In addition to normal chronoamperometric tests, the Raman Chronoamperometry experiment allows you to perform chronoamperometric and spectroscopic measurements simultaneously.
The Spectroscopy help section covers mainly definitions, parameters, and commands for the spectroscopic part. For information about setup parameters and commands for corresponding electrochemical experiments, see the Physical Electrochemistry help section.
The main Raman Chronoamperometry window is
If you activate the Advanced Spec. Setup checkbox, an Advanced Raman Spectrometer Setup window appears:
Parameters for these two windows are:
|Laser Power (%)||see Raman Spectroscopy|
|Advanced Spec. Setup||Opens Advanced Raman Spectrometer Setup window for additional Raman settings, if enabled.|
|Integration Time||see Raman Spectroscopy|
|Min Wavenumber||see Raman Spectroscopy|
|Max Wavenumber||see Raman Spectroscopy|
See Chronoamperometry experiment for all other parameters
Run the Raman Chronoamperometry standard technique by selecting the Named Script command under the Experiment menu in Gamry’s Framework™. Opening the Raman Chronoamperometry.exp file initiates the following sequence of events:
a. If you click the OK button, theAcquire Dark Spectrum window appears.
By clicking OK again, a dark spectrum is recorded. The data of the dark spectrum are not saved. The Acquire Blank Spectrum window appears.
By clicking OK, a blank spectrum is recorded. The data of the blank spectrum are not saved. ARuntime Warning appears.
By clicking OK the actual measurement starts. The previously measured dark and blank spectra are automatically subtracted.
b. If you click the Cancel button, no dark or blank spectra are recorded. For the actual measurement, Raw Counts are measured and plotted versus wavenumber.
