The analytical methods that are usually applied to determine the compositions of inks from ancient man- uscripts usually focus on inorganic components, as in the case of iron gall ink. In this work, we describe the use of atmospheric pressure/matrix-assisted laser desorption ion- ization – mass spectrometry (AP/MALDI-MS) as a spatial- ly resolved analytical technique for the study of the or- ganic carbonaceous components of inks used in hand- written parts of ancient books for the first time. Large polycyclic aromatic hydrocarbons (L-PAH) were identi- fied in situ in the ink of XVII century handwritten doc- uments. We prove that it is possible to apply MALDI- MS as a suitable microdestructive diagnostic tool for analyzing samples in air at atmospheric pressure, thus simplifying investigations of the organic components of artistic and archaeological ob jects. The interpretation of the experimental MS results was supported by indepen- dent Raman spectroscopic investigations.
