Abstract The determination of total sulfur content in natural gas is to transport the on-site natural gas samples to the laboratory through the sampling steel cylinder. The ordinary sampling cylinder is easy to adsorb sulfide, while the passivated sampling cylinder can reduce the adsorption of sulfide. The adsorption of sulfide by passivated and ordinary steel cylinders is analyzed quantitatively by the ultraviolet fluorescence method, and the data are compared. The results show that the passivated sampling cylinder can hardly adsorb the sulfide, and the total sulfur content can be accurately analyzed by using it, while the ordinary sampling cylinder can adsorb the sulfide to a certain extent and follow certain adsorption kinetics, which makes the sample no longer representative, and the total sulfur content cannot be accurately analyzed by using the passivation sampling cylinder. It is recommended to use passivated cylinder for total sulfur content analysis.

Key words： metrology natural gas total sulfur ultraviolet fluorescence sampling steel cylinder passivated
