Abstract
Parchments from various animal skin sources were analyzed using LIBS to obtain surface distribution and depth profile of elements such as Na, Cl, Cu, Fe, K, Mg, and Mn. Internal distribution of fluorophores in parchment layers was investigated by laser breakdown ablation (LBA) followed by synchronous fluorescence (SF). Inductively coupled plasma-optical emission spectroscopy (ICP-OES) using an Optima 3000V from PerkinElmer, served as reference technique for LIBS measurements. The results show that the identification of animal type is required for the parchment restoration procedure, and the intensity ratio of Mg/Cu allows statistically significant differentiation between animal types from which the parchment is made. Spectral characteristics of the bulk fluorescence are affected by the variation in the animal skin layer's thickness.
