792 BASIC IC / Process / Peak editor
The peak editor mode is used for subsequent manual correction of the
automatic integration for chromatogram peaks (see section 4.4.4). It
can be used to select the most important points for the peak evaluation
(start, end and top of peak, valley between peaks) and move them to
the required position.
If the peak editor mode is enabled, the vertical bar cursor appears in
the chromatogram window. At the same time, the Peak menu appears in
the menu bar and the peak editor icons appear in the icon bar of the
main window.
The peak editor mode is switched on or off by clicking on or by
pressing [ Alt ] + [ C ]. It is also possible to click the right mouse button
somewhere in the chromatogram window and to select the Peak editor
item.
You cannot edit the peak pattern while the component table is active
and vice versa, when the peak editor mode is switched on the compo-
nent table option is disabled.
