ITEX-2 Option
The ITEX-2 Option consists of an add-on module which can be used with any existing or new CombiPAL robot. It performs enrichment of volatile or semi-volatile compounds during headspace analysis. A microtrap filled with adsorbent material, such as Tenax or activated charcoal is placed between the heated CombiPAL Headspace syringe and the syringe needle. No cryofocussing is needed to obtain sharp peaks. The ITEX-2 Option offers faster desorption, a complete deactivated sample path and a shortened syringe. Adding ITEX to your existing COMBI PAL autosampler is now as easy as switching from Liquid to Headspace Sampling.
- 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

Other Accessories for PAL Robots
LEAP strives to find total solutions for analytical lab automation by automating analytical processes for small and large molecules in extracted liquids, solids, and recently in human, animal and plant tissues. We provide the precise robotics and efficient sample prep required by modern measurement techniques such as MALDITOF mass spectroscopy. Our newest specialty customization of CTC Analytics PAL features small workstations that can perform complex liquid handling tasks including HPLC-Purification, SPE, filtration, weighing, heating and stirring. They can be configured as stand alone units or integrated for “just in time” sample prep for LC-MS or GC-MS analysis.
LEAP provides automated workstation instrumentation solutions based on the LEAP CTC PAL X, Y, Z syringe only autosampler robot from LEAP Technologies. This extremely flexible, precise, and adaptable liquid handling robotic platform is available in a variety of lengths and options depending on the requirements of your sample preparation and injections for your UHPLC, LC or GC chromatography.LEAP offers full support and service for the PAL platform in addition to being able to write custom macros, cycles, and scheduling to your applications. Please contact LEAP Technologies on how we can help you get maximized throughput with flexible pipetting automation solutions.
