The ITEX-DHS technique uses a gas-tight syringe to collect the headspace and a microtrap inside the syringe needle to efficiently trap and concentrate VOCs through repeated strokes of the syringe. Scalable sensitivity can be achieved based on the number of strokes, making this a versatile approach for samples of both low and high concentrations.
For VOC analysis in many liquid and solid samples, ITEX can be a valuable alternative to classical enrichment techniques offering several benefits in terms of ease of use and robustness.

Easy, simple, robust and automated

• Easy method set-up with few parameters to set
• Simple hardware for an easy access to the trap
• Excellent robustness for long-term operations
• Closed system removing any risk of breakthrough
• Independent trap desorption temperature and flow to maximize desorption process efficiency without impacting GC inlet settings
• SMART gas-tight syringe to enable automatic usage traceability when the ITEX tool is used with the TriPlus RSH SMART autosampler.
• Full control in the Thermo Scientific™ Chromeleon™ CDS to streamline the entire automated workflow
