Dino Klotz

Dino Klotz was an Application Scientist at Zurich Instruments until January 2023. He started working with impedance spectroscopy during his PhD in Karlsruhe and since then has applied his knowledge for renewable energy applications in Germany, Japan, Israel and the USA. At Zurich Instruments, he enjoyed sharing this knowledge and helping researchers with their challenges related to impedance measurements. Tennis, skiing, windsurfing and cycling are other passions that he likes to pursue.

Choosing Between 2-Terminal and 4-Terminal Impedance Measurements

31.01.2023

The MFIA is a high-precision impedance analyzer that can run measurements in either 2-terminal or 4-terminal mode. What is the right setting for your measurement? This blog post addresses this question and explains how to use the MFIA to its full capability...

Electrochemical Impedance Spectroscopy Beyond 300 GΩ

19.01.2023

In electrochemistry, the characteristics of a given process can be assessed by electrochemical impedance spectroscopy (EIS). A semicircle in the Nyquist plot usually corresponds to electrochemical processes that can be modelled as a parallel connection of a resistor (R) and a capacitor (C). The diameter of the semicircle provides the value of R, while the associated time constant (also known as relaxation time) is given by RC...

Setup for measuring grounded components with the MFIA

The MFIA is a high-precision impedance analyzer. It measures voltage, current and phase to calculate impedance. As is the case for most impedance analyzers, the measurement circuit is designed so that the device under test (DUT) is operated under floating conditions, which means that none of the terminals of the DUT is connected to the ground...

Dino holding the MFIA and the April issue of Nature Materials

This blog post summarizes the latest academic project of Dino, our new Application Scientist Impedance Analysis. He investigated materials for high-temperature fuel cells in Fukuoka, Japan and the results made it to the front cover of Nature Materials. Learn how light can be used to increase the ionic conductivity of standard electrolyte materials for solid oxide fuel cells, and how to measure this effect using the MFIA Impedance Analyzer.
