Abstract: There are provided processes for analysing a plurality of different samples. The processes comprise the steps of: a) applying the samples to a support, to which an analytical component is immobilised; and b) allowing the samples to interact with the analytical component, thus permitting analysis of the samples. The samples are applied in step a) to different areas of the support to produce a spatial arrangement of samples on the support. The spatial arrangement of the samples is maintained in step b), thus permitting the results of the analysis to be matched to individual samples.
