Tenax化学名为聚2,6-二苯基对苯醚,是一种高分子线性聚合物,早由荷兰的AKZO实验室合成,并由荷兰的Buchem B.V.公司注册为Tenax?。Tenax系列产品已发展了三代即Tenax GC、Tenax TA和Tenax GR。Tenax GC是代产品,初开发做色谱柱填料,其后应用范围扩大,用于采集样品和富集样品等领域;随着研究的发展,Tenax GC逐渐被新一代产品Tenax TA所替代,Tenax TA比Tenax GC所含杂质少,纯度高且不易流失,使得Tenax的应用广泛;Tenax GR是新一代Tenax产品,其中包含了23%的石墨化碳黑,两者不是简单的混合在一起,而是由石墨化碳黑和Tenax聚合物共沉淀而得。

现行标准《民用建筑工程室内环境污染控制规范》GB50325-2001(2006年版)(以下简称《规范》)中规定,苯和TVOC分别采用不同的方法来进行检测。空气中苯的采样采用活性炭吸附剂,采样10L,热解吸或CS2溶剂解吸直接进样色谱分析或手工进样色谱分析;TVOC的检测采用Tenax-TA吸附剂,采样1～5L(2001年版采样体积为10L),热解吸直接进样或手工进样色谱分析。
滕州市浩瀚色谱仪器技术服务有限公司，通过改变Tenax--TA吸附剂的量、采样的温度、样品的采集体积等条件，研究这些条件的改变对Tenax--TA对苯及TVOC的吸附性能的影响。实验表明，用Tenax--TA吸附剂在合适的条件下能同时准确定量空气中的苯及TVOC。

Tenax's chemical name is poly(2,6-diphenyl-p-phenylene ether), a polymer linear polymer originally synthesized by the AKZO laboratory in the Netherlands and registered as Tenax® by Buchem B.V. of the Netherlands. Tenax series products have been developed for three generations, Tenax GC, Tenax TA and Tenax GR. Tenax GC is the first generation product, originally developed as a column packing material, and its application range has been expanded to collect samples and enrich samples. As the research progresses, the Tenax GC is gradually replaced by the new generation product Tenax TA. Tenax TA has less impurities, higher purity and less loss than Tenax GC, making Tenax more widely used; Tenax GR is a new generation of Tenax products, which contain 23% graphitized carbon black, which are not simply mixed together. Instead, it is obtained by coprecipitation of graphitized carbon black and Tenax polymer.

The current national standard "Code for Indoor Environmental Pollution Control of Civil Building Engineering" GB50325-2001 (2006 edition) (hereinafter referred to as "Specifications") stipulates that benzene and TVOC are respectively tested by different methods. The sampling of benzene in the air is performed by using activated carbon adsorbent, sampling 10L, thermal desorption or CS2 solvent desorption direct injection chromatography or manual injection chromatography; TVOC detection using Tenax-TA adsorbent, sampling 1 ~ 5L (2001 version sampling Volume 10L), thermal desorption direct injection or manual injection chromatography.
Tengzhou Haohao Chromatography Instrument Technology Service Co., Ltd. studied the adsorption properties of Tenax-TA on benzene and TVOC by changing the amount of Tenax-TA adsorbent, sampling temperature, sample collection volume and other conditions. influences. Experiments show that the Benax-TA adsorbent can accurately quantify benzene and TVOC in the air under suitable conditions.
