Direct determination of lanthanides by LIBS in REE-rich ores: comparison between univariate and DoE based multivariate calibrations with respect to spectral resolution
Timur F. Akhmetzhanov, А. М. Попов
Abstract
The problem of natural lanthanide correlation in ores combined with strong line overlapping is addressed via a DoE based on LHS and multivariate regression. The comparison of the analytical performance of high- and low-resolution spectrometers is presented.
