Abstract
The
study and analysis of the materials employed in artistic paintings
provide deeper knowledge about the history of the work of art, including
restoration efforts made in the past, and the development of painting
techniques through the centuries. Gas chromatography coupled to mass
spectrometry is the main analytical technique employed, as it proved to
be the most suitable technique for the analysis of complex mixtures,
thanks to its combination of sensitivity, wide range of applicability
and versatility. Further, μFT-IR technique has also been employed to get
a preliminary screening of the samples taken from paintings. In this
paper, the analytical protocol based on these two techniques has been
applied for analysing natural terpenic resins; its performance has been
tested on microsamples collected from paintings of valuable artistic
interest.
