| Abstract: | A method for simultaneous determination of carbon and sulfur in coal samples by HFIR C/S analyzer is described in this paper. The proposed method provides a wide concentration range for carbon (w=0%～80%) and sulfur (w=0%～2%). The method has been verified by the determination of carbon and sulfur in standard reference coal samples. The results are in agreement with certified values with precision (n=8) of<1.7% RSD for carbon and <1.3% RSD for sulfur. |
