GB/T 11060.4-2017 focuses on the determination of sulfur compounds in natural gas, and the total sulfur content is measured by oxidation micro-Coulometry. It describes the principle of converting sulfur through oxidation reaction and measuring it by electrochemistry. The performance and accuracy of equipment such as oxidation micro-Coulometry are required, and the natural gas sampling, pretreatment process, and specific measurement steps on the instrument are specified in detail, and the data processing and result expression are standardized. This standard provides a unified method for accurately determining the total sulfur content of natural gas, which is of great significance for ensuring the mass of natural gas, controlling the risk of sulfur content and related industrial applications.
