ActiveNatural gas - Determination of composition with defined uncertainty by gas chromatography - Part 6: Determination of hydrogen helium oxygen nitrogen carbon dioxide and C1 to C8 hydrocarbons using three capillary columns
天然气 在一定不确定度下用气相色谱法测定组成 第6部分：用三根毛细管色谱柱测定氢、氦、氧、氮、二氧化碳和C1至C8的烃类
Application Summary AI generated
This standard specifies a gas chromatography method using three capillary columns to determine the concentration of hydrogen, helium, oxygen, nitrogen, carbon dioxide, and hydrocarbons from C1 to C8 in natural gas. It is applied in the natural gas industry for custody transfer, quality control, and compositional analysis where defined measurement uncertainty is required. The method ensures accurate characterization of gas composition for pipeline transport, liquefied natural gas processing, and energy trading.
