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.
