The Interface 5000E potentiostat is designed for cell-level testing of various energy storage and conversion devices and includes capabilities for monitoring both half cell voltages in addition to the whole cell voltage during an experiment.
A second electrometer gives you the ability to monitor both half cells in a typical three electrode setup. You can monitor both the anode and cathode in addition to the entire cell in charge/discharge experiments and EIS experiments.
Accuracy Contour Plot
The accuracy contour plot provides a detailed look at the performance you can expect from your instrument in real-world situations. The results include the cell cable. Accuracy contour plots are important because they let you compare the performance of different manufacturers to ensure you are getting the best possible measurement.
The Interface 5000E can be configured as a single-channel potentiostat, bipotentiostat, or multichannel-potentiostat providing you with the flexibility you need to get more done.
Below are additional details regarding the capabilities of the Interface 5000E potentiostat. Each bullet point contains a list of the type of techniques available for the instrument to run.
Electrochemical Energy – Test single-cells and stacks of various batteries, fuel cells or supercapacitors. Includes charge, discharge, cyclic charge-discharge techniques, potentiostatic, galvanostatic, self-discharge, leakage rate, and read cell voltage.
Electrochemical Impedance Spectroscopy – Includes experimental scripts for potentiostatic, galvanostatic and hybrid impedance spectroscopy experiments in addition to single frequency techniques like Mott-Schottky. We also have our unique power-leveling multisine technique that improves signal-to-noise across the spectrum. On the analysis side, it provides tools for fitting spectra to equivalent circuit models, Kramers-Kronig transform for data validation and a graphical model editor. Our software even includes a script for EIS simulation.
Physical Electrochemistry – Techniques such as cyclic voltammetry, chronoamperometry, and chronopotentiometry and derivatives of these techniques.
Pulse Voltammetry – Techniques such as pulse voltammetry, square wave voltammetry, and associated stripping techniques such as anodic stripping voltammetry.
DC Corrosion – Run standard DC corrosion tests such as polarization resistance, potentiodynamic, cyclic polarization, and galvanic corrosion in addition to a number of others.
Electrochemical Signal Analyzer – Designed specifically for the acquisition and analysis of time-dependent electrochemical noise signals. Cell voltage and current are continuously monitored at rates from 0.1 Hz to 1 kHz. A full featured set of analysis tools provides powerful analysis features such as statistical analysis, detrending, impedance spectra, and histogram analysis.
Electrochemical Frequency Modulation – A non-destructive corrosion rate measurement technique. It allows for measurement of the corrosion rate without prior knowledge of the Tafel constants. In addition, the technique determines the Tafel constants and provides 2 internal validity checks.
Critical Pitting Temperature – Controls a Gamry Potentiostat, TDC4 Temperature Controller, and associated accessories to automatically measure the Critical Pitting Temperature of a material.
Electrochemical Noise – A more general form of electrochemical noise testing. It is also an ECM8 Multiplexer compatible electrochemical noise software package.
eChemAC Toolkit – Software toolkit that gives full control of a potentiostat capabilitieselectrochemical impedance (EIS) measurements and EFM experiments.
