Investigating Brazilian Paintings from the 19th Century by MA-XRF

Quantum Beam Science, 2023
In this work, four artworks dating from the 19th century by Brazilian painters Firmino Monteiro, Henrique Bernardelli, and Eliseu Visconti were analyzed by MA-XRF. Pb-L, Fe-K, and Hg-L were the main elemental maps obtained in all paintings.

Characterisation of corrosion products on copper-based artefacts: potential of MA-XRF measurement [PDF]

ACTA IMEKO, 2021
The use of macro-X-ray fluorescence (MA-XRF) scanners is now widespread in cultural heritage applications. However, its use for the characterisation of metallic works of art is still limited. In this study, a novel portable MA-XRF scanner prototype was tested on artificially corroded copper samples to assess its analytical capabilities on corroded ...
