Thermal desorber for gas chromatography
TDS
GERSTEL
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 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, emissions from materials that are used indoors in buildings or in automobiles, semiconductors, polymers and packaging.
The TDS 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 TDS-A Autosampler, the TDS becomes a fully automated thermal desorption system capable of unattended analysis of up to 20 samples.
The MAESTRO software combined with the Agilent ChemStation controls the complete process from sample introduction through thermal desorption to GC/MS analysis with one method and one sequence table ensuring efficient and error-free operation.
