3. In the Mass Tolerance field, type the value to dictate the mass range used to find a
peak. The software finds the peak using a value twice the typed range (± the mass
value).
4. In the Minimum Intensity field, type the intensity below which peaks are ignored by
the algorithm.
5. In the Minimum Mass field, type the mass that determines the beginning of the scan
range.
6. In the Maximum Mass field, type the mass that determines the end of the scan
range.
7. To set the start and end times, select the Use Limited Range check box and do the
following:
• In the Start Time field, type the time that determines the start of the
experiment.
• In the End Time field, type the time that determines the end of the experiment.
