Automatic Peak Integration Settings
In the Peak Integration pane, the Auto Integration tab displays settings that affect
baseline calculation and peak detection. Changing these settings enables you to
optimize the way peaks are detected and recognized, specific to your data.
Note: By default most tab sections are collapsed. Expanding the sections
displays the options shown in the following illustration.
Traces
A list of shown UV traces grouped by run. By default all
shown UV traces are selected for peak integration.
You can exclude traces from integration by clearing their
checkboxes.
Baseline Parameters
You can select from two baseline calculation methods.
By Best Fit — the baseline is calculated from the data.
The baseline curve connects the low points of the data.
This setting describes the radius of a disk rolling along
the curve from underneath.
By default, the best fit radius parameter is set to 8. This
value can to be set from 1 to 10. The smaller the radius,
the more low points on the curve it touches.
By Offset — the baseline is a straight horizontal line
that has a constant offset (y) value. The default value is
zero, but you can specify a different offset value.
