Characterisation of molecular markers of paper degradation using CE/PDA and CE/MS
Studying the products formed during the degradation of cellulose, holocelluloses and lignocelluloses in conditions of natural and artificial ageing allows a better understanding of the phenomena involved in the deterioration of paper objects of cultural heritage. Moreover, the identification and quantitation of selected molecules allows targeting possible degradation markers. Molecular indicators can help establish a diagnostic of the chemical and physical changes occurring in paper with time. These molecules belong to the group of carbohydrates (monomers and oligomers), low molar mass organic acids and aromatic compounds (phenolic and furanic). Our group has developed CE/PDA and CE/ESI-MS to identify and quantify these compounds.
