quantitative emission spectrometry

gold alloys

An emission spectrometric method is described for the determination of major constituents in metal samples. The metal sample is made the hollow-cathode of a demountable emission source. Use of the hollow-cathode discharge permits intensity measurements of the analytical lines (resonance lines) to be made with high signal-to-noise ratio. For ultimate precision and accuracy, such as is required in the determination of gold in gold alloys, internal standardization is also necessary. The precision is approximately 0.03% (w/w) (standard deviation) anal the accuracy is 0.03% (w/w).
