Determinación simultánea de algunos elementos formadores de hidruros (Sb, Sn y Pb) en aleaciones de soldaduras blandas, mediante un sistema acoplado de Análisis en Flujo- Generación de Hidruros - Espectrometría Infrarroja de transformada de Fourier utilizando Regresión Lineal Múltiple

Abstract

In this paper the simultaneous determination of hydride forming elements (Sn, Sb and Pb) is proposed by means of a method based on the coupling of a system of flow injection analysis with hydride generation, using infrared spectrometry Fourier transform as a means of detection and the Multiple Linear Regression algorithm for calibrating the analytes under study. The analytical characteristics thrown out by the proposed system were suitable for the determination of the hydrides in samples of alloys used in solders.
