1 Scope

YS/T of the provisions of section 710 of the method for the determination of the sulfur content of cobalt oxide. This section applies to the determination of sulfur in the amount of cobalt oxide. Measurement range. 0.0050% to 0.100%.

2 Method summary

In the presence of flux, high-frequency induction furnace and the oxygen flow, so that the sample burned at high temperatures, to generate sulfur dioxide gas into the red External absorption cell, after which the instrument automatically measure the absorption of infrared energy to calculate and display the results.
