Method Overview After sample digestion treatment, the sample is atomized in a graphite furnace, and the absorbance is measured at 357.9\u202fnm. Within a certain concentration range, the absorbance of chromium is proportional to its content, and quantification is performed by comparison with the standard series. 2. Scope of Application This method applies to sulfur used for various phosphors in the manufacture of television picture tubes and other cathode\u2011ray tubes in the electronics industry. 3.
