Portable energy-dispersive X-ray fluorescence spectroscopy (pXRF) was employed in the characterization of the pigments present in the painting "Still Life with Vase, Plate and Flowers", of unknown authorship, but previously attributed to Vincent van Gogh, belonging to the collection of the São Paulo Museum of Art (MASP). In situ pXRF measurements were carried out by means of a portable system in order to provide the museum with a scientific documentation about the materials in the painting. Spectra were taken at different color regions and different hues in the pictorial layer. Some of the materials identified in the painting were chalk and/or gypsum, lithopone, lead white, zinc white, bone black, barium yellow, chrome yellow, yellow ochre, chrome green, Prussian blue, cobalt blue, vermilion and red earth. Besides that, it was possible to suggest the use of a lake pigment. The pigments whose use is suggested by this work are in total agreement with those available to European artists in the end of the 19th century.
便携式能量色散X射线荧光光谱法（pXRF）被用于对一幅名为《花瓶、盘子和花朵的静物》的画作中的颜料进行表征。这幅画作者不详，但此前被认为是文森特·梵高的作品，属于圣保罗艺术博物馆（MASP）的藏品。通过便携式系统进行了原位pXRF测量，以便为博物馆提供有关这幅画中材料的科学记录。在画面层的不同颜色区域和不同色调处采集了光谱。在这幅画中鉴定出的一些材料有白垩和/或石膏、立德粉、铅白、锌白、骨黑、钡黄、铬黄、赭黄、铬绿、普鲁士蓝、钴蓝、朱砂和红土。除此之外，还可能暗示使用了色淀颜料。这项工作所表明使用的颜料与19世纪末欧洲艺术家可获得的颜料完全一致。
