在这项工作中，我们已经建立了一个便携式X射线荧光（XRF）光谱仪在一个平面配置耦合到一个拉曼头和一个数字光学显微镜，在原位分析。XRF设备和数字显微镜的几种几何形状是可能的，以便克服空间限制并提供更好的测量条件。有了这款组合光谱仪，我们现在能够在同一点进行XRF和拉曼测量，而无需进行样品采集，这在处理文化遗产物品以及法医分析时至关重要。我们通过测量几种标准参考物质以及文化遗产、地质和生物医学研究中通常遇到的其他样品来展示光谱仪的功能。
In this work, we have built a portable X-ray fluorescence (XRF) spectrometer in a planar configuration coupled to a Raman head and a digital optical microscope, for in situ analysis. Several geometries for the XRF apparatus and digital microscope are possible in order to overcome spatial constraints and provide better measurement conditions. With this combined spectrometer, we are now able to perform XRF and Raman measurements in the same point without the need for sample collection, which can be crucial when dealing with cultural heritage objects, as well as forensic analysis. We show the capabilities of the spectrometer by measuring several standard reference materials, as well as other samples usually encountered in cultural heritage, geological, as well as biomedical studies.
