Combinación de sistemas de flujo de baja y alta presion para la determinacion de Mg, Ca y Sr en salmueras por espectrofotometria de absorcion atomica con llama
“…With a conventional nebulizer, viscosity effects meant that concentrations of oil higher than 70% (w/w) could not be introduced. Neira and Povenda described (in Portuguese) a procedure 102 in which hydraulic high-pressure nebulization was used following low-pressure solid-phase extraction of the ion-pairs with tetrabutylammonium ions of the Ca, Mg and Sr complexes with xylenol orange. Todoli and Mermet evaluated 103 a direct injection high-efficiency (DIHEN) nebulizer for ICP-OES.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
