Tenax-TA 吸附管在TVOC检测工作

尺寸：长3.5英寸，外径1/4英寸

填料：TENAX-TA，60-80目

外壁材料：不锈钢

Tenax-Ta管在检测空气TVOC含量过程中是不可或缺的吸附管,在检测过程中要反复使用,但它的使用寿命有多长,长时间反复吸附和解吸对检测结果是否会产生影响,通过试验对此进行了简单研究。

浩瀚色谱（山东）应用技术开发有限公司，利用Tenax-TA和活性炭以不同流速吸附苯,并解析。通过回收率、穿透率的比较,认为在一定的流速以内,Tenax-TA吸附解析空气中苯的数值是可以参考的。

Tenax-Ta tube is an indispensable adsorption tube in the process of detecting air TVOC content. It must be used repeatedly during the detection process, but how long its service life is and whether repeated adsorption and desorption for a long time will affect the test results. A simple study was carried out through experiments.

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. uses Tenax-TA and activated carbon to adsorb benzene at different flow rates and analyze. Through the comparison of recovery rate and penetration rate, it is believed that within a certain flow rate, the value of benzene in the air adsorbed and resolved by Tenax-TA can be used as a reference.
