How to correct impedance measurements when using longer cables or a test fixture
Focus on your Device under Test. How to remove parasitic impedance due to extension cables or connection interfaces
The different current and voltage setpoint options in EC/BT-Lab®
This article presents the various options available in EC/BT-Lab® for potential and current setpoints.
Scanning probe electrochemistry for sustainable energy research
A short article and associated video relating to scanning probe electrochemistry and sustainable energy
How to use EIS accuracy contour plots
EIS accuracy contour plots must be used to interpret errors made during EIS measurements and identify the best frequencies possible for a given impedance range.
Effect of the staircase on current sampling.
An article detailing the effect of the staircase on current sampling
Checking and validating reference electrodes
The reference electrode is part of the 3-electrode setup. A bad reference electrode can impact negatively on measurements. In this article, we discuss the protocol necessary to check reference electrodes.
Investigation of impedance measurements using the Z Sim tool
To adjust the frequency range of your EIS experiment or just to see the shape of your model, Z Sim is available on both EC-Lab® and BT-Lab® software.
How do I customize my plots?
A suitable plot with the right variables allows you directly access the results and saves a great deal of time during the analysis. In this short article we show you how...
Create and save your own protocols
Learn how to save time by configuring full experiments from previous settings; including safety limits, advanced settings, cell characteristics and external device configuration.
Split an EIS experiment into multiple sequences: save time without compromising measurement quality
Reliable impedance measurements require the system under study to remain linear and stationary during the whole measurement sequence. This article describes the ideal configuration for studying unstable systems such as batteries or supercaps to save time while maintaining good measurement quality.
Anode, cathode, positive and negative: battery basics
This article clarifies the differences between anodes cathodes and positive and negative electrodes in secondary batteries.
Cyclic Voltammetry: how to obtain great results with your potentiostat
What are the critical Cyclic Voltammetry parameters and how should you tune them correctly to ensure you get the best out of your instrument?
Coupling potentiostats & spectrometers for spectroelectrochemical measurements
One of the possibilities of characterizing intermediate species created during a redox process, is to couple a spectrometer with a potentiostat
What is EIS ?
Electrochemical Impedance spectroscopy (EIS) is a powerful tool enabling the study of processes that occur at the interface of the electrode.
Data of interest – work more efficiently.
Get the most out of your potentiostat/battery cycler : how EC/BT-Lab can help you work more efficiently as well as save valuable time.
Resolution, Precision, Accuracy, Temperature stability and Time base: The five to watch
The five characteristics that should be on every electrochemist’s radar
No need to plan your future analysis… Go straight ahead
It is time to demystify a false truth. You really do not always need to add points in the record settings of BT-Lab® and EC-Lab® in order to obtain highly accurate measurements.
Modify on-the-Fly: Flexible potentiostat/battery cycler control
No need to stop the experiment with EC-Lab®’s “modify-on-the-fly” functionality
Why 4-point measurements?
A potentiostat / galvanostat is an instrument that can control both the current and the voltage imposed to a cell. For this purpose, Bio-Logic instruments require at least 4 cables:
Potentiostats: Obtaining high quality measurements…
This article gives some tips to improve the quality of measurements, from optimizing the setup or the connection interfaces, to the geometry of the cell itself.
