天然气 加臭剂四氢噻吩含量的测定 在线取样气相色谱法
Application Summary AI generated
This standard specifies the on-line sampling gas chromatography method for determining the content of tetrahydrothiophene, a common odorant added to natural gas for leak detection. It is applied in natural gas production, transmission, and distribution systems to monitor odorant concentration in real time, ensuring safety compliance and accurate odorization levels. The method is used by gas utilities, pipeline operators, and quality control laboratories for continuous, automated analysis without manual sample handling.
