TD-GCMS - Thermo-Desorption Gas Chromatography Mass Spectrometry

The so called Thermo-Desorption usually is a two-step sample injection method for GC-MS. In the first step an adsorbent material (e.g. TENAX-TA) is utilized to collect, and if necessary concentrate, volatile organic compounds (VOCs).

In the second step the adsorbent is heated in the thermo desorber oven, causing the adsorbent to release the collected sample (VOCs) into to GC-MS for separation, identification and quantification.


  • Analysis of VOCs released during thermal processes
  • Screening of additives and plasticizers in polymeric materials
  • Testing of materials and devices for outgassing sensitive environments, e.g. clean room
  • Determination of residual components, e.g. solvents in packaging materials or photo initiators in solder resist
  • Analysis of general outgassing or odor problems.
