摘要： A method of operating an instrument which comprises a first and second ion stores, comprising determining whether a target accumulation time for the second ion store is greater than a threshold accumulation time. When the target accumulation time is less than the threshold accumulation time, ions are accumulated within the second ion store using an accumulation time that is based on the target accumulation time. When the target accumulation time is greater than the threshold accumulation time, ions are accumulated within the first ion store using a first accumulation time that is based on a difference between the target accumulation time and the threshold accumulation time, the ions accumulated in the first ion store are passed to the second ion store, and further ions are accumulated within the second ion store using a second accumulation time that is based on the threshold accumulation time.
