A method is disclosed comprising applying a reversal agent, such as urea, to a formalin fixed tissue sample in order to reverse the effects of the fixation process. An ambient ionisation ion source such as a desorption electrospray ionisation ("DESI") ion source is used to generate analyte or analyte ions from multiple regions of the modified target so that an ion image of the modified target may be generated.
