Supplies - GERSTEL Thermal Desorption System TDS and Pyrolysis Module PM 1 and Tube Conditioner TC 1 / 2 and Thermal Extractor TE 1 / 2

Significance of the Topic

The GERSTEL Thermal Desorption System (TDS) and its associated modules address the critical need for reliable, high-sensitivity analysis of volatile and semi-volatile organic compounds (VOCs/SVOCs) across diverse fields such as automotive materials, pharmaceuticals, food flavor, environmental monitoring, and forensics. By enabling solvent-free sample introduction, clean baselines, and low detection limits, TDS ensures compliance with standardized methods and enhances data quality in research and quality control.

Objectives and Overview of the System

This summary provides an expert overview of the GERSTEL TDS family, including:

• Thermal Desorption System TDS
• Pyrolysis Module PM 1
• Tube Conditioner TC 1/2
• Thermal Extractor TE 1/2

It also highlights the comprehensive range of certified consumables and spare parts designed to maintain peak performance and instrument longevity.

Methodology and Instrumentation Used

GERSTEL’s approach combines controlled thermal desorption, pyrolysis, tube conditioning, and extraction under an inert gas flow. Key features include:

• Valve-free flow paths to eliminate cold spots and active sites
• Automated sequences managed by MAESTRO software integrated with Agilent ChemStation or MassHunter
• Support for up to five GERSTEL Twister® stir-bars per run
• Multi-desorption capability for enhanced sensitivity

Instrumentation

• TDS (Thermal Desorption System) standard unit
• PM 1 (Pyrolysis Module) for thermal decomposition studies
• TC 1/2 (Tube Conditioner) for bulk conditioning of tubes and stir-bars
• TE 1/2 (Thermal Extractor) for direct extraction of solids or liquids onto sorbent tubes
• MAESTRO control software
• Compatibility with all standard GC/MS platforms and CIS inlets

Main Results and Discussion

GERSTEL’s systems demonstrate:

• Excellent recovery of active and high-boiling analytes due to inert, valve-free design
• Versatility through a wide selection of single- and multi-bed sorbent tubes (e.g., Tenax, Carbotrap, Carbopack, Carboxen, Carbosieve)
• Traceable tube identification via unique serial numbers and storage containers with PTFE seals
• Dedicated tube adapters, O-ring kits, ferrules, and transfer line options (ProSteel®, Silcosteel®, Sulfinert®)

Benefits and Practical Applications

The GERSTEL TDS portfolio offers laboratories:

• Modular expansion to meet evolving analytical challenges
• Low detection limits for regulatory compliance
• Robust, maintenance-friendly consumables to minimize downtime
• Flexibility in sorbent choice to target a broad molecular range (C1–C30)

Future Trends and Potential Applications

Emerging directions include:

• Integration of advanced sorbent materials for ultra-trace analysis
• Enhanced automation and remote monitoring capabilities
• Expansion into non-targeted screening with high-resolution MS
• Broader use in environmental and biological sample matrices

Conclusion

GERSTEL’s Thermal Desorption System and its accessory modules represent a comprehensive solution for high-performance VOC/SVOC analysis.
