ActiveNatural gas—Determination of composition and associated uncertainty by gas chromatography—Part 7:Rapid determination of helium content using two packed columns
天然气 用气相色谱法测定组成和计算相关不确定度 第7部分：用两根填充柱快速测定氦气含量
Application Summary AI generated
This standard specifies a gas chromatography method using two packed columns for the rapid determination of helium content in natural gas. It is applied in the natural gas industry for quality control, custody transfer, and process monitoring where fast and accurate helium measurement is required. The method is particularly relevant for gas processing plants and pipeline operations that need to assess helium concentration for commercial or operational purposes.
