天然气加臭作为民用天然气的重要安全保障措施之一，国家有多项法规标准对其进行规定，其中《城镇燃气设计规范》(GB50028—2006)规定:“无毒燃气泄漏到空气中，达到爆炸下限的20％时，应能察觉。”其条文解释中进一步建议，对天然气使用四氢噻吩(THT)进行加臭时，其加臭剂用量不宜小于20mg／Nm3，终端浓度不应低于8mg／Nm3。

As one of the important safety measures for civilian natural gas, natural gas odorization is regulated by multiple national regulations and standards. Among them, the "Design Code for Urban Gas" (GB50028-2006) stipulates that "when non-toxic gas leaks into the air and reaches 20% of the lower explosive limit, it should be detectable." The article further suggests that when using tetrahydrothiophene (THT) for odorization of natural gas, the amount of odorant should not be less than 20mg/Nm3, The terminal concentration should not be lower than 8mg/Nm3.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. selects suitable gas chromatographs and chromatography columns to ensure the accuracy of the measurement. Perform gas chromatography analysis and quantitative analysis using external standard area method to determine the content of tetrahydrothiophene.
This method not only accurately determines the content of odorant tetrahydrothiophene in natural gas, but also has the characteristics of fast, efficient, and accurate.
