Abstract
This report covers the investigation of eight factors and their effects on the reproducibility of intensity ratios of spectral lines when the high voltage alternating-current arc is used as a source of excitation for quantitative spectrochemical analysis. The factors considered are photometry, weight of sample on the electrode, preburn time, exposure time, electrode separation, arc current, inductance, and anion-cation effect. Sodium hydroxide, sodium chloride, and calcium carbonate are employed for the work on the first seven factors. In the investigation of the anion-cation effect, eight inorganic salts are used. In conclusion there is a short discussion about data taken by a direct reading technique employing multiplier photo-tubes. Here an attempt is made to study short period variation in intensity ratio rather than the integrated effects produced when using photographic plates.
