Based on the introduction of high frequency induction infrared absorption,this paper studies its application on the sulphur content determination in tungsten concentrate.

Rapid determination of sulfur in barium carbonate by high frequency-infrared absorption method;

The method of high frequency IR-absorption spectrometry used to determine the sulfur in antimony sulfide concentrates and antimony oxide concentrates is introduced in this article.

Combining with practice, C,S in silicomanganese were determined by IR absorption method with calibration of different reference materials of iron and using regenerated crucibleThe analytical results were satisfactory.
