Tenax TA , Mesh 20/35, 200nm, 15 g

Tenax TA is composed of a weak acidic porous polymer based on 2,6-diphenyl-p-phenylene oxide. A major cause of ghost peaks would be aromatic hydrocarbons including toluene, xylene, ethylbenzene, etc., contained as impurities in the Tenax GC. In trace analysis, ghost peaks affect resultant data. Tenax TA is designed to minimize ghost peaks and it can be used both as a column packing material and as a trapping adsorbent for organic volatile and semi-volatile compounds.
