Tenax-Ta管在檢測空氣TVOC含量過程中是不可或缺的吸附管,在檢測過程中要反復使用,但它的使用壽命有多長,長時間反復吸附和解吸對檢測結(jié)果是否會產(chǎn)生影響,通過試驗對此進行了簡單研究。

浩瀚色譜（山東）應用技術(shù)開發(fā)有限公司，利用Tenax-TA和活性炭以不同流速吸附苯,并解析。通過回收率、穿透率的比較,認為在一定的流速以內(nèi),Tenax-TA吸附解析空氣中苯的數(shù)值是可以參考的。

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.
