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.
This application note introduces the differences between using a serial connection versus a parallel connection when studying fuel cell or battery stacks.
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.
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
The clicking is simply an indication that the potentiostat is capable of operating across a wide range of current measurements without interruption.
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.
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.
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.
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.
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.
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.
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.
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.
In this guide, we explain how to configure two Squidstat channels as a bipotentiostat for Rotating Ring Disk Electrode (RRDE) experiments.
Frequently Asked Questions
How is raw data collected by the Squidstats formatted, and can it be exported into data analysis programs?
All Squidstats have raw data saved into a .csv file that can be easily exported into other programs for more advanced analysis. Our advantage over most other potentiostats is that all data collected while any Squidstat channel is running is continuously recorded and automatically saved into the .csv file. Users are not required to save their data any time after a channel has started running. This means that in the event of a loss of power to the Squidstat or a similar issue, the data collected during the experiment can be retrieved up to the point of power loss. Better yet, if there is a computer crash or loss of power, but power is still available on the Squidstat, the experiment that was already running at the time of computer failure will still continue uninterrupted on the Squidstat.
Can data from two or more channels be plotted within a single graphing window? And can old data be overlaid with new data currently being collected?
Yes, our graphing tools allow for practically any number of separately collected datasets to be displayed on one graph. There is also an option to display a primary and secondary y-axis.
What electrical certification markings do your Squidstats conform to (UL, CE, CSA, etc.)?
All Squidstats conform to CE certification 2006/95/EC for electrical devices. We have the ability to have CSA certification applied to any individual Squidstat through the CSA Field Labeling program. We do not have plans to apply for other forms of certification markings right now, but if your lab requires equipment to conform to additional standards beyond CE or CSA please contact us and we can try to make arrangements for you.
What is Admiral Instruments' policy about discounts on the Squidstat listed pricing?
We firmly believe in offering all customers excellent value upfront, and do not want to force anyone to go through the awkward process of requesting a discount just to get a fair deal. Unlike most other potentiostat companies, we openly disclose Squidstat pricing on our website so you know exactly what to expect. We do this because we know we offer very competitive pricing when considering the capabilities of our Squidstats versus similarly-equipped systems. Taking our production costs into account, it’s challenging for us to offer discounts to customers ordering just a single Squidstat at a time.
What are Admiral Instruments' product return and warranty terms?
All customers have a 30 day window after delivery of their Squidstat to return it for a full refund. During this 30 day period, customers may ask to return products for a refund for any reason. After 30 days, customers are covered by our 2-year warranty for repairs or replacements but will no longer be eligible for refunds.
