Overview

Impedance spectroscopy is an extremely powerful non-destructive investigative technique that can obtain essential information about interfacial and bulk material parameters through the use of low energy, time varying electrical excitation. When applied to an electrochemical system, electrochemical impedance spectroscopy (EIS) can provide information on reaction parameters, corrosion rates, oxide characteristics and integrity, surface porosity, coating integrity, mass transport, and many other electrode/interface characteristics. EIS is possibly one of the most powerful methods available in electrochemistry today and is utilized in research and development in essentially every technical sector, e.g., transportation and infrastructure, batteries and fuel cells, medicine, among many others. However, effective utilization of this method has been hindered by the lack of a comprehensive and cohesive explanation of the theory, measurement, and analysis techniques. This course on EIS has been developed to fill this void.

This short course, now in its 26th year, was first taught in 1988 in Charlottesville, Virginia. It has recently had the tremendous fortune of moving to the vibrant and technologically rich city of Houston, Texas. Please read more about our course on this website, or contact us either by e-mail or telephone.

Course Objective

The objective of this short course is to provide a working knowledge of electrochemical impedance spectroscopy. This will include a discussion of the theory of EIS, its application, and most importantly, hands-on laboratory experience. All attendees will use EIS to measure corrosion rates, characterize a metal oxide, examine the effectiveness of a corrosion inhibitor, and determine battery performance. In addition, the attendee will learn methods of data presentation, data interpretation and analysis, and model fitting both in the classroom and in the laboratory. The attendee will become familiar with commercial hardware and software for experimental control, data analysis, and model fitting. Since it is intended for all participants to use the equipment in the laboratory session, the class size is limited to 32 students.

Who Should Attend?

The course is designed for scientists and engineers from industry, government, and academia who have had no prior experience with EIS. However, since the range of information presented is from an introductory to advanced level, this course will also be of interest to those who already have experience with EIS and wish to learn and discuss more advanced topics. An understanding of basic chemistry and physics is requisite, and an understanding of basic electrochemistry will be beneficial.

Course Organizer

Ray Taylor is the EIS course organizer. He is currently a Research Professor within the Texas A&M Engineering Experiment Station and member of the National Corrosion Center, a tri-institutional collaboration between  Texas A&M University, Rice University, and Houston Community College - Southeast College. He has a PhD in materials science and an MS in biomedical engineering with research interests in corrosion, corrosion mitigation, and biomaterials. His broad educational and research background allow him to see many of the common themes that are experienced in interfacial and materials studies.
