GB/T 19207-2003 in English

《GB/T 19207-2003天然气中总硫的测定 氢解-速率计比色法》由TC244（全国天然气标准化技术委员会）归口，主管部门为国家标准化管理委员会。
本标准规定了用氢解－速率计比色法测定天然气中总硫含量的试验方法。本标准适用于天然气中总硫含量的测定，测定范围为0.001×10-6～20×10-6，并且可通过稀释剂将测定范围扩展到较高浓度。本标准也可以作为精制产品如丙烷、丁烷、乙烷、乙烯质量控制的分析手段。

Scope

This standard specifies the test method for the determination of total sulfur content in natural gas by hydrogenolysis-rate meter colorimetry. This standard is applicable to the determination of the total sulfur content in natural gas, and the determination range is (volume fraction φ) 0.001×10^-6～20×10^-6, and the measurement range can be extended to a larger range by dilution High concentration. This standard can also be used as an analysis method for quality control of refined products such as propane, butane, ethane, and ethylene. This standard does not address all safety issues related to its application. Before using this standard, it is the user's responsibility to formulate corresponding safety and health measures, and to clarify the applicable scope of its limitations.
