Tetrahydrophene is an organic compound with the chemical formula C4H8S. It is mainly used as an odorant for fuel gases such as city gas, liquefied petroleum gas, and natural liquefied gas. It can also be used as a raw material for pharmaceuticals and pesticides.
This document specifies the principle, reagents and materials, instruments, sampling, measurement steps, calculation methods, and precision requirements for online determination of the content of odorant tetrahydrothiophene in natural gas using a thermal conductivity detector portable gas chromatograph.
This document is applicable for the determination of tetrahydrothiophene content in natural gas, with a measurement range of 5 mg/m3 to 200 mg/m3.
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 dedicated capillary chromatography column and a hydrogen flame detector for detection, and the working curve of tetrahydrothiophene is plotted. The lowest detection limit of tetrahydrothiophene can reach 0.5mg · m-3. After 6 repeated determinations, 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
