Thermal Desorption System (TDS)

The GERSTEL Thermal Desorption System (TDS) 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 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 fragance, emssions from materials that are used indoors in buildings or in automobiles, semiconductors, polymers and packaging.

Description

The TDS is mounted on top of a Cooled Injection System (CIS) that is used as 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 TDS-A Autosampler, the TDS becomes a fully automated thermal desorption system capable of unattended analysis of up to 20 samples.

The TDS G On-Line version enables whole-air sampling as well as direct sampling of gas streams for continous on-line monitoring.
