Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. is studying the adsorption performance of Tenax TA adsorption tubes for benzene derivatives in a closed environment. According to the determination method of total volatile organic compounds in the Indoor Air Quality Standards and the US EPA TO-17 standard method, the prepared benzene based standard gas was sampled using a Tenax TA adsorption tube for qualitative retention time and quantitative peak area. The relative standard deviation of this method for the determination of benzene derivatives was between 4.50% and 9.51%. The detected concentrations of benzene, jia benzene, para di jia benzene, and ortho di jia benzene were 0.04, 0.65, 0.50, and 1.60 μ g/m3, respectively. When the sampling volume is not greater than 3 L, there is no penetration phenomenon in the Tenax TA sampling tube, and the benzene series can be stored at room temperature for 40 days after adsorption sampling through the Tenax TA tube. Tenax TA adsorption tubes have good adsorption performance for benzene derivatives, and the equipment is simple with long sample storage time, making them suitable for gas collection in some special environments.
