Characterization of main constituents in potato (Solanum tuberosum) tissues using LIBS

Abstract

LIBS (Laser-Induced Breakdown Spectroscopy) can be a complementary tool to analytical methods commonly employed in environmental studies. This paper presents preliminary results obtained by applying analysis LIBS on potato tissues. Samples were prepared using different parts of this tuber. The major elements have been detected and tissues have been differentiated according to the abundance of nutrients. Although quantitative analysis of components was not performed, the optimal conditions were studied to obtain reliable and repeatable measurements.
