Options

General parameters for peak evaluation.

Manual

Manual peak evaluation. The base points for
baseline evaluation must be set manually.

Automatic

Automatic peak evaluation. The base points for
baseline evaluation are evaluated automatically.

Reverse peak

Enable peak evaluation of reverse peaks (peaks
with opposite direction compared to the sweep
direction: negative peaks with anodic sweeps;
positive peaks with cathodic sweeps).

Reverse sweep

Enable peak evaluation of the reverse sweep of
cyclic voltammograms (only available with CV).

Minimum peak width (V.step

)

[ 0 ; 10 ]

Minimum peak width for peak recognition by
number of

Voltage steps

(= number of measure-

ment points).

Minimum peak height (A) [ > 50 pA ; 100 pA ]

Minimum peak height for peak recognition.

Smooth factor [ 1...6 ; 3 ]

Smoothing power for the Savitzky/Golay smooth-
ing of the baseline (

1

= minimum smoothing,

6

=

maximum smoothing).

Baseline

Parameters for baseline evaluation.

Begin (V) [ Start potential...End potential ; - ]

Manual setting of the start base point for baseline
evaluation. The values can be increased or de-
creased by clicking the buttons of the field
