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 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.

The 600+ is well but there was a small bug!

Rating: 4.7 4.70 Out of 5 Stars

Organization: Shenzhen University

Application Area: Corrosion and Electroanalysis

"There a small bug on your software "Gamry Echem Analyst", which I have reported to your sales staff. However, this problem has always existed. I hope it will be solved as soon as possible. In general, the 600+ works very well. Thanks!"

Industry-leading instrument

Rating: 4.3 4.30 Out of 5 Stars

Organization: ENVOY MEDICAL

Application Area: Analyze medical devices (EIS, voltommetry, etc)

"The instrument gives us what we need--reliable results in a small package. Our instrument is for R&D, so its versatility is crucial. I would like to see other (read: smaller) types of contacts for grabbing and holding very small samples (hence the 4/5 for ease of use) but otherwise, we are happy with the instrument."

Great machine!

Rating: 5.0 5.00 Out of 5 Stars

Organization: Nanjing Forestry University

Application Area: Analyze electrochemical properties of porous carbon materials, we usually test CV, CD, EIS and etc.

"We usually use the machine for testing CV , charging-discharging, or EIS properties of our porous carbon material. It works very well on these tests. the results are reproducible, easy operating, data is good. Also, the service is also good. On many aspects, I like this work station. Two things could be further improved: 1, the fan is noising; 2, the plastic adapters could be firmed."

This equipment gave insights I couldn't get via coupon testing. I use it daily!

Rating: 5.0 5.00 Out of 5 Stars

Organization: Procter & Gamble

Application Area: Corrosion testing.

"Historically we only leveraged coupon testing. I came in contact with the Gamry equipment after a Penn State corrosion short course. I leveraged a nearby corrosion lab to generate some results and concluded a few months later this equipment definitely has the right capability for my needs, of fast and predictive corrosion understanding. The order and set up in our lab went really smoothly and happened in partnership with the vendor over 3 days of training. Following the training the supplier offered a question and answer period of two weeks to ensure all went fine, and I submitted a few questions and received great help. Given the great partnership with the vendor the implementation, ease of use and after sales support turned out to be most successful. I wish I had bought and implemented it earlier."

Great instrument, worth the money
