calculations.

In the Graph View, zoom in as necessary to view the single
peak.
Position the cursor inside the peak at the horizontal location
where you want to split the peak. (The Split Peak option is not
available if the cursor is an up arrow. Move the cursor until the
peak is not selected.)
Figure 29. Splitting a Peak
Right-click on the graph and select Split Peak on the shortcut
menu. A new Manual Peak is created abutting the original peak.
Exclude one of the peaks from the analysis, following the
procedure "Excluding a Peak" on page
Verify that Show Peak Baselines is selected in the
Properties.
Click and drag the baseline of the remaining peak to include the
area under the excluded peak.
