FTIR-2D mapping for the axial deformation of C=O of enols (β-diketones); (1530–1650 cm−1) of Xanthan gum, for pristine area (i.e. unsoiled and untreated area) (bottom row, a and b), and area cleaned with Xanthan gum (top row, c and d). The corresponding FTIR spectra are shown in the right panel; each spectrum relates to a single pixel (5 × 5 µm2) of the corresponding 2D imaging map. Image © Tate and CSGI
