The analysis of archeological artifacts, due to the high value of antique objects, is preferably performed by nondestructive, noninvasive, and in situ techniques. At present, the most common in situ protocols used for the analysis of organic materials are spectroscopic approaches. In this work, we tested selected-ion flow tube-mass spectrometry (SIFT-MS), a transportable mass spectrometry system for the characterization and discrimination of natural resins by the analysis of their volatile organic compounds profiles. We chose diterpenoid, triterpenoid, and aromatic resins as reference materials, focusing on the most identified in archeological artifacts. This work aims to create a SIFT-MS database of mass spectra suitable for characterizing archeological samples. The spectral data obtained by SIFT-MS were interpreted with the aid of chromatograms and mass spectra obtained by head space-gas chromatography/mass spectrometry (HS-GC/MS). Finally, principal components analysis (PCA) was used to further underline the differences among the different materials and to investigate the possibility of discriminating different classes of resins based on their SIFT spectra.

选择离子流管质谱法研究天然树脂的挥发性有机化合物

由于古董物品的高价值，考古文物的分析最好通过非破坏性、非侵入性和原位技术进行。目前最常见的原位用于分析有机材料的协议是光谱方法。在这项工作中，我们测试了选择离子流管质谱 (SIFT-MS)，这是一种便携式质谱系统，用于通过分析其挥发性有机化合物分布来表征和区分天然树脂。我们选择了二萜类、三萜类和芳香族树脂作为参考材料，重点关注考古文物中鉴定最多的物质。这项工作旨在创建一个适合表征考古样品的 SIFT-MS 质谱数据库。通过 SIFT-MS 获得的光谱数据借助通过顶空-气相色谱/质谱 (HS-GC/MS) 获得的色谱图和质谱进行解释。最后，
