Clarity Chromatogram

5.4.2 Peak Modifications

The Peak submenu and the corresponding toolbar contain peaks

operations with.

Fig. 20. The Peaks Toolbar

The positions of peak beginnings and ends as well as of valleys or

separating vertical lines can be changed. Invoke the command, move

the cursor to the required location and click to confirm. Abandon the

command may be at anytime by right clicking the mouse button or

hitting the

Esc key. Since only a single peak beginning or end can be

shifted to any place selected on the chromatogram without shifting the

apex, it is unnecessary to specify the peak to which the operation refers.

Note: The preceding sentence does not apply to tangential separations

where, if the required location lies inside the main peak, modification

of the tangentially separated peaks is given preference.

Shifting the peak beginning

The Start command or

icon defines a new position of the peak

beginning. In the event the peak beginning is shifted before the end of

the preceding peak, a vertical line will separate those peaks and its

position will coincide with the new peak beginning. If the peaks are

separated by a vertical line or connected at the valley and the peak

beginning is shifted closer to the apex, the peaks will be separated.
