The following choices appear under the EFM Menu: Calculate as Active Selecting this menu choice causes the Corrosion Current, Corrosion Rate, and anodic and cathodic Tafel constants to be recalculated,… read more →
The data file from an Electrochemical Frequency Modulation Trend experiment is normally analyzed by the Electrochemical Frequency Modulation Trend.Gscript data analysis package provided with the EFM software. This script produces… read more →
Loading an Electrochemical Frequency Modulation data file loads the script Electrochemical Frequency Modulation.GScript, which generates the following tabs: EFM Chart This tab shows the I vs. t chart for all… read more →
The Electrochemical Frequency Modulation software uses the Gamry Echem Analyst™ to display, analyze, and print acquired data files. The Gamry Echem Analyst uses Visual Basic for Applications (VBA) as a… read more →
This section describes the standard EFM measurement techniques that are included with the EFM software. Each technique description includes: A short overview of the technique and its uses. A look… read more →
The Electrochemical Frequency Modulation (EFM) software includes experimental scripts and dynamic linked libraries that the Gamry Framework™ software uses. The Framework provides a consistent operator’s interface for the EFM and… read more →
This experiment allows you to follow changes (for up to eight samples) in the corrosion rate versus time. A Gamry ECM8 Multiplexer connects your Gamry potentiostat to each of the… read more →
Many of the parameters are common to all Electrochemical Frequency Modulation experiments, and have been covered elsewhere. The following parameters define each EFM measurement in the EFM Trend. Base Frequency… read more →
