        CombiPAL ITEX


Rapid and efficient sample enrichment of volatile and semi-volatile compounds in solid, liquid and gaseous samples

In-tube extraction and direct thermal desorption using proven industry standard adsorbents (Tenax TA, Carbotrap, Carbosieve etc.)

Syringe only concept for transparent sample handling, no sample loops, transfer lines, or switching valves

Top mounted on GC's, saves valuable bench space

No GC injector modifications, no cryo-focussing necessary

Interfaces with any CombiPAL System, controlled by all major GC/GC-MS

Steps of CombiPAL ITEX Cycle

- Sample is heated and / or agitated in a sealed sample vial until equilibrium is achieved
- The Trap needle pierces the vial septa and the syringe pumps the headspace through the Trap
- The loaded ITEX Trap is flash heated up to 350°C and desorbed into the hot GC Injector
- After thermal desorption the hot ITEX Trap is cleaned with inert flush gas
