Gamry Advantages

Researchers looking at high throughput or materials selection are looking for easy-to-use, reliable systems, that give them the right answer.  Gamry has long been known as the market leader when it comes to instrumentation for corrosion testing.  Running ASTM testing is easy with our standard list of experiments – Polarization Resistance, Potentiodynamic, Cyclic Polarization, etc.  Our Sequence Wizard lets you string together experiments, click Start, and then come back when finished.

All of Gamry potentiostats are electrically isolated, allowing you to run experiments on grounded cells such as autoclaves.  High compliance voltages ensure adequate power when dealing with resistive electrolytes. 

Our analysis software allows for easy data workup, reporting and charting.  Easily compare results or export data for workup in another program.

Gamry Expertise

Gamry Instruments has been producing lower cost, electrically isolated potentiostats for corrosion testing since 1989. We have the most comprehensive electrochemical corrosion technique library around, including Gamry developed/exclusive experiments.

We are also very willing to share our expertise with our customers. There are Applications Notes which are relevant to corrosion scientists and engineers. We also have electrochemistry specialists available over email or phone that understand corrosion testing, and can get you pointed in the right direction.

If you are new to corrosion research and electrochemical corrosion testing in particular, you may want to start with a quick look at our Application Note on DC Corrosion Techniques, and consider enrolling in a short course like the one taught at Pennsylvania State University every summer. For those who are already familiar with the corrosion process, please have a look at our Application Notes covering Electrochemical Impedance Spectroscopy, and consider swapping your Rp/Ec Trend out with EFM Trend.

Recommended

Recommended Systems:

Routine ASTM G 59, G 61, F 746, or F 2129 Testing - Interface 1000A1000E or 5000E (single or multichannel setups depending on throughput needs), Multiport, two Saturated Calomel Reference electrodes (one as a backup).  Gamry recommends the ECM8 Electrochemical Multiplexer if increased throughput at a lower price point is necessary. Note that the multiplexer runs experiments sequentially, not simultaneously. For very corrosion resistant systems (very low corrosion rates), Gamry recommends the Reference 600+ due to its low-current (60 pA lowest full-scale range) capabilities. 

If you are considering doing electrochemical impedance experiments, the Interface 1000E, Reference 600+, Reference 3000, and Reference 3000AE are all ideal instruments.  

Critical Pitting Temperature - Any of the above-mentioned instruments can perform critical pitting temperature experiments but you will also need a TDC4 temperature controller (or equivalent), FlexCell, heating mantle, stirring motor, and stirring rod kit.
