- Method Overview
After digestion, the sample is atomized in a graphite furnace, and the absorbance is measured at 357.9 nm. Within a certain concentration range, the absorbance value of chromium is proportional to its content, and quantitative analysis is performed by comparison with the standard series.
- Scope of Application
Sulfur used for various phosphors in the manufacture of TV picture tubes and other cathode ray tubes in the electronics industry.
