浩瀚Tenax-TA采样管填充柱6*90

浩瀚色谱（山东）应用技术开发有限公司探讨Tenax-TA吸附管对密闭环境中苯系物的吸附性能。方法依据《室内空气质量标准》总挥发性有机物的测定方法和美国EPA TO-17标准方法,用Tenax-TA吸附管对配制的苯系物标准气体进行采样,以保留时间定性,峰面积定量。结果该方法对苯系物测定的相对标准偏差在4.50%～9.51%之间,苯、甲苯、对二甲苯、邻二甲苯的*低检出浓度分别为0.04,0.65,0.50和1.60μg/m3。当采样体积不大于3 L时,Tenax-TA采样管没有穿透现象发生,苯系物通过Tenax-TA管吸附采样后在室温下可以保存40 d。结论 Tenax-TA吸附管对苯系物具有良好的吸附性能,而且设备简单,样品保存时间长,适合于一些特殊环境中气体的采集。

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. discussed the adsorption performance of Tenax-TA adsorption tube for benzene series in a closed environment. Methods According to the determination method of total volatile organic compounds in "Indoor Air Quality Standard" and the US EPA TO-17 standard method, the prepared benzene series standard gas was sampled by Tenax-TA adsorption tube, and the retention time was used for qualitative determination and peak area for quantitative determination. Results The relative standard deviation of this method for the determination of benzene series compounds was between 4.50% and 9.51%, and the minimum detectable concentrations of benzene, toluene, p-xylene and o-xylene were 0.04, 0.65, 0.50 and 1.60 μg/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 at room temperature for 40 d after being adsorbed and sampled by the Tenax-TA tube. Conclusion Tenax-TA adsorption tube has good adsorption performance for benzene series, and the equipment is simple and the sample storage time is long, which is suitable for gas collection in some special environments.
