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 →
Most of the parameters for Multiplexed EFM Trend are common to all Electrochemical Frequency Modulation experiments, and they are already covered under those experiments’ Help topics. The real difference between… 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 →
Run the Multiplexed EFM Trend technique by selecting Experiment>Electrochemical Frequency Modulation>Multiplexed EFM Trend from the Framework™ menu bar. This initiates the following sequence of events: Framework creates a runner window,… read more →
Definitions of Key Words The following key terms are used throughout this help section. Active Cell The cell (if any) currently connected to the system potentiostat. Any electrochemical measurements are… 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 →
This experiment allows you to follow changes in the corrosion rate of a sample versus time. The Electrochemical Frequency Modulation Trend script makes a series of EFM measurements at fixed… read more →
Run the Electrochemical Frequency Modulation Trend standard technique by selecting Experiment>Electrochemical Frequency Modulation>Electrochemical Frequency Modulation Trend from the Framework™ menu bar. This initiates the following sequence of events: Framework creates… read more →
A single Electrochemical Frequency Modulation experiment makes a rapid measurement of the corrosion rate of a sample without a priori knowledge of Tafel constants. You may also wish to run… read more →
