1. A method of analysis of data produced from the imaging of a substrate comprising the steps of:

  • ionizing a sample of interest at multiple predetermined positions upon the sample,producing a mass spectrum of the ionized sample at each of said multiple predetermined positions using a Mass Analyser,creating an overall spectrum for the whole sample,selecting a number of peaks within the overall spectrum,creating a scan distribution for at least some of said selected peaks, andcomparing the scan distributions to identify correlations between different analytes within the sample.
