GB/T 8981-2008
AbolishedDetermination of trace hydrogen in gases - Gas chromatographic method
气体中微量氢的测定 气相色谱法
Application Summary AI generated
This standard specifies a gas chromatographic method for determining trace amounts of hydrogen in various industrial gases, such as nitrogen, argon, or air. It is applied in chemical manufacturing, gas production, and quality control laboratories to ensure purity levels meet safety and process requirements. The method is particularly relevant for detecting hydrogen concentrations at parts-per-million (ppm) levels in high-purity gas streams.
