dc.description.abstract | A correct determination of the mineral and chemical composition of specimens is of
the utmost importance to answer questions regarding the Cultural Heritage field. Because of
the preciousness and often very low quantity of sample available, with textures and sizes in the
nano-to-micrometric range, scanning electron microscopy (SEM) combined with energy-dispersive
X-ray spectroscopy (EDS) is one of the most suited and exploited nano-microanalytical techniques.
In these cases, to avoid severe mistakes and quantification errors in SEM-EDS, it is mandatory to
consider several effects related to the transport of electrons and X-rays in the material, which in turn are
dependent on the SEM-EDS setup. In the present work, a Monte Carlo SEM-EDS nano-microanalytical
simulation strategy is proposed and applied to a practical selected case. The Egyptian blue mineral
pigment, which is found in Pompeian murals, is used here as an example and model system to show
the effects of real size variations (0.1–10 µm), basic geometrical shapes of the pigment (prismatic
and spherical) and typical SEM setups, sample holders and substrates. The simulations showed a
great—sometimes not intuitive—dependence of the X-ray intensity on the thickness and shape of the
samples and SEM-EDS parameters, thereby influencing the analysis and quantification. The critical
overview of the results allowed the determination of the correct procedure and technical SEM-EDS
parameters and indicated how to apply the Monte Carlo simulation strategy to other Cultural
Heritage cases. | es |
