In this example, the potential is scanned from -0.80 to +0.60 V and then
from +0.60 to -0.80 V. The total time for one waveform period is 28 s.
This provides a sweep rate of 0.1 V/s as shown in the equation below.
Cyclic voltammetry waveforms are defined manually on the Chromeleon
or Chromeleon Xpress electrochemical detector Control panel. Click the
CV Mode button to display the following window.
Integrated Amperometry Waveforms
Integrated amperometry waveforms are included in a Program file in
Chromeleon or Chromeleon Xpress. Integrated amperometry waveforms
have the following characteristics:
• The duration of one waveform period can be between 0.05 and 2.0 s,
with a step resolution of 10 ms. A waveform can have no more than
100 steps.
