X-ray fluorescence (XRF) analysis is a powerful approach to discriminate iron-gall inks from different inscriptions. The representativeness of spot measurements is though often impaired by the material history and conservation state of historical artefacts bearing such inscriptions. The method proposed here, using a XRF scanner, not only improved the readability of inscriptions, thanks to the enhanced contrast offered by chemical maps, but also allowed the evaluation of iron, copper and zinc contents of the inks, by the optimised selection in MA-XRF maps of more than 1,000 spectra from each inked area, representing an equivalent analytical surface of several square-millimetres. In addition, the quantitative calibration of the system based on the thin target approximation allowed calculating these elements concentration. This method, applied to a series of ink inscriptions on a set of artefacts from Stradivari's workshop (active from 1666 to 1743) now in the collection of the Musée de la musique (Paris, France), offers a complementary route to the more conventional palaeography- and graphology-based approaches for the potential identification of the authors of the inscriptions.

使用 XRF 成像对铁胆墨水铭文进行化学鉴别：以 Stradivari 工作室为例

X 射线荧光 (XRF) 分析是区分不同铭文中的铁胆油墨的有效方法。现场测量的代表性虽然经常受到带有此类铭文的历史文物的物质历史和保护状态的影响。这里提出的方法，使用 XRF 扫描仪，不仅提高了铭文的可读性，这要归功于化学地图提供的增强对比度，而且还允许通过 MA 中的优化选择来评估油墨的铁、铜和锌含量- 来自每个着墨区域的 1,000 多个光谱的 XRF 图，代表几平方毫米的等效分析表面。此外，基于薄目标近似值的系统定量校准允许计算这些元素的浓度。这种方法，
