GB 17820对硫化物气体标准物质的影响探讨
Influence of GB 17820 on the preparation of sulfur compounds reference gas
摘要
Abstract
Mandatory standard GB 17820-2018 Natural Gas has been published. The influence of this standard on the needs of sulfur contained reference gas is discussed. With the huge change in the natural gas quality control field，the traceability of worldwide H2S and SO2 reference gas is analyzed to carry out the demand to research and produce such reference gas. According to this mandatory standard，natural gas entering long distance pipeline should has no more than 6 mg/m3 H2S，the analysis methods on H2S in natural gas with such concentration is also listed in this standard. In order to get accurate analytic results，not only the analytic method is needed，but also the traceability is required. In other word，proper reference gas mixture is required to achieve good traceability and accuracy of the testing result in order to ensure the quality of the pipeline transmitted natural gas.关键词
