Thermal desorption is a technique that simplifies and speeds a wide range of gas chromatography (GC) applications, including indoor and outdoor air monitoring, analysis of outgassing from semiconductor materials, polymers, upholstery and furnishings, packaging, pharmaceuticals and analysis of flavors and fragrances.
As the undisputed market leader in GC sample handling, we took the next step to offer you even more benefits for your lab. PerkinElmer now offers a family of five different TurboMatrix™ Thermal Desorber (TD) models in both single-tube and automated 50-sample configurations:

Thermal Desorption Unit TDU
The worlds most flexible Thermal Desorption Instrument
The Thermal Desorption Unit (TDU) is a flexible automated solution for thermal desorption and thermal extraction.
Several techniques are supported by the TDU:
- Stir Bar Sorptive Extraction (SBSE) using the GERSTEL Twister®
- Dynamic Headspace (DHS) based on standard headspace vials
- Air sampling onto adsorbent tubes combined with thermal desorption
- Thermal extraction of solid samples placed in fritted TDU tubes
- Thermal extraction of liquids placed in µ-vials inside the TDU
- Direct introduction and thermal extraction of liquids such as standards
The TDU supports manual operation and it can be removed in seconds to enable direct liquid sample introduction into the GERSTEL Cooled Injection System (CIS), a PTV-type universal GC inlet.
Up to 196 samples can be analyzed in one automated sequence using one or more methods when the TDU is configured with the GERSTEL MultiPurpose Sampler (MPS).
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. When operating with Agilent MassHunter, just one sequence table operates the complete system.

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 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.
