The adsorption performance of Tenax-TA adsorption tube for benzene series in a closed environment. Methods According to the "Indoor Air Quality Standards" total volatile organic compounds determination method and the US EPA TO-17 standard method, the prepared benzene series standard gas was sampled with Tenax-TA adsorption tube, and the retention time was qualitatively and the peak area was quantified. Results The relative standard deviation of the determination of benzene series by this method was between 4.50% and 9.51%. The minimum detectable concentrations of benzene, toluene, p-xylene and o-xylene were 0.04, 0.65, 0.50 and 1.60μg/m3, respectively. When the sampling volume is not more than 3 L, the Tenax-TA sampling tube does not penetrate, and the benzene series can be stored for 40 days at room temperature after adsorption through the Tenax-TA tube. Conclusion Tenax-TA adsorption tube has good adsorption performance for benzene series, and the equipment is simple, the sample storage time is long, and it is suitable for gas collection in some special environments.

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. established an analysis method for low-concentration benzene series in ambient air, and studied the best desorption conditions and analysis conditions. The method used Tenax TA adsorption/secondary thermal desorption/capillary gas chromatography. Results The relative standard deviation of this method for the determination of benzene series is between 4.30% and 10.81%, which has good reproducibility. The recovery rate of standard addition of benzene series is greater than 94%. Benzene, toluene, p-xylene, o-xylene The lowest detectable concentrations are 0.09, 0.12, 0.23, 0.26 μg/m3, respectively. Conclusion This method is suitable for the determination of low-concentration benzene series in ambient air.
