WebTenax sample tubes were prepared in the laboratory from 25/40 mesh Tenax TA adsorbent (Alltech Associates). The Tenax was soxhlet extracted for 4-6 hours with metha-nol, dried at 140 °C in a vacuum oven, and stored under vacuum in a desiccator until used. Tenax tubes were pre-pared from 7" X 1/4" O.D. glass tubes packed with 0.25 g of Tenax. WebThe GERSTEL Thermal Desorption System provides unmatched performance for a wide range of applications. Thermal desorption tubes are heated fully and directly, from the sorbent/sample area all the way to the end of the tube, ensuring complete transfer from the thermal desorption tube to the focusing trap with no carryover.
