Thermal Desorption - which tube and which adsorbent do I need?

Supelco produces a comprehensive selection of adsorbent tubes. Selection of the proper adsorbent(s) is critical to achieving the best results for a thermal desorption application. An ideal adsorbent tube, such as Carbotrap tubes, will trap and retain compounds of interest for the entire sampling period, then allow total analyte desorption without thermal decomposition. The rate of release should be as rapid as possible, to minimize analysis time and provide the most efficient separation. Stable adsorbents ensure the best detection limits by minimizing the possibility of breakdown products interfering with quantification.

This volume will help in deciding which thermal desorption tube and adsorbent is best for your application.
