| Abstract: | High carbon and low sulfur contained in cast iron were determined by high\|frequency combustion infrared absorption method under the following conditions: the particle size of the sample was less than 0\^290 mm; 1\^5 g graned tungsten and 10 g grained iron were used as fluxes; for carbon analysis, the analysis time was 40 s, the weighed amount of sample was 0\^2 g and the comparison level was 1%; for sulfur analysis, the analysis time was 30 s, the weighed amount of sample was 0\^5 g and the comparison level was 3%. The method features simple analysis procedure and short flowsheet, providing a recovery over 97\^5% and the standard deviation less than 0\^9%. |
