Abstract

In this work, several applications about carbon detection by LIBS for identification and quantification purposes and for assistance during the surface cleaning of materials will be presented. The first set of applications focuses on the qualitative analysis of polymers where the interest was to determine the presence of carbon and other elements for identification of their compounds. In the second case, the carbon lines monitored during laser cleaning process allowed to control the removal of surface contaminants located on specimens covered by dense layers of hydrocarbons coming from oil spill residues. Finally, two examples of quantitative measurements were achieved on coal and fly ashes specimens coming from a coal-fired power station. In this last application, the utilization of an adequate procedure of data processing is crucial since quantification is one of the major difficulties which limit the progress of LIBS technique toward a mature analytical tool..
