Abstract
A method of operating a multipole device comprises sorting a list of mass-to-charge ratios that are assigned to one of first and second polarity configurations to be applied between first and second pairs of opposing electrodes, the first polarity configuration being a first polarity DC offset and the second polarity configuration being a second, opposite polarity DC offset; and based on the sorting, operating the multipole device for a first time duration according to the first polarity configuration to select ions having mass-to-charge ratios from the list that are assigned to the first polarity configuration and operating the multipole device for a second, distinct time duration according to the second polarity configuration to select ions having mass-to-charge ratios from the list that are assigned to the second polarity configuration.
