Distribution of Relaxation Times (DRT)
DRT analysis has been available for a while now in Echem Analyst 2. As a complementary method to the traditional equivalent circuit modeling, DRT analysis transforms impedance data into a curve with peaks that are associated with RC time constants—hence its namesake. To a first approximation, one may use the number of peaks in the DRT to build a more informed equivalent circuit. However, there are nuances to this approach. That’s why we’re hosting a live webinar that focuses solely on the DRT itself and how to tell if the output is correct.
DRT analysis is useful in systems where many interfacial impedances are expected, such as in batteries, fuel cells, electrolyzers, and other multi-layered electrochemical devices. For a snapshot of how DRT analysis is used, check out our application note, "EIS and subsequent DRT characterization of a vanadium redox-flow single cell".
Join us on October 8th 10:00 AM ET for a Live Webinar "A User’s Guide to the Distribution of Relaxation Times" Presented by Jake Huang from Institute of Inorganic and Analytical Chemistry University of Münster.
