GC-790 capillary column gas chromatography for the determination of tetrahydrothiophene in natural gas

Detailed information on the determination of tetrahydrothiophene in natural gas by GC-790 capillary column gas chromatography:

Tetrahydrothiophene is an odorant in natural gas, which has a strong unpleasant odor and produces a stable odor that is not easily emitted. It can be smelled in the presence of 0.01mg · m-3 in the air

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has established an analysis method for tetrahydrothiophene in natural gas using gas chromatography. The method uses a 14% cyanopropylphenyl-86% methylpolysiloxane capillary chromatography column and a hydrogen flame detector for detection. The working curve of tetrahydrothiophene is drawn, and the low detection limit of tetrahydrothiophene can reach 0.5mg · m-3. After 6 repeated measurements, The relative standard deviation is less than 0.02%. This method has been used for the determination of tetrahydrothiophene in natural gas and has achieved satisfactory results
