XRF is a suitable tool for studies of cultural heritage, since it provides valuable information about the chemical composition of an artefact by means of a non-invasive, multi-elemental and non-destructive in situ analysis. This work presents and discuss the technical examination of the Portrait of a Young Man with a Golden Chain (c. 1635), a wood panel historically attributed to Rembrandt van Rijn and/or atelier, from the São Paulo Museum of Art (MASP) collection. Rembrandt was a Dutch painter, considered one of the greatest visual artists in the history of art. Besides his great success as a historical painter and portraitist, Rembrandt ran large workshops and had a large number of pupils and assistants. In situ PXRF were performed for the elemental characterization of the pigments presents in the painting. The results make possible the characterization of the original materials presents in the painting. Some of the materials identified were Lead White, Chalk, Vermilion, Bone Black, Azurite, Smalt, and earth pigments, such as Red, Yellow and Brown Ochres.

XRF是研究文化遗产的合适工具，因为它通过非侵入性，多元素和非破坏性的原位分析提供了有关人工制品化学成分的宝贵信息。该作品介绍并讨论了《金链青年肖像》（约1635年）的技术检查，这是历史上归因于伦勃朗·范·赖恩和/或工作室的木板，来自圣保罗艺术博物馆（MASP）。 。伦勃朗是荷兰画家，被认为是艺术史上最伟大的视觉艺术家之一。除了作为历史画家和肖像画家获得巨大成功外，伦勃朗还举办大型讲习班，并有大量的学生和助手。原位进行PXRF以对绘画中存在的颜料进行元素表征。结果使得表征绘画中存在的原始材料成为可能。确定的一些材料包括铅白，白垩，朱红色，骨黑，石青，Smalt和泥土颜料，例如红色，黄色和棕色O石。
