Product catalog summary
Overview of the Thermal Desorption Unit (TDU):
The GERSTEL Thermal Desorption Unit (TDU) is an advanced, flexible system designed for thermal desorption and extraction of gases, liquids, and solids. It integrates seamlessly with modern gas chromatography (GC) systems without requiring additional bench space. The TDU is engineered to minimize analyte loss and memory effects, offering high productivity and throughput.
Key Features:
  • Design: The TDU employs a "Liner-in-Liner" concept, eliminating the need for valves or transfer lines, thus reducing active sites and ensuring efficient analyte transfer.
  • Modes of Operation: It supports both split and true splitless modes, accommodating a wide range of concentrations and protecting the GC column from contamination.
  • Automation: The system can be automated with the GERSTEL MultiPurpose Sampler (MPS), allowing for the analysis of up to 490 samples in one sequence.
  • Sample Types: Capable of analyzing GERSTEL Twisters®, adsorbent packed tubes, solids, and liquids.
GERSTEL Twisters®:
The Twister is a patented tool for Stir Bar Sorptive Extraction (SBSE), enabling ultra-trace determination of organic compounds. It is highly sensitive, up to 1000 times more than Solid Phase Micro-Extraction (SPME), and can be used for air monitoring.
Advanced Features:
  • ATEX Option: Allows for solvent venting, thermal extraction of solids, and the addition of liquid standards.
  • Universal Sample Introduction: Supports a wide range of applications with temperature-programmed desorption and flexible refocusing options.
  • Productivity: Automated desorption of multiple samples without reconfiguration, ensuring high throughput.
  • Sealed Sample Storage: Ensures sample integrity and reliable results by preventing analyte loss and contamination.
MAESTRO Software:
The MAESTRO software provides efficient control of the TDU system, allowing for easy operation and integration with chromatography software. It supports automated sample preparation and introduction, enhancing system utilization and throughput.
Applications:
  • Dynamic Headspace (DHS): Automates the extraction of VOCs from samples, improving performance for various sample types.
  • Thermal Extraction in Micro-Vials (ATEX): Prevents contamination of the GC/MS system by using disposable micro-vials for volatile extraction.
