Merge 2D peaks in different cuts

Preparations

• The peaks that you want to merge do not have a nested baseline. You cannot merge nested peaks in different cuts. The identification of 2D compounds using the peak match option Closest Nested is restricted to 2D compound on one single ²D chromatogram.

1. Click the first ²D or 2D peak. Then keep the Ctrl key pressed while clicking the other peaks that you want to merge to one 2D peak.

   NOTE

   All selected peaks must belong to different, adjacent cuts of the same cut series. Merging peaks is only supported with comprehensive 2D-LC data or high-resolution data.

   The clicked peaks, except the last one, are shown with a dashed outline.

   

2. Right-click the Contour Plot 2D, and select Merge selected 2D peaks from the context menu.

   The merged peak is shown with an asterisk at its top right corner.

3. To undo the merging, right-click a peak in the Contour Plot 2D, and select Undo merge/split of 2D peaks from the context menu.
