Python for PalmSens potentiostats - How to get Started + Q&A

This webinar serves as the first installment of a three-part series introducing PyPalmSens, a Python SDK designed for PalmSens potentiostats. Led by host Lutz and software engineer Stef Smeets, the session outlines how to use the SDK to automate experiments, manage hardware, and process electrochemical data.

Python for PalmSens potentiostats - EIS + Circuit Fitting

In this session, electrochemist Lutz Stratmann and software developer Stef Smeets focus entirely on Electrochemical Impedance Spectroscopy (EIS). You will learn the fundamental theory behind EIS and how to configure different measurement modes using our PyPalmSens library. We provide hands-on coding demonstrations for running measurements and performing equivalent circuit fitting with both PyPalmSens and the community-driven impedance.py package. Finally, the video concludes with an extensive Q&A session addressing advanced measurement techniques, data importing, and circuit simulation.
