Using Squidstats for Stack Measurements on Batteries or Fuel Cells
This application note introduces the differences between using a serial connection versus a parallel connection when using Squidstats to measure interconnected electrochemical systems.
Using Squidstats To Perform Corrosion Testing On a Metal Coupon
Any Squidstat potentiostat can be a very useful tool for quality control testing and to evaluate new material formulations for corrosion protection.
Application Notes & How-To Guides
Introduction to Electrochemical Impedance Spectroscopy (EIS)
EIS is a popular, powerful measurement method that can be used for anything from routine testing to cutting edge R&D of next-generation electrochemical systems.
Calculating Corrosion Rates From a Tafel Plot
Creating and analyzing a Tafel plot is a powerful and time-tested electrochemical testing method to obtain corrosion data and understand corrosion behaviors.
SLIDESHOW - EIS for Advanced Battery Diagnostics
This 16-slide presentation covers key concepts about running EIS on batteries, analyzing the resulting data, and explaining the differences between EIS and traditional DC measurements.
Reconstructing Drift-Affected EIS Data Using the Z-HIT Algorithm
The Z-HIT algorithm, a form of Kramers-Kronig Relations, can be used to prove the stationarity and linearity of a sample undergoing EIS and can use phase shift data to accurately reconstruct the impedance measured at any frequency.
Carrying Out Simultaneous EIS Measurements on Multiple High Current Battery Stacks
This application note is for customers working with multiple high current battery stacks in the range of 400 Ah which require the use of high-current load banks, and parallel EIS measurements using the PAD4 add-on to the Zennium.
Mathematical Introduction to the Normalization of Constant Phase Elements
Modeling EIS data is fundamentally based on mathematically deriving the electrochemical behavior of individual circuit elements, and this application note introduces how to account for non-ideal components within such models.
Why Is The "C" in the Zahner CIMPS Photo-Electrochemistry Workstation So Important?
By directly, continuously, and automatically "C"ontrolling the lightsource intensity of the Zahner "Controlled IMPS" System, users have the unique benefit of eliminating the risk of the light source not performing as calibrated.
Understanding and Validating Potentiostat DC Accuracy
This guide explains the fundamental aspects of defining measurement accuracy, and provides a step-by-step list of instructions for validating the DC accuracy of any potentiostat (not just Squidstats!)
SLIDESHOW - Introduction to Potentiostat Design & Engineering
Anyone who has ever wondered about the electrical engineering aspects of potentiostat design & functionality would be well-served to review this 25-slide presentation.
Using Cyclic Voltammetry To Study Redox Reactions
Cyclic Voltammetry is the defining test method potentiostats are designed to perform. There are several key considerations to understand when running CVs on samples.
