Nano‐Impact Electrochemistry: Effects of Electronic Filtering on Peak Height, Duration, and Area

Invited for this month's cover picture is the group of Prof. Dr. Kristina Tschulik from Ruhr University Bochum (Germany). The cover picture shows the alteration of a current signal caused by the electronic filtering implemented in potentiostats. These filter effects are uncovered and a simple method is provided for electrochemists to test and validate their experimental setup. This is particularly important for transient single‐entity electrochemistry, which requires low current measurements at high time resolution.

The accurate measurement of nano‐impact signals is crucial to obtain reliable coulometric and mechanistic information from particle collision experiments. It is demonstrated that the signals are often significantly modified by electronic filters in potentiostats. This could result in inaccuracy and misinterpretation of the results. Therefore, a simple method is provided for researchers to test and validate their experimental setup…” Find out more about the story behind the front cover research at 10.1002/celc.201800738.
