Define Peak Detector Parameter

This section allows parameterizing the peak detector to be used for
peak-triggered 2D-LC operation (comprehensive or heart cutting).

The stop time for a 2D-LC measurement must be set for the 2D pump, which can
be accessed through the advanced settings. It must be at least the 1D run time
and applies to the entire measurement, not to partial 2D-only runs/gradients for
parked peaks.
Multiple Heart-Cutting automatically extends this run time, if required, as
analyzing parked peaks takes usually longer than the 1
If you define a 1D stop time, it will be applied unchanged, for example the
analysis will stop after that time without processing any parked peaks. This is not
recommended and will lead to a warning in the gradient preview.
