Claim 10:
11. A mass analysis system comprising:
a mass analyzer operative to:
receive an ion beam;
attenuate the ion beam with a skimmer to a percentage transmission value, wherein the percentage transmission value is a percentage of the ion beam not attenuated; and,
select one or more precursor ions of the attenuated ion beam with a mass filter after an equilibration time selected from at least a first equilibration time and a second equilibration time, wherein the first equilibration time is greater than the second equilibration time;

a detector operative to:
detect the selected one or more precursor ions; and,
provide a mass analysis signal representative of the detected one or more precursor ions in a current mass analysis cycle to computing resources controlling the mass analysis system;

the computing resources operative to:
in a first mass analysis cycle, control the mass analyzer to attenuate the ion beam to a first percentage transmission value and select one or more precursor ions of the attenuated ion beam with a mass filter after the first equilibration time,
in a next mass analysis cycle immediately following the first mass analysis cycle, determine a second percentage transmission value using the first percentage transmission value and at least one other experimental parameter, determine that the second percentage transmission value is greater than the first percentage transmission value, select the second equilibration time, control the mass analyzer to attenuate the ion beam to the second percentage transmission value and select one or more precursor ions of the attenuated ion beam with a mass filter after the second equilibration time.
