TL;DR: In this paper, a new procedure based on the laser-induced plasma spectroscopy (LIPS) technique was proposed for calibration-free quantitative elemental analysis of materials, which allows the matrix effects to be overcome, yielding precise and accurate quantitative results on elemental composition of materials without use of calibration curves.

TL;DR: In this article, a model of self-absorption effect in laser-induced plasma has been developed, with the aim of providing a tool for its automatic correction in the Calibration-Free algorithm recently developed for standardless analysis of materials by LIBS (Laser Induced Breakdown Spectroscopy).

TL;DR: In this paper, the authors proposed a simple method for evaluating the ratio between the actual measured line intensity and the intensity expected in absence of self-absorption and, if necessary, correcting the effect of selfabsorption on line intensity.

TL;DR: In this article, the effects of experimental aberrations and accuracy of spectral data were investigated, under the assumption that the analytical plasma is ideal, and two kinds of metallic alloys, iron-based and aluminum-based, were studied.

TL;DR: In this article, the morphology of plasmas induced by single and double laser pulses was studied, with the purpose to improve the understanding of the formation and evolution of the plume in the two cases and the reasons of the increase of sensitivity and detection limits in the double pulse configuration.
