Setting up a Fraction Collector Method

Fraction Trigger Mode
Use Timetable: Enables the Timetable, but requires a timetable event.
Peak-based: If Peak-based is selected, the collection of a fraction is triggered by
the signal of the detector. The detailed trigger conditions are specified in the Peak
Detectors table. In the peak-based trigger mode all entries in the timetable are
ignored.
Max. Peak Duration: Defines a maximum collection time in case that the signal
does not reach the condition to cut the fraction as exhibited in
page 56. This could be caused by tailing peaks or if the baseline is drifting during
gradient runs. The default value is set to 0.5 minutes. If broad peaks are
expected, this value should be increased without exceeding the run time.
