Use Peak Trigger
Set Peak Trigger in Time-Based Mode
If the
Use
check box is selected, the peak detection settings are used for finding
and marking
1
D peaks within the reference chromatogram in the preview UI. This
means that first a known
1
D reference chromatogram of the instrument must be
loaded and then can be used to detect the correct position of sample peaks for a
complete 2D-LC measurement.
1
The found cuts are displayed in grey triangles in the preview of the reference
chromatogram, see reference chromatogram.
Set Peak Trigger in Peak-Based Mode
If the
Use
check box is selected, the peak trigger settings are used to trigger the
sampling and parking of cuts from the first dimension. This means that the areas
of interest must be predefined by the method (See sampling table). If a peak
appears in the
1
D detector and the threshold (or slope) is reached, the 2D-LC
modulator starts sampling then the found peaks are parked and analyzed in the
second dimension.
1
To enable/disable the peak trigger of the
1
D detector, mark the
Use
check box.
In time-based mode, depending on the peak trigger settings, peaks can be
marked in the preview of the loaded reference chromatogram.
In peak-based mode, the peak trigger settings can be used for online
peak-triggered 2D-LC operation.
2
Select the peak trigger
Detector
from the drop-down list.
3
Select the signal for the peak-based mode from the
Peak detection mode
drop-down list.
