Laser Induced Breakdown Spectroscopy (LIBS) is a material analysis technique exploiting the composition determination of the plasma induced during the laser ablation process. Due to the versatility of the ablation process, which allows the “vaporization” in the form of plasma (plasma plume) of any solid material, no preparation of the sample under analysis is required. Thanks to the size of the spot of the incident laser (10s-100s m) it is possible to perform compositional analyses having good spatial resolution both lateral (x, y) and vertical (z: stratigraphic analysis).
