“…Several analytical techniques have been used for this purpose, for example gas chromatography/mass spectrometry, UV-visible spectrophotometry, thin-layer chromatography, high-performance liquid chromatography, reversed phase liquid chromatography and capillary electrophoresis with electrospray mass spectrometric detection, FT-IR spectroscopy and Raman spectroscopy (6). Differences between IR and Raman spectroskopy are listed in Table 1.…”

“…In order to obtain information on the distribution of both organic and inorganic materials, layers were selectively sampled (when possible) using tungsten needles [21] under the stereomicroscope. The identification of the different materials in the sample spectra was made by comparison with reference data [19,22-30]. …”

BackgroundEstablishing the distribution of materials in paintings and that of their degradation products by imaging techniques is fundamental to understand the painting technique and can improve our knowledge on the conservation status of the painting. The combined use of chromatographic-mass spectrometric techniques, such as GC/MS or Py/GC/MS, and the chemical mapping of functional groups by imaging SR FTIR in transmission mode on thin sections and SR XRD line scans will be presented as a suitable approach to have a detailed characterisation of the materials in a paint sample, assuring their localisation in the sample build-up. This analytical approach has been used to study samples from Catalan paintings by Josep Maria Sert y Badía (20th century), a muralist achieving international recognition whose canvases adorned international buildings.ResultsThe pigments used by the painter as well as the organic materials used as binders and varnishes could be identified by means of conventional techniques. The distribution of these materials by means of Synchrotron Radiation based techniques allowed to establish the mixtures used by the painter depending on the purpose.ConclusionsResults show the suitability of the combined use of SR μFTIR and SR μXRD mapping and conventional techniques to unequivocally identify all the materials present in the sample and their localization in the sample build-up. This kind of approach becomes indispensable to solve the challenge of micro heterogeneous samples. The complementary interpretation of the data obtained with all the different techniques allowed the characterization of both organic and inorganic materials in the samples layer by layer as well as to establish the painting techniques used by Sert in the works-of-art under study.

“…12, in comparison with its second derivative profile. The calcite (712 cm À1 ) ultramarine blue (694 cm À1 ) [25] and gypsum (669 and 602 cm À1 ) [11] bands are clearly observed. The other characteristic bands of ultramarine blue at 666 and 584 were inferred from the second derivative profile [25][26][27].…”
