A novel plug-and-play setup based on polycapillary X-ray optics enables three-dimensional (3D) confocal X-ray fluorescence (XRF) and X-ray absorption spectroscopy down to 8 × 8 × 11 μm (17 keV) at the European Synchrotron Radiation Facility Collaborative Research Group Dutch-Belgian Beamline, BM26A. A complete description and analytical characterization is presented, together with two recently performed experimental cases. In Deep Earth diamond São Luiz-Frankfurt am Main 16, an olivine-rich inclusion was mapped with full 3D XRF elemental imaging. The preliminary tests on Iron Gall ink contained in an historical document, a letter from the court of King Philip II of Spain, reveal both the delicate nature of Iron Gall ink and the lack of Fe-Ni chemical bonding.
一种基于多毛细管 X 射线光学的新型即插即用设置，使欧洲同步辐射设施合作研究组荷兰-比利时光束线 BM26A 能够在 8×8×11μm（17keV）下进行三维（3D）共聚焦 X 射线荧光（XRF）和 X 射线吸收光谱。本文对其进行了完整的描述和分析，同时介绍了最近进行的两个实验案例。在深地钻石 São Luiz-Frankfurt am Main 16 中，富含橄榄石的包裹体进行了全 3D XRF 元素成像。对保存在历史文献（西班牙国王菲利普二世的法庭信件）中的铁胆墨水进行的初步测试，揭示了铁胆墨水的脆弱本质以及缺乏 Fe-Ni 化学键。
