Thermal Desorption Unit TDU for GC & GCMS
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
When configured with the GERSTEL MultiPurpose Sampler (MPS), up to 196 samples can be analyzed in one automated sequence using one or more methods. 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.
