天然气 在一定不确定度下用气相色谱法测定组成 第3部分：用两根填充柱测定氢、氦、氧、氮、二氧化碳和直至C8的烃类
Application Summary AI generated
This standard specifies a gas chromatography method using two packed columns to determine the concentration of hydrogen, helium, oxygen, nitrogen, carbon dioxide, and hydrocarbons up to C8 in natural gas. It is applied in the natural gas industry for quality control, custody transfer, and compositional analysis to ensure accurate measurement with defined uncertainty. The method is particularly relevant for gas processing plants, pipeline operators, and testing laboratories requiring reliable component quantification.
