Framework creates a runner window, and the GetRu.Exp script runs in this window. The script creates the Setup dialog box, which becomes the active window and accepts changes in the… read more →
Click on each of the setup parameters for a description of its use and function. Pstat Selects the potentiostat/galvanostat that will perform the experiment. Each labeled button corresponds to an… read more →
Electrochemical test cells always have a solution resistance controlled by the cell’s geometry and the composition of the cell’s electrolyte. Current flow through this solution resistance can cause significant errors… read more →
Open Circuit Potential is used to measure the open-circuit voltage (Eoc) of an electrochemical cell. It can be run on all Framework™ systems that include a Gamry Instruments potentiostat. NOTE:… read more →
The Utilities menu includes a number of general-purpose routines that perform the following functions: Potentiostat Calibration to correct for drifts in instrument circuits. Menu selections are: Calibrate Instrument DC Low… read more →
Set a Current is used to apply a current to an electrochemical cell and measure the voltage resulting from that current. It creates a graph of voltage versus time with… read more →

Stray Elements as a Source of EIS Errors EIS measures the impedance of an electrochemical cell over a wide range of frequencies. Often EIS measurements suffer from errors caused by… read more →
Select Experiment >Utilities >Calibrate Instrument on the Framework menu. You see a dialog box similar to this: This Framework system has two Gamry potentiostats connected: a Reference™ 600+ and an… read more →
Compliance Voltage is used to change the maximum voltage output of a Reference™ 3000 potentiostat. Compliance voltage is the maximum voltage that can be applied between the counter electrode and… read more →
