Score plot and loading plot obtained in the PCA of the ESI-Q-ToF data for the 2006 Winsor&Newton paint models during artificial ageing in wet (W, blue dots) and dry (D, red dots) conditions. The suffix number indicates the number of weeks of artificial ageing before sampling. WN 0 (empty dot) corresponds to the sample collected before starting the artificial ageing.
