ABSTRACT:
Method and apparatus of controlling an ion population to be analyzed in a mass analyzer. Ions are accumulated for an injection time interval determined as a function of an ion accumulation rate and a predetermined desired population of ions. The accumulation rate represents a flow rate of ions from a source of ions into an ion accumulator. Ions derived from the accumulated ions are introduced into the mass analyzer for analysis.
