Abstract

With the expanding applications of carbon materials in primary aluminum production, new energy batteries, and other fields, their sulfur content, as a critical quality indicator, directly influences product performance and environmental compliance. Traditional methods for sulfur content determination are constrained by factors such as sample decomposition efficiency, interfering elements, and instrument sensitivity, making it challenging to meet the demands for high-precision detection. This paper focuses on exploring pathways to enhance the accuracy of sulfur content analysis in carbon materials. By integrating advanced technologies such as the oxygen bomb combustion method and high-frequency infrared carbon-sulfur analyzers, research is conducted across five aspects: sample pretreatment, combustion efficiency optimization, instrument calibration, interference elimination, and standardized operating procedures. It is proposed that measures such as optimizing combustion conditions, improving flux formulations, and establishing linear calibration models can significantly enhance the repeatability and accuracy of detection results, providing technical support for quality control of carbon materials.
