

The Center for Electroanalytical Studies is dedicated to providing valuable research experience to undergraduate students by developing electrochemical methodologies that serve the region.


History of the Center for Electroanalytical Studies

The Center for Electroanalytical Studies began at Southwest Minnesota State University (SMSU) in August 1997. Home-made equipment was used to conduct our first experiments involving the polarography of copper, iron, and cadmium. 

Our home-made equipment was modified so it could be used for stripping voltammetry of lead. This work was presented by the group at the 1998 Spring National Meeting of the American Chemical Society (ACS) held in Anaheim, CA.

We purchased our first commercial instrument using Minnesota Higher Education Preservation and Renewal (HEPR) funds allocated in 1999 and began a lead-testing outreach program with area secondary schools. This work resulted in a publication in the Journal of Chemical Education in 2004 and a presentation at Purdue University in 2006.

The group obtained a grant from the Minnesota Center for Teaching and Learning (CTL) in 2003. We purchased a more sophisticated instrument and began analyzing the electrochemical properties of herbicides. This research resulted in two publications in the Journal of Electroanalytical Chemistry.

Our electrochemistry research is currently supported by the Minnesota Center for Teaching and Learning (CTL), Southwest Minnesota State University (SMSU) Foundation, and the Faculty Improvement Grant (FIG) committee. Additional sources of fund are:

  • Higher Education Asset Preservation and Renewal (HEAPR)
  • American Recovery and Reinvestment Act (ARRA)
  • National Science Foundation (NSF) – Grantee Robert Eliason

Contributions for additional funding are welcome. For more information of ways help support our research contact the SMSU Foundation to learn more about Ways to Give. Or, you may contact the SMSU Foundation at 1-800-260-0970 or We are thankful for any support received. 

Current Research Focus

To determine the electrochemical properties responsible for the biological activity of triazine herbicides. The purpose of the work is to determine structural changes to produce more effective herbicides. Projects include:

  • Differential pulse voltammetry of simazine and cyanazine.
  • Computer modeling of the triazine herbicide reduction process.
  • The study of herbicide adsorption on the electrode surface.
  • Extraction and analysis of herbicide metabolites from plant materials.
