General description

Tenax porous polymers, based on 2,6-diphenyl-p-phenylene oxide, is widely used as an adsorbent in both air collection and purge trap applications. Its unique structure provides alternate and desirable adsorption/desorption characteristics compared to other porous polymers.

Other Notes

The optimal temperature for Tenax porous polymers depends on the application. For example, thermal desorption unit (TDU) tubes are typically desorbed at 300 °C, and purge traps containing Tenax typically use a 180 °C desorption temperature. For assistance in determining the proper temperature for your application, contact Technical Service at techservice@sial.com


Tenax GR is a composite material containing 70% Tenax TA and 30% graphite carbon.
