摘要
文化遗产的气味不仅反映了文物的历史信息,还对文化遗产自身产生持续性的影响,因此了解文化遗产的气味对其价值研究和当代保护都具有重要意义。本工作采用固相微萃取-气相色谱-质谱技术对中国国家博物馆藏《江友渚等七挖书画轴》天头用纸散发的气体进行了采集、分离和分析。结果表明:与纸张降解相关的标志物(如脂肪酸、醛、酮等)得到有效采集;而其他生物标记物(如沉香螺醇)的检出也反映了该书画轴的历史保存环境信息。此方法对该件书画轴的历史价值认知和科学保护具有重要作用。
The odors of cultural heritage objects not only reflect their historical information,but also have lasting impacts on the objects themselves.Therefore,understanding the odors of cultural heritage objects is of great significance for research and contemporary conservation.In this work,solid phase microextraction(SPME)and gas chromatography-mass spectrometry(GC-MS)were used to collect,separate and analyze the odors emitted from the head margin paper of a scroll painting collected in the National Museum of China.The results show that the method could effectively collect markers related to paper degradation(such as fatty acids,aldehydes and ketones).In addition,the detection of other biomarkers(such as agarospirol)also reflects information about the historical preservation environments of the scroll.This method plays an important role in understanding the historical value and scientific conservation of the painting.
