GL Sciences / Tenax

GL Sciences-Tenax

The Tenax material consists of a porous polymer based on 2,6-diphenyl-p-phenylene oxide.

 

TenaxTA was developed to minimise ghost peaks caused by aromatic hydrocarbons and halogenated compounds. This material can be used both in a packed column and as a trapping adsorbent for organic volatile and semi-volatile compounds.

 

Tenax GR is made from the same polymer as Tenax TA, but 23% 0.5µm graphitic carbon has been added in the polymerisation process. The addition of graphitic carbon maintains the same hydrophobicity and thermal stability, but results in a higher breakthrough volume than conventional Tenax TA.
