The new Reference 600 - the Reference 600+ is a high-performance potentiostat/galvanostat/ZRA particularly suitable for applications in physical electrochemistry, sensors, coatings, and corrosion.
OverviewThe Reference 600+ is a high-performance, research-grade potentiostat/galvanostat/ZRA designed for fast, low-current measurements. It does well for a variety of applications such as physical electrochemistry (especially at microelectrodes), fast cyclic voltammetry, electrochemical corrosion, electrochemical noise measurements, paints and coatings, and sensors. It has a number of auxiliary input and outputs designed to help you interface or control ancillary equipment such as a rotating disc electrode. It also has a thermocouple input for temperature measurements.
Electrochemical Impedance SpectroscopyThe Reference 600+ comes fully equipped to perform electrochemical impedance spectroscopy. The Accuracy Contour Plot shown below provides a detailed look at the performance you can expect from your instrument in real-world situations. The results include the cell cable.
- Extended Cable Lengths
- Extended length cell cables (1.5 m, 3 m, 10 m) are also available for your convenience.
Below are additional details regarding the capabilities of the Reference 600+ potentiostat. Each bullet point contains a list of the type of techniques available for the instrument to run.
- 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 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 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.
- 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.
- eChemDC Toolkit - contains all of the capabilities of the eChemBasic and further extends these capabilities by adding advanced signals and data acquisition modes to simplify implementing experiments like cyclic voltammetry, pulse voltammetry, and dynamic DC corrosion techniques. Also includes more advanced stop tests, particularly useful in fast experiments.
- eChemAC - Includes full capabilities of eChemDC Toolkit plus allows electrochemical impedance spectroscopy (EIS) and EFM experiments.
