LPG瓶装气是居民的重要生活用气,为了保障居民用气的安全,一旦发生燃气泄漏,能够及时发现或警示,国家标准中规定LPG瓶装气必须加臭。根据CJJT 148-2010《城镇燃气加臭技术规程》,加臭剂四氢噻吩、无硫加臭剂、乙硫醇引起警示作用的最小检出量分别为19mg/Nm3、16.7mg/Nm3、7.1mg/Nm3。目前,国内在LPG瓶装气中使用四氢噻吩作为加臭剂。
浩瀚色谱（山东）应用技术开发有限公司，采用气相色谱法，研制出毛细管柱，填充柱，微径柱来测定天然气中四氢噻吩的含量，满足不同仪器用户的选择，效率高。
1.微径柱：外径2mm，1/16, 1.6 内径0.75mm, 1mm
2.填充柱：*1/8，*3；*4
3.毛细管柱：10m，8m，4m，内径0.10,0.20,0.32,0.53
LPG bottled gas is an important household gas for residents. In order to ensure the safety of gas consumption for residents, once a gas leak occurs, it can be detected or warned in a timely manner. The national standard stipulates that LPG bottled gas must be odorized. According to CJJT 148-2010 "Technical Regulations for Odorization of Urban Gas", the minimum detectable levels of warning effects caused by odorants tetrahydrothiophene, sulfur free odorants, and ethanethiol are 19mg/Nm3, 16.7mg/Nm3, and 7.1mg/Nm3, respectively. At present, tetrahydrothiophene is used as an odorant in LPG bottled gas in China.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed capillary columns, packed columns, and micro diameter columns using gas chromatography to determine the content of tetrahydrothiophene in natural gas, meeting the needs of different instrument users with high efficiency.
1. Micro diameter column: outer diameter 2mm, 1/16, 1.6 inner diameter 0.75mm, 1mm
2. Fill columns: * 1/8, * 3* four
3. Capillary columns: 10m, 8m, 4m, inner diameters of 0.10, 0.20, 0.32, 0.53
