Through the accurate determination of the content of tetrahydrothiophene in the activated carbon adsorption tube, we can monitor the material leakage or loss that may occur in the production process in real time, so as to take corresponding measures in time to avoid the waste of resources and the decline of production efficiency. In addition, the accurate determination of the content of tetrahydrothiophene also provides an important basis for the optimization of the production process, which helps us to further improve the production process and improve product quality and yield. This paper describes in detail the method of determining the content of tetrahydrothiophene in the standard activated carbon adsorption tube using GC-4100 gas chromatography. The method not only has good repeatability, but also has high accuracy, providing a practical reference for relevant practitioners. Attachment download
