天然气 用气相色谱法测定组成和计算相关不确定度 第8部分：用微型热导测定氢、氧、氮、一氧化碳、二氧化碳和C1至C5及C6+的烃类
Application Summary AI generated
This standard specifies a method for determining the concentration of hydrogen, oxygen, nitrogen, carbon monoxide, carbon dioxide, and hydrocarbons from C1 to C5 and C6+ in natural gas using a micro-cell thermal conductivity detector. It is applied in the natural gas industry for quality control, custody transfer, and compositional analysis, ensuring accurate measurement of trace and major components for pipeline gas and LNG. The standard also provides guidance on calculating the associated uncertainty of the gas chromatography results.
