Method of mass analyzing a sample over a wide mass range by use of a quadrupole ion trap

The method of operating a quadrupole ion trap in which the mass range of interest is analyzed in segments by trapping ions of successive mass ranges within the segments whereby the operating parameters for each segment may be selected to improve sensitivity and resolution.
