Delta Ep

The Delta Ep command is used to determine the potential difference between two peaks. In order to use this command, first you must find two or more peaks with the Peak Find command.

Method

1. Use the Peak Find command to locate two or more peaks. Notice that there is a subscript number, which tells the number of the peak (in this case, a 1 and a 2). These numbers allow you to know which peak is which in the Delta Ep window.
2. Select the Delta Ep command from the document menu. The Delta Ep window opens.
3. Click on a peak in the First Peak list, and a different peak in the Second Peak list. The potential difference between the two peaks is displayed in the Result area.
4. The Update Peak Lists button lets you refresh the peaks in the lists, if you decide to leave this dialog box open while you perform another Peak Find.
