Our Support Team is Fully Devoted to Making Your Job Easier!

Unlimited Technical Support Freely Available by Phone and Email

Admiral Instruments is always ready and willing to answer questions from anyone, whether you are an existing customer or if you use potentiostats from other companies. We love to brainstorm creative ways to run experiments.


This page contains resources to help answer questions about how to operate our Squidstats, Zennium Workstations, and more.


For in-person support, please contact us to discuss available options or to schedule an individual appointment at an upcoming conference Admiral Instruments plans to attend.

Overview About Using Squidstats for Stack Measurements on Fuel Cells or Batteries

This application note introduces the differences between using a serial connection versus a parallel connection when studying fuel cell or battery stacks.

Are Squidstats Capable of Both Grounded and Floating Measurements?

This guide covers options for grounded and floating measurements, and explains the multichannel grounding configuration in different Squidstat models so users can know how to avoid creating ground loops.

Using Squidstats To Carry Out Corrosion Testing of 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

Why Do Potentiostats Click?

The clicking is simply an indication that the potentiostat is capable of operating across a wide range of current measurements without interruption.

Brief Introduction to Electrochemical Impedance Spectroscopy (EIS)

EIS is very popular because it’s a powerful 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

Analyzing a Tafel plot is a comprehensive and time-tested method to obtain corrosion data using electrochemical methods, and any Squidstat potentiostat is well-suited to obtain the raw data necessary to do so.

Can I Operate More Than One Squidstat in a Multichannel Configuration?

Users can connect single-channel or multichannel Squidstat modules together on a single computer for multichannel functionality, and there are options to control over 1,000 channels simultaneously and independently.

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.

Drift in Battery Measurements - A Phenomenon of Daily Life

This application note demonstrates several examples of battery and fuel cell measurements that are impacted by drift effects during EIS, and showcases how to correct for these effects using the Z-HIT algorithm.

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.

Can Squidstat Potentiostats Be Configured as Bipotentiostats for RRDE?

In this guide, we explain how to configure two Squidstat channels as a bipotentiostat for Rotating Ring Disk Electrode (RRDE) experiments.
