This paper contains summary results from work in a number of applications of LIBS. Most application use multivariate/chemometric methods Tree samples are analysed investigating the effect of fire. Soil samples are analysed for carbon content. Cremated remains are analysed for Pb and Cu content, and the titanium content of a prosthetic was also investigated.
