Tenax化學名為聚2,6-二苯基對苯醚,是一種高分子線性聚合物,早由荷蘭的AKZO實驗室合成,并由荷蘭的Buchem
B.V.公司注冊為Tenax?。Tenax系列產品已發展了三代即Tenax GC、Tenax TA和Tenax GR。Tenax
GC是代產品,初開發做色譜柱填料,其后應用范圍擴大,用于采集樣品和富集樣品等領域;隨著研究的發展,Tenax GC逐漸被新一代產品Tenax
TA所替代,Tenax TA比Tenax GC所含雜質少,純度高且不易流失,使得Tenax的應用廣泛;Tenax
GR是新一代Tenax產品,其中包含了23%的石墨化碳黑,兩者不是簡單的混合在一起,而是由石墨化碳黑和Tenax聚合物共沉淀而得。
現行標準《民用建筑工程室內環境污染控制規范》GB50325-2001(2006年版)(以下簡稱《規范》)中規定,苯和TVOC分別采用不同的方法來進行檢測??諝庵斜降牟蓸硬捎?a href="http://www.wuyigiant.com.cn/products/show-7890488.html" target="_blank">活性炭吸附劑,采樣10L,熱解吸或CS2溶劑解吸直接進樣色譜分析或手工進樣色譜分析;TVOC的檢測采用Tenax-TA吸附劑,采樣1~5L(2001年版采樣體積為10L),熱解吸直接進樣或手工進樣色譜分析。
滕州市浩瀚色譜儀器技術服務有限公司,通過改變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Tenax--TA對苯及TVOC的吸附性能的影響。實驗表明,用Tenax--TA吸附劑在合適的條件下能同時準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 co

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.
