- Abstract:
- In this study, double-pulse micro-laser induced breakdown spectroscopy (DP-µLIBS) associated to optical microscopy was applied to obtain a microscale three dimensional compositional mapping of a limestone monument encrusted quoin before and after its laser cleaning treatment. Mapping was carried out microdestructively by scanning the laser beam across the stone sample rough surface without further preparation. The compositional maps of the elements were obtained from the intensity of their DP-µLIBS emission lines.DP-µLIBSmapping analysis of the limestonewas able to discriminate effectively between elements originating from alteration mineralogy and elements of the matrix.
