Evaluation of Degradation of Japanese Hanging Scrolls Using Relative Peak Area of Volatile Organic Compounds

Volatile organic compounds (VOCs) generated from naturally aged Japanese hanging scrolls and their model samples were measured using solid-phase microextraction-gas chromatography-mass spectrometry (SPME-GC-MS) to clarify the effect of different painting papers raw materials on degradation state scrolls. VOC-based markers identified applicability was considered for evaluations actual The relative peak areas VOC groups calculated by normalising total area long-chain hydrocarbons. When a paper immersed in CuSO4?5H2O solution, or coated with an alum furfural carboxylic acids increased after accelerated ageing, while these decreased when animal glue applied, indicating that inhibited generation VOCs. containing Cu2+ stacked lining paper, migrated into ageing. Animal retarded this migration paper. For wheat starch paste, furfural, acids, aliphatic aldehydes did not change significantly paste contribute degradation, although applied. These results indicate targeted VOCs are valid
