“…In LIBS, the predictor is usually the intensity or the peak area of the relevant atomic or ionic line [22], or even the one of the relevant molecular lines [23]. Moreover, in order to overcome some experimental effects, it is common to prefer the ratio of two spectral lines [24] as a kind of normalization.…”

International audienceThis paper presents a review on the analytical results obtained by laser-induced breakdown spectroscopy (LIBS). In the first part, results on identification and classification of samples are presented including the risk of misclas-sification, and in the second part, results on concentration measurement based on calibration are accompanied with significant figures of merit including the concept of accuracy. Both univariate and multivariate approaches are discussed with special emphasis on the methodology, the way of presenting the results and the assessment of the methods. Finally, good practices are proposed for both classification and concentration measurement

“…Many techniques such as X-ray fluorescence (XRF) [4], inductively coupled plasma-mass spectrometry (ICP-MS) [4], neutron activation [6], and LIBS [7,[10][11][12][13][14][15] have been used for coal and coal ash elemental composition analysis. We, however, use the LIBS technique because this is the fast, simple, reagent-free, low-ppm level detection technique for many different situations.…”

a b s t r a c tWe reported our preliminary results on the use of laser-induced breakdown spectroscopy to analyze the rare earth elements contained in ash samples from Powder River Basin sub-bituminous coal (PRB-coal). We have identified many elements in the lanthanide series (cerium, europium, holmium, lanthanum, lutetium, praseodymium, promethium, samarium, terbium, ytterbium) and some elements in the actinide series (actinium, thorium, uranium, plutonium, berkelium, californium) in the ash samples. In addition, various metals were also seen to present in the ash samples.Published by Elsevier Ltd.

“…An interesting approach to overcoming the particle size effect and heterogeneity due to low sample mass, achieving matrix matching between samples and the calibration RM, is the use of a fusion process for sample preparation (Stankova et al 2010 andJantzi et al 2016). Fusion is a heterogeneous reaction performed at high temperatures between samples and reference materials with fluxing agents (Leite et al 2011, Tian et al 2015 such as lithium metaborate, lithium tetraborate, lithium carbonate, boric acid, sodium hydroxide, sodium carbonate or combinations of these reagents (Intima et al 2009), resulting in a more homogeneous and less refractory product.…”

Due to matrix interference and sample particle size effects, some of the most important and difficult issues in laser‐induced breakdown spectroscopy (LIBS) analysis are the calibration and quantitative measurement of a complex matrix. This study proposes the use of borate fusion as an alternative sample preparation procedure for the quantitative measurement of Al, Fe, Si and Ti in bauxite by LIBS. Analytical calibration curves were made using bauxite certified reference materials (CRM), and the precision and accuracy of the methods were evaluated by analysing an additional bauxite CRM, using two different approaches: pressed powder pellets and fused glass beads. The borate fusion method was the most suitable sample preparation technique, since particle size effects and matrix interference could be minimised, obtaining better linearity on the analytical calibration curves (r2), and more accurate and more precise results for bauxite analysis.
