Should I choose "vs. Eref" or "vs. Eoc" for EIS on coatings?

Posted by Aaron on 14 September 2012

EIS logo2We have seen several examples where a customer has recorded an open circuit voltage of 3, 4, or even 5 volts when running EIS on a coated sample.  The Eoc values that were recorded in these experiments are probably not real Eoc readings.  For very, very good coatings, such as the ones that these researchers were studying, we recommended that the potentiostatic EIS measurement be done at a potential vs. Eref, not vs. Eoc. The Eoc values are often not related to the coating or to the substrate: They are a function of the length of time the potentiostat has been connected to the cell.

How do I copy and paste graphs and data from Echem Analyst?

Posted by Aaron on 14 September 2012

The “Copy to clipboard” button is located on the toolbar of the Chart tab when your data file is displayed in Echem Analyst.  This button gives you the option to copy a Bitmap, Metafile, or raw data directly to the Windows Clipboard.  It can then be pasted into any other program.  The Bitmap option will copy the data as displayed in Echem Analyst, meaning that it will be a replica of the current view of the data complete with any overlays, fits, or modifications of the visual style of the plot.  Using the “As Text (data only)” button will copy the X and Y values of the currently displayed data, fits, and overlays as a table that can be directly pasted into a cell-based spreadsheet application.  By overlaying multiple data files you can use the Copy As Text feature to batch-export a number of data files in one fell swoop.

Vac too small

Posted on 28 July 2011

EIS logo2There are several possible reasons that this message will appear during an EIS scan. The first thing to check is that all of your cell connections are appropriate. If the error continues to appear one should run a full calibration of the system. During the calibration the performance of the EIS components are checked. Depending on the results of the calibration, we can determine if the problem may be cable related or if a repair of the instrument is required. Please email your Calibration Results file (generated during calibration and stored as a .txt file in the My Gamry Data folder) to Gamry by using the Technical Support Form.
