Knowledge about the carbohydrate composition of pulp and paper samples is essential for their characterization, further processing, and understanding the properties. In this study, we compare sulfuric acid hydrolysis and acidic methanolysis, followed by GC–MS analysis of the corresponding products, by means of 42 cellulose and polysaccharide samples. Results are discussed and compared to solid-state NMR (crystallinity) and gel permeation chromatography (weight-averaged molecular mass) data. The use of the hydrolysis methods in the context of cellulose conservation science is evaluated, using e-beam treated and artificially aged cellulose samples.

纤维素样品的比较水解分析及其在保护科学中的应用

关于纸浆和纸张样品的碳水化合物组成的知识对于它们的表征、进一步加工和了解特性至关重要。在这项研究中，我们通过 42 个纤维素和多糖样品比较了硫酸水解和酸性甲醇分解，然后对相应产物进行了 GC-MS 分析。讨论结果并与固态 NMR（结晶度）和凝胶渗透色谱（重均分子量）数据进行比较。使用电子束处理和人工老化的纤维素样品评估了水解方法在纤维素保护科学背景下的使用。
