Packed column for trace thiophene analysis, HH-SF-I
Benzene is an important chemical raw material used in the production of fine chemical intermediates and organic raw materials. Thiophene is an impurity produced in the production process of pure benzene, which has more negative effects in the process of processing and recycling of pure benzene. If pure maleic anhydride is used to produce maleic anhydride, too high thiophene content will reduce catalyst activity and shorten catalyst life. In the production of cyclohexanone, trace thiophene in the raw material pure benzene will cause cyclohexanone production.
Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd. has developed a special packed column for trace thiophene analysis, HH-SF-I, which has analyzed and determined the trace thiophene in hydrogenated benzene by gas chromatography, and carried out with the traditional spectrophotometric experimental data. Comparison and analysis of precision and small detection limit, found through experiments: Compared with the spectrophotometry method and other gas chromatography methods of the national standard method, the analysis speed is fast, the result accuracy and precision are high, and the low detection concentration of thiophene is 0.01 mg / kg, almost no waste liquid, and meet the product quality testing requirements.
