Swords are made from different materials in different eras in different countries. From an archaeological point of view, elemental analysis provides hints of the origin and the production date of a sword. It also provides hints to identify whether it’s imitation or real.

Identification of pigments is important in the archaeological and art research fields. Some pigments were used during specific times and then were no longer used in later times. Therefore, we can estimate the period when artwork was created through identification of the pigments. Micro-XRF is an effective pre-screening analytical technique to narrow down the candidates of multiple pigments used on a painting, thanks to its non-destructive approach and imaging capability.

在这项研究中，我们表征了黄铁矿及其周围的矿物，以确定不同的矿物相态，并从微米到纳米尺度表征了样品空间上的化学变化。使用不同的显微镜仪器进行共定位，实现对样品特征的全面分析，并对所有的图像进行精确的叠加。

青金石是一种深蓝色变质岩，用作半宝石，其中包含会影响其价值的内含物，使用 HORIBA 的新型微区X 射线荧光光谱XGT-9000 研究黄铁矿杂质和主要元素分布。
