Volatile organic compounds emitted from historical books made from cotton/linen rag and wood pulp paper have been studied. Different profiles were obtained using different solid-phase microextraction (SPME) fibres to access the compounds involved in the decomposition reactions occurring in cotton/linen rag and wood pulp paper upon natural ageing and precocious/accelerated degradation. Contact headspace solid-phase extraction coupled with gas chromatography/time-of-flight mass spectrometry (GC-TOF-MS) was improved as a non-destructive methodology for the analysis of historical books. Potential markers of cellulose degradation-linear hydrocarbons, linear aldehydes, and 2-furfural-together with potential markers of cotton/linen rag paper (isopropylic esters) were identified. Chiral analysis (SPME-c-GC-TOF-MS) showed that only the enantiomer (S)-2-ethyl-1-hexanol is present as an emanation compound in both types of paper. Validation studies for a larger number of books are being done.
从棉/亚麻碎布和木浆纸制成的历史书籍中释放出的挥发性有机化合物已经过研究。使用不同的固相微萃取（SPME）纤维获得不同的图谱，以接触顶空固相萃取结合气相色谱/飞行时间质谱（GC-TOF-MS）作为一种非破坏性方法来分析棉/亚麻碎布和木浆纸在自然老化和早熟/加速降解过程中发生的分解反应所涉及的化合物。鉴定出纤维素降解的潜在标志物-线性烃类、线性醛类和糠醛-以及棉/亚麻碎布纸的潜在标志物（异丙基酯）。手性分析（SPME-c-GC-TOF-MS）表明，只有对映体（S）-2-乙基-1-己醇作为一种散发化合物存在于两种类型的纸张中。正在对更多的书籍进行验证研究。
