Evaluation of Uncertainty in Measurement of Sulfur Content in Dolomite by Infrared Carbon Sulfur Analyzer

The mathematical model of uncertainty in the determination of sulfur content in dolomite by infrared carbon sulfur analyzer was established. Through the calculation and analysis of the uncertainty component, the uncertainty of the synthetic standard and the extension of the detection method were obtained. The results showed that the method is of high reliability and is suitable for the determination of sulfur content in dolomite.
