A methodology for capillary electrophoresis/electrospray ionisation mass spectrometry (CE/ESI-MS) was developed for the simultaneous analysis of degradation products from paper among two families of compounds: low molar mass aliphatic organic acids, and aromatic (phenolic and furanic) compounds. The work comprises the optimisation of the CE separation and the ESI-MS parameters for improved sensitivity with model compounds using two successive designs of experiments. The method was applied to the analysis of lignocellulosic paper at different stages of accelerated hygrothermal ageing. The compounds of interest were identified. Most of them could be quantified and several additional analytes were separated.
建立了毛细管电泳/电喷雾电离质谱（CE/ESI-MS）方法，用于同时分析两种化合物家族——低相对分子质量脂肪族有机酸和芳香族（酚类和呋喃类）化合物——的纸降解产物。通过两次实验设计优化 CE 分离和 ESI-MS 参数，以提高模型化合物的灵敏度。该方法应用于加速湿热老化不同阶段的木质纤维素纸分析。鉴定出了感兴趣的化合物。其中大部分可以定量，并且分离出了几个其他的分析物。
