Laser Induced Breakdown Spectroscopy (LIBS) can be successfully used for cultural heritage applications, such as pigment and stone identification or archaeological metal characterisation. In this work we focus on the study of wall painting pigments. Two methods of signal analysis are tested. The first one is based on spectral lines identification in order to detect characteristic chemical elements. In the second one, we apply chemometrics models (SIMCA and PLS-DA) to a pigment reference database. Results show the improvement of pigments identification obtained with the multivariate analyses approach. This work includes laboratory study and on site validation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
