Abstract
The present invention relates to a method of mass spectrometry, an apparatus adapted to perform the method and a mass spectrometer. More particularly, but not exclusively, the present invention relates to a method of mass spectrometry comprising the step of associating parent and fragmentation ions from a sample by measuring the parent and fragmentation ions from two or more different areas of the sample and identifying changes in the number of parent ions between the areas in the sample, and corresponding changes in the number of fragmentation ions between the two areas.
