Claim 5:
6. A method for conducting mass analysis in which the equilibration time increases in response to a decrease in ion beam transmission, comprising:
in a first mass analysis cycle,
attenuating an ion beam to a first percentage transmission value and
selecting one or more precursor ions of the attenuated ion beam with a mass filter after a first equilibration time, wherein the first equilibration time is greater than the second equilibration time; and

in a next mass analysis cycle immediately following the first mass analysis cycle,
determining a second percentage transmission value using the first percentage transmission value and at least one other experimental parameter,
determining that the second percentage transmission value is less than the first percentage transmission value,
selecting a second equilibration time that is greater than the first equilibration time,
attenuating the ion beam to the second percentage transmission value, and
selecting one or more precursor ions of the attenuated ion beam after the second equilibration time.
