Abstract

We propose a calibration-free algorithm for retrieval of elemental concentrations using laser-induced breakdown spectroscopy. This is a simple and improved version of other ratio-based algorithms as it needs only one trial parameter to estimate all other concentrations. The present algorithm has been used to estimate the composition of a brass sample, and the results agree within 1% with electron probe microanalyzer measurements.
