Abstract

The applicability of the microwave-coupled hollow cathode excitation source to the determination of minor elements in metals and alloys was tested in the case of Cu (0.019–0.060%), Fe (0.30–0.34%), Mg (1.29–5.85%), Mn (0.12–0.58%), Ti (0.014–0.042%) and Zn (0.012–0.040%). The combined discharge permitted the intensity of analyte spectral lines to be increased, whereas a decrease was observed in background level as well as in the intensity of the carrier gas spectrum. Higher signal-to-noise ratios could thus be obtained without sacrificing any of the properties possessed by the hollow cathode discharge.
