Simultaneous determination of some hydride forming elements (Sb, Sn and Pb) in soft solder alloys using a coupling system of flow injection analysis with hydride generation and Fourier transform infrared spectrometry using multiple linear regression

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.
