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

Advances in atomic emission, absorption and fluorescence spectrometry and related techniques

“…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.…”
