文化遗产材料分析中的取样限制大大缩小了适当分析方法的选择范围。在这项工作中，近和中FT-IR反射率数据与使用偏最小二乘法的经典分析方法确定的纸张性能。非破坏性测定性能，这对于评估历史纸的长期稳定性非常重要，即，灰分含量、木质素含量、纤维素聚合度、pH和铝含量是可能的。随着大量样品的使用，除了铝含量外，所有性能都达到了令人满意的可靠性。考虑到随着时间的推移，纸张的化学性质发生了变化，首次尝试对历史文献进行断代，也取得了成功。
Sampling restrictions in analysis of cultural heritage materials narrow the choice of appropriate analytical methods considerably. In this work, near- and mid-FT-IR reflectance data were related to paper properties determined with classical analytical methods using partial least-squares. Nondestructive determination of properties, which are of importance for evaluation of the long-term stability of historical paper, i.e., ash content, lignin content, degree of polymerization of cellulose, pH, and aluminum content, is possible. With the use of a considerable sample set, satisfactory reliability was achieved for all properties but aluminum content. Considering that with age, chemical properties of paper change, dating of historical documents was attempted for the first time, also with success.
