一般說明
Porous polymer sorbents are inert, hydrophobic with large surface area. These sorbents retain volatile compounds, water and solvent vapours. This is advantageous if sample is from atmosphere with high content of water and solvent vapours. They are most suitable for trapping toxic agents with high molecular weight and non-volatile substances like pesticides. They are also suitable for sampling many compounds sorbed by charcoal and silica gel. Tenax® TA is basically synthetically produced polymer based on the 2,6-diphenylene oxide is more efficient in the recovery of higher molecular weight compounds. It is suitable for both polar and nonpolar analytes.
基于2,6-二苯基-对苯醚的Tenax多孔聚合物广泛用作空气收集和吹扫捕集器应用中的吸附剂。与其他多孔聚合物相比，其独特的结构提供了交替和理想的吸附/解吸特性。

應用
Tenax® TA is suitable as an adsorbent used for air sampling, it was examined for its potential to form artifacts with Ozone at environmental concentrations, which was then quantitatively analysed using GC-MS analysis. It is also used in adsorbent columns suitable for recovering volatile compounds analysed by GC.
