GERSTEL Thermal Desorption System

The GERSTEL Thermal Desorption System TDS 3 is a flexible multi-functional system for highly sensitive determination of volatile and semi-volatile organic compounds (VOCs and SVOCs) that have been trapped on adsorbent tubes or on GERSTEL Twisters.

The TDS 3 is also frequently used for direct thermal extraction and determination of VOCs and SVOCs from solids without sample preparation. Application examples are natural products, flavor and fragrance, emissions from materials that are used indoor in buildings or in automobiles, semiconductors, polymers and packaging.

The TDS 3 is mounted on top of a Cooled Injection System CIS that is used as a cryotrap, focusing and concentrating the components to be determined, and then transferring them to the capillary column in split- or splitless mode without analyte discrimination or loss of analytes.

With the addition of the GERSTEL TDS A2, the TDS 3 becomes a fully automated thermal desorption system capable of unattended analysis of up to 20 samples.
The GERSTEL Online TDS G enables whole-air sampling as well as direct sampling of gas streams for continuous on-line monitoring.
