Technique Command

Use this command to select an electrochemical technique.

This command presents an Electrochemical Techniques dialog box:

The following options allow you to select an electrochemical technique:

Technique Selection

Select the electrochemical technique you want to use. This box lists the techniques available in the instrument. Double clicking the technique you want to select is equivalent to selecting the technique and clicking the OK button.

Polarographic Mode

Check this box will enable the polarographic mode. In the polarographic mode, the mercury drop will be allowed to grow and be dislodged for every data point.

Only a few techniques are allowed to have polarographic mode: Sampling Current (Staircase) Polarography (SCP), Differential Pulse Polarography (DPP), Normal Pulse

________________________________________________________________________ Polarography (NPP), Differential Normal Pulse Polarography (DNPP), A.C. Polarography (ACP), and Second Harmonic A.C. Polarography (SHACP).

Once polarographic mode is enabled, stripping mode is disabled. In order to set stripping mode by using the Stripping Mode command in Control Menu, you have to uncheck the polarographic mode.

This command has a toolbar button:

Parameters Command

Use this command to set experimental parameters.

This command presents a Parameter dialog box so you can select the parameters you want to use.

Depending on the technique, the parameters dialog box will be different. The followings are the parameters for different techniques:

Parameters for Cyclic Voltammetry

Parameters for Linear Sweep Voltammetry

Parameters for Sampled Current Voltammetry

Parameters for Tafel Plot

Parameters for Chronoamperometry
