Calibration-free laser-induced breakdown spectroscopy
Résumé
The purpose of this chapter is to give an introductive overview on the so-called calibration-free laser-induced breakdown spectroscopy that enables straightforward compositional analysis of materials via modeling of the plasma emission spectrum, without any need of measurement calibration with standard samples. The proposed physical models, their validity conditions, and the experimental requirements are discussed. Based on results reported in literature, a critical review of the analytical performance is given. Finally, the remaining challenges are outlined, and a tentative picture of the perspectives in terms of further improvements and potential applications is drawn.
