Tenax化學(xué)名為聚2,6-二苯基對(duì)苯醚,是一種高分子線性聚合物,早由荷蘭的AKZO實(shí)驗(yàn)室合成,并由荷蘭的Buchem B.V.公司注冊(cè)為T(mén)enax?。Tenax系列產(chǎn)品已發(fā)展了三代即Tenax GC、Tenax TA和Tenax GR。Tenax GC是代產(chǎn)品,初開(kāi)發(fā)做色譜柱填料,其后應(yīng)用范圍擴(kuò)大,用于采集樣品和富集樣品等領(lǐng)域;隨著研究的發(fā)展,Tenax GC逐漸被新一代產(chǎn)品Tenax TA所替代,Tenax TA比Tenax GC所含雜質(zhì)少,純度高且不易流失,使得Tenax的應(yīng)用廣泛;Tenax GR是新一代Tenax產(chǎn)品,其中包含了23%的石墨化碳黑,兩者不是簡(jiǎn)單的混合在一起,而是由石墨化碳黑和Tenax聚合物共沉淀而得。

現(xiàn)行標(biāo)準(zhǔn)《民用建筑工程室內(nèi)環(huán)境污染控制規(guī)范》GB50325-2001(2006年版)(以下簡(jiǎn)稱(chēng)《規(guī)范》)中規(guī)定,苯和TVOC分別采用不同的方法來(lái)進(jìn)行檢測(cè)。空氣中苯的采樣采用活性炭吸附劑,采樣10L,熱解吸或CS2溶劑解吸直接進(jìn)樣色譜分析或手工進(jìn)樣色譜分析;TVOC的檢測(cè)采用Tenax-TA吸附劑,采樣1～5L(2001年版采樣體積為10L),熱解吸直接進(jìn)樣或手工進(jìn)樣色譜分析。
滕州市浩瀚色譜儀器技術(shù)服務(wù)有限公司，通過(guò)改變Tenax--TA吸附劑的量、采樣的溫度、樣品的采集體積等條件，研究這些條件的改變對(duì)Tenax--TA對(duì)苯及TVOC的吸附性能的影響。實(shí)驗(yàn)表明，用Tenax--TA吸附劑在合適的條件下能同時(shí)準(zhǔn)確定量空氣中的苯及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.
