Abstract

A data acquisition approach followed by a suitable data analysis for laser-induced breakdown spectroscopy (LIBS) is developed. It provides absolute concentrations of elements in particulate materials. The proposed compensation for pulse variations is based on the assumption that they can be described as a multiplicative effect for both the spectral peaks and a component of the baseline. It is assumed that the same fluctuation pattern observed in the spectral peaks is present in the baseline as well. The assumption is shown to hold and is utilized in the proposed method. A proper data-filtering process, which eliminates ill-conditioned spectra, is shown to partially compensate for problems due to the nature of analysis of particulate materials.
