ELECTROCHEMICAL IMPEDANCE
SPECTROSCOPY
Theory, Applications, and Laboratory Instruction
A Short Course: November 1-5, 2009 in Houston,
Texas
 The
2009 EIS Short Course will be held in Houston, TX on November 1-5, 2009. The
Faculty for this Short Course comes from the University of Texas Health
Science Center, Ohio State University, Rockwell Science Center, and
Battery Design Company. The topics range from corrosion to batteries
and fuel cells, and nearly everything in between.
Although the lectures provide a great background in EIS,
the real learning seems to come in the lab sessions. There's plenty of
opportunity for one-on-one contact with the course faculty, as well as
student-to-student sharing.
 Dr.
David Loveday of Gamry will be there to answer questions about Gamry
instrumentation and electrochemistry in general.

Course Overview
Impedance spectroscopy is an extremely powerful
experimental technique that compares the electrical response of a test
system to a time varying electrical excitation to delineate interfacial
and bulk material parameters. When applied to an electro-chemical system,
impedance spectroscopy can provide information on reaction parameters,
corrosion rates, oxide integrity, surface porosity, coating integrity,
inhibitor function, mass transport, and many other electrode/interface
characteristics. However, effective utilization of this spectroscopy
technique has been hindered by the lack of a comprehensive and cohesive
explanation of the theory, measurement, and analysis techniques.
This course has been designed to fill this void.
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, applications, and measurement methods.
A key objective of this course is to provide hands-on laboratory
experience. The attendee will use EIS to measure corrosion rates and
battery performance, and will learn methods of impedance data analysis,
interpretation, and model fitting both in the classroom and in the
laboratory. The student will become familiar with major brands of
commercially available impedance systems as well as with software for
experiment control, data analysis, and model fitting. Since it is intended
for all participants to use the equipment in the laboratory sessions, the
class size will be limited to 30 students.
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 discuss more
advanced topics. An understanding of basic chemistry and physics is
requisite, and an understanding of basic electrochemistry will be
beneficial.
