This work addresses the evaluation of an innovative mutianalytical method to assess the conservation state of a fifteenth century palace house. With the goal of reducing the handicaps of field analysis, the in situ spectroscopic assessment, often based on the use of X-ray fluorescence and Raman spectrometers, was complemented by the use of diffuse reflectance infrared Fourier transform spectroscopy. In this manner, its usefulness as a diagnostic tool to discover the origin and mechanisms of the damage caused by atmospheric and infiltration water attacks were thoroughly examined. Moreover, the study was extended in the laboratory to increase the information obtained by nondestructive techniques. The results revealed a severe material loss caused by soluble salts. Thus, a noninvasive sampling method using cellulose patches was tested to study the amount and mobility of salts by means of ion chromatography. Finally, to establish the chemical degradation processes that are occurring in the palace, a chemometric analysis of the quantitative data as well as the construction of thermodynamic models was done to advise on the required restorative actions.

这项工作涉及对一种创新的多分析方法的评估，以评估一座15世纪宫殿式房屋的保存状况。为了减少现场分析的障碍，通常基于使用X射线荧光光谱仪和拉曼光谱仪的现场光谱评估，通过使用漫反射红外傅里叶变换光谱进行了补充。通过这种方式，对其作为一种诊断工具来发现大气和渗透水侵蚀造成的损坏的起源和机制的有用性进行了全面研究。此外，该研究在实验室中进行了扩展，以增加通过无损技术获得的信息。结果表明，可溶性盐导致了严重的材料损失。因此，测试了一种使用纤维素贴片的非侵入性采样方法，以通过离子色谱法研究盐的含量和迁移率。最后，为了确定宫殿中正在发生的化学降解过程，对定量数据进行了化学计量分析，并构建了热力学模型，为所需的修复行动提供建议。图形摘要评估建筑遗产保存状况的多分析方法的不同阶段。
