“…A great advantage of TOF‐SIMS imaging lies in the possibility to simultaneously detect and localize organic and mineral components in a sample which is usually unique and inestimable. A study has been published in the case of samples coming from African wooden statuettes, where silicon and aluminum as well as characteristic ions from proteins were mapped (Mazel et al, ). The various materials used for painting can also be studied by this imaging method as done on the Issenheim altarpiece, from Matthias Grünewald, a renaissance painter, as well as on Rembrandt paintings (Richardin et al, ; Sanyova et al, ).…”

Recent developments in instrumentation, ion beams or analyzers, for cluster time-of-flight secondary ion mass spectrometry (TOF-SIMS) imaging are described here. The methods which are employed to increase the sensitivity or to perform three-dimensional analyses in the organic materials are also illustrated. This review shows the improvements made for lipid imaging by cluster TOF-SIMS in various types of material and applications, and gives reasons for the expansion of its utilization.

“…recommended dry-polishing the surface of the sample embedded in resin with fine polishing cloths. Other studies describe the use of microtomy [Saito et al 2008] or ultramicrotomy [Mazel et al 2006] to cut the surface. This allows very flat surfaces to be obtained and avoids contact with possible contaminants from polishing cloths.…”

“…Indeed, in a unique analysis, performed in positive and negative ion mode, a great number of different compounds can be detected. This is well illustrated by the study of a sample from the Dogon statuette 73.1964.3.39 from the Musée du Quai Branly (Paris) [Mazel et al 2006]. A multi-method protocol was performed on complex samples of patina from African art.…”

“…ToF–SIMS has previously been shown as a useful technique in the field of art conservation [33–36]. The technique has been proven for its ability to co-localize the various components of paint, as well as show signs of binder and/or pigment degradation [37–39].…”

ToF–SIMS imaging of molecular-level alteration mechanisms in Le Bonheur de vivre by Henri Matisse

et al. 2015

Time-of-flight secondary ion mass spectrometry (ToF–SIMS) has recently been shown to be a valuable tool for cultural heritage studies, especially when used in conjunction with established analytical techniques in the field. The ability of ToF–SIMS to simultaneously image inorganic and organic species within a paint cross section at micrometer-level spatial resolution makes it a uniquely qualified analytical technique to aid in further understanding the processes of pigment and binder alteration, as well as pigment–binder interactions. In this study, ToF–SIMS was used to detect and image both molecular and elemental species related to CdS pigment and binding medium alteration on the painting Le Bonheur de vivre (1905–1906, The Barnes Foundation) by Henri Matisse. Three categories of inorganic and organic components were found throughout Le Bonheur de vivre and co-localized in cross-sectional samples using high spatial resolution ToF–SIMS analysis: (1) species relating to the preparation and photo-induced oxidation of CdS yellow pigments (2) varying amounts of long-chain fatty acids present in both the paint and primary ground layer and (3) specific amino acid fragments, possibly relating to the painting’s complex restoration history. ToF–SIMS’s ability to discern both organic and inorganic species via cross-sectional imaging was used to compare samples collected from Le Bonheur de vivre to artificially aged reference paints in an effort to gather mechanistic information relating to alteration processes that have been previously explored using μXANES, SR-μXRF, SEM–EDX, and SR-FTIR. The relatively high sensitivity offered by ToF–SIMS imaging coupled to the high spatial resolution allowed for the positive identification of degradation products (such as cadmium oxalate) in specific paint regions that have before been unobserved. The imaging of organic materials has provided an insight into the extent of destruction of the original binding medium, as well as identifying unexpected organic materials in specific paint layers.
