General Method

The application of the vacuum-cup electrode to the spectrographs analysis of solutions of refractory-metal alloys is described. Both citric and oxalic acids in 5% sulfuric acid solution served as suitable completing agents. The absence of interelement effects is demonstrated. Alternate sets of excitation parameters and variation of sample weight and aliquot sizes permit application of the technique to a broad range of element concentrations. Typical coefficients of variation of results obtained by the method are between 3% and 4%.
