Abstract

Laser induced breakdown spectrometry (LIBS) is a simultaneous multi elemental methods that enables a direct and fast analysis (0.5 min) of solid, liquid and gaseous samples; it shows a microanalytical capability since allows analysis of a very low sample mass size (<100ug) and for this reason is a quasi-nondestructive method; it allows an on-site and remote analysis since portable instruments are available. Despite all those advantages, LIBS is still young in terms of analytical application in real sample analysis and shows many challenges that have to be understood and overcome. The microanalytical capability associated with the sample heterogeneity commonly results in low precision results. In the case of solid samples, particle sizes affect the atomization efficiency and together with the complex nature of sample-laser interaction causes a strong and undesirable chemical interference, making the quantitative analysis an issue and has been considered the "Achilles' heel" of the method. In this context, evaluating instrumental parameters, as well as sample parameters associated with the proposing of appropriate calibration strategies, are imperative to enable quantitative analysis in complex samples. This project proposes join effort of three research groups in ordem to make LIBS feasible at least in three different applications: analysis of refractory samples since LIBS allows direct solid samples analysis; elemental mapping in food samples due to LIBS microanalytical capability and liquid samples analysis (water, oil and lubricant) after proposing analyte preconcentration strategies.
