　　This document specifies the determination principle, reagents and materials, instruments and equipment, test steps, result calculation, precision, and test report of the gas chromatography method for crude benzene content in coal gas.

　　This document is applicable to the determination of crude benzene content in coke oven gas generated during coking production.

　　Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has established a new method for determining crude benzene in coal gas. The gas sample is directly taken with a syringe, and the retention time is used for qualitative analysis. The external standard method is multiplied by an empirical coefficient for quantitative analysis. Compared with traditional distillation methods, the analysis time is shortened from 5-6 hours to 15-20 minutes, which has the advantages of less sample volume, simple operation, and accurate results.
