Abstract
In this paper the use of Laser Induced Breakdown Spectroscopy as tool for quantitative elemental analysis of soils is considered. Namely the influence of plasma temperature on quantitative measurements is discussed and a single theoretical approach is used to model the plasma generation. It is shown that the estimation of temperature in the laser induced plasma and its inclusion in a model for line emissions allows for a substantial reduction of the matrix effect, formerly recognized as the main factor reducing the possibilities of quantitative applications. To illustrate the benefits of the proposed correction, some experimental results, obtained with the use some reference samples soils, are presented.
