This work regards the analysis of a copper-based door (dated 1076 AD) located at the entrance to the sanctuary of Monte Sant’Angelo (Southern Italy) by using a non-destructive technique and in situ chemical analysis. The door does not show serious corrosive phenomena and presents several types of decorative elements such as two inlays (of silver and copper colour) and three engravings (of red, black and green colour). A portable energy dispersive X-ray fluorescence (ED-XRF) spectrometer was used in order to evaluate the chemical composition of the door and of the decorations that adorn the artefact. No sampling or sample preparation was required before the measurements. Preliminary analysis on the materials that make up the door revealed that the panels and the frame of the two sashes are made of the same alloy, while the nails and the handles have a different composition.

蒙特圣安杰洛（意大利南部）中世纪铜基门的ED-XRF分析

这项工作涉及通过使用非破坏性技术和原位化学分析对位于圣安杰洛山（意大利南部）圣所的入口处的铜制门（公元1076年）进行分析。门没有显示出严重的腐蚀现象，并且呈现几种类型的装饰元素，例如两个镶嵌（银色和铜色）和三个雕刻（红色，黑色和绿色）。为了评估门和装饰人造物的装饰品的化学成分，使用了便携式能量色散X射线荧光（ED-XRF）光谱仪。测量之前不需要取样或样品制备。对构成门的材料的初步分析显示，两个窗扇的面板和框架由相同的合金制成，
