Abstract:

Eighteen elements are determined in beryllium from 5 to 1000 ppm by a dc-arc method. Samples are dissolved in hydrochloric acid, converted thermally to beryllium oxide, then mixed with graphite and barium carbonate for determining calcium, mixed with cupric oxide for determining boron and molybdenum, and mixed with graphite and germanium oxide for determining the other 15 elements. Spectral transmittances of analytical and internal standard lines are converted to relative-intensity ratios which are plotted against concentrations of standards to from curves from which concentrations of impurities are read.
