Total sulfur in coal is one of the important indicators for evaluating coal quality. In order to effectively and economically utilize coal resources, it is necessary to comprehensively understand the total sulfur content in coal. Based on the principle of coulometric titration and the consideration of man-machine material loop measurement, this paper deeply explores the main factors affecting the measurement accuracy, aiming to significantly improve the accuracy of total sulfur determination through systematic analysis of the influence of various factors on the detection and standardization of the correct use, inspection and maintenance of the instrument.
