CDS Analytical Thermal Desorption

  • Description

Thermal Desorption

Thermal desorption encompasses two primary functions; sample collection/concentration, and transfer to a detector. Most applications involve investigating air collected on sorbent tubes and/ or volatile organics that are evolved from solids. The process is flexible and convenient and based on EPA methods TO-17, ASTM D6196, NIOSH 2459 and MDHS 72.

Key features:

Thermal desorption uses heat, (instead of solvent extraction), to release organic compounds from the adsorbent and transfer the entire collected sample to a gas chromatograph for analysis. This eliminates extraction time, (typically 12-24 hours), a solvent peak in the chromatogram (which can mask compounds of interest), and waste solvent disposal, an increasing expense in many labs.
