Carbonate rocks, mainly limestone and dolostone, have made up 10% to 15% of sedimentary rocks in the Earth. Geochemical contents of carbonate rocks could reflect a series of key geological information of ancient environment, such as temperature, precipitation, salinity and geologic event. Stand-off LIBS provides an approach to rapidly, accurately and nondestructively determine the elemental concentrations...
In this study, a particle swarm optimization (PSO) algorithm was implemented to quantitatively analyze the Lead (Pb) concentration in water. Thirty-five samples with different concentrations of Pb(NO3)2 were detected by laser-induced breakdown spectroscopy (LIBS). The strong spectral line of 405.78 nm was selected as the analytical line. The PSO algorithm was created, trained and tested by IPb. The...
