Cyclic voltammetry waveforms are defined manually on the Chromeleon 6.8
electrochemical detector Control panel. Click the
CV Mode button to display
the following window.
Integrated Amperometry Waveforms
Integrated amperometry waveforms are included in an instrument method in
Chromeleon 7 or a program in Chromeleon 6.8. 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.
•
The maximum waveform period is 2.0 s. However, for 2D data, because
only one data point is generated per waveform period, the effective
maximum length of a waveform period depends on the
data collection
rate (the rate at which Chromeleon collects digital data points from the
detector). The relationship is as follows:
•
Multiple waveforms can be defined for a single run, provided they all
have the same cycle duration. Up to 15 waveform changes per run are
allowed.
•
Each waveform can have only one integration interval. However, 3D
amperometric data can be reprocessed after the run with integration
intervals at multiple points in the waveform (see
Section 2.19.5 ).
•
The integration interval generates one integrated data point per waveform.
