Abstract: Sulfur is very harmful to equipment and environmental health in the production and application of oil products. There are

many ways to determine the sulfur content in petroleum products. This paper introduced ultraviolet fluorescence method and

microcoulomb method, analyzed and compared the two methods from the aspects of measurement principle, important influencing

factors, accuracy and precision. Compared with the microcoulomb method, ultraviolet fluorescence method had better accuracy and

repeatability and fewer influencing factors.
