天然氣加臭作為民用天然氣的重要安全保障措施之一，國家有多項(xiàng)法規(guī)標(biāo)準(zhǔn)對(duì)其進(jìn)行規(guī)定，其中《城鎮(zhèn)燃?xì)庠O(shè)計(jì)規(guī)范》(GB50028—2006)規(guī)定:“無毒燃?xì)庑孤┑娇諝庵?，達(dá)到爆炸下限的20％時(shí)，應(yīng)能察覺。”其條文解釋中進(jìn)一步建議，對(duì)天然氣使用四氫噻吩(THT)進(jìn)行加臭時(shí)，其加臭劑用量不宜小于20mg／Nm3，終端濃度不應(yīng)低于8mg／Nm3。

　　浩瀚色譜（山東）應(yīng)用技術(shù)開發(fā)有限公司，選擇合適的氣相色譜儀和色譜柱，以測(cè)定的準(zhǔn)確性。進(jìn)行氣相色譜分析，面積外標(biāo)法定量，得出四氫噻吩的含量。

　　該方法不僅能夠準(zhǔn)確地測(cè)定天然氣中加臭劑四氫噻吩的含量，而且還具有快速、高效、準(zhǔn)確的特點(diǎn)。

　　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.
