Coherent forward scattering technique to determine copper in steels, zinc and tin

Abstract

Coherent forward scattering spectroscopy having the Voigt configuration was applied in the determination of copper in steels, zinc and tin. Copper (0.0005-0.2%) in these metals could be determined without preconcentration procedure. The relative standard deviations were 4.4% for 0.0035% copper and 7.1% for 0.067% copper in steel. The reproducibility of calibration curves for copper in steels (log-log plotting with a slope of about two) was about 18% and the limit of detection was about 0.4 ± 0.07 ng/10 μl. © 1981.
