MilliporeSigma™ Supelco™ Tenax™ Porous Polymer Adsorbent, Matrix Tenax TA, 80-100 mesh

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.
