More Details

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 VoltammetryTechniques such as pulse voltammetry, square wave voltammetry, and associated stripping techniques such as anodic stripping voltammetry.  
  • DC CorrosionRun standard DC corrosion tests such as polarization resistance, potentiodynamic, cyclic polarization, and galvanic corrosion in addition to a number of others.
  • Electrochemical EnergyTest 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 ModulationA 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 Temperaturecontrols a Gamry Potentiostat, TDC4 Temperature Controller, and associated accessories to automatically measure the Critical Pitting Temperature of a material.
  • Electrochemical NoiseA more general form of electrochemical noise testing. It is also an ECM8 Multiplexer compatible electrochemical noise software package. 
  • Electrochemical Impedance Spectroscopyincludes 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 Toolkitcontains 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.

Application Area: Electrochemical corrosion testing

"Ease of use: Use of the software is intuitive and trouble-free. After Sales Care: We have long-term excellent experience with after-sales care from Gamry - e.g. memory extension in an older Reference600 etc. Value for Money: Reference 600+ is highly sensitive and can be applied for very high impedance measurements. As a big advantage I have the option to check the current-potential figure (Lissajousse) during EIS measurements. We have more than 18 experiences with failure-free performance of some of our Gamry potentiostats and we believe Reference600+ will do the same."

"I used the Reference 600 when I first started studying corrosion in university. Now that I have a job at a research institute related to corrosion, I have come to use it again because the Gamry instrument is easy to use and the sensitivity is very good. It's not cheap, but I'm willing to pay for it because it gives good results. I recently made an additional purchase of a Reference 600+. It will continue to be my best friend for my research. Thank you to the engineers and researchers who developed the equipment."

Good, capable and portable potentiostat.

Rating: 4.7 4.70 Out of 5 Stars

Organization: IMRE, A*STAR

Application Area: Electrochemical measurements, batteries, electrocatalysis

"Reference 600+ is reasonably portable, ideal for in-situ experiments. Software is easy to use, although the UI is a bit lacking compared to other brands, for example it couldn't modify your settings on the fly. But, there is an option of customised scripting that expands the experiment possibility if you're willing to invest some time to learn to code. Price is slightly more affordable than other potentiostat with similar capabilities. After sales is reasonable, queries and service request through distributor network is usually prompt, but repairs can take a while if the parts or your hardware need to be shipped to the US."

Application Area: Corrosion tests

"Reference 600+ (+ Softwares and Accessories) Overall + Hardware is very powerful - Softwares (Framework & Echem Analyst) should be improved Pros. + Very satisfying specification (No competitor in Pstat/Gstat/Impedance Analyzer) + Compactness + Electrodes and cells are also satisfying + Basic functions, script, and sequence wizard is very powerful + South Korean vendors (Won-A Tech) are always ready to help Cons. - Relatively expensive compared to other Pstats (But it is reasonable). - Framework & Echem Analyst(EA) need improvements to user interface 1. Setting up save file location is not intuitive. 2. In EA, when I open multiple data, the load data windows always shows designated folder. It should show the latest open folder for better convenience. 3. During EIS analysis, saved equivalent circuits does not appear in a fitting window. 4. Graphical user interface should be improved."
