Multielement d-c Plasma Emission Spectrometric Analysis of Steels and Irons

Source

Simultaneous multielement trace analysis of steel alloys by d-c plasma emission echelle grating spectroscopy (DCP) has been developed using a single-matrix synthetic standard. Emission lines free from spectral interference have been selected by scanning wavelength regions, and their analytical capabilities have been characterized. Background shifts and enhancement effects were overcome by using an iron matrix synthetic standard. Sixteen elements at concentrations of less than 1 weight percent were simultaneously analyzed in up to 60 certified steel alloy samples. The DCP results compared favorably with the certified values and were accurate to within 10 percent for most elements. The precision of the analyses, indicated by the standard deviation of at least four repeat runs, was less than 10 percent.
