    Sample Preparation for PCDD/F, PCB, PCN, PBDE, 209 PCB or CP

    Technical challenges are our life! Thanks to the continuous improvement process, devices and consumables at LCTech are constantly optimised to fulfil the growing requirements.

    LCTech employees are fascinated by uncompromising design that is robust and low maintenance. But almost as important as perfection in the details is the optimum solution for the entire sample preparation process: from extraction to depositing in the analysis vial. As a user, you know that.

    That is why a partnership between manufacturers and customers is so important, particularly for such sensitive analysis of PCDD/F, PCB, PCN, PBDE or CP. The experts at LCTech are aware of this and are only too happy to help you, even if you have difficult questions.

    From the sample to the GC vial:

    Unique extraction system
    with the pressurised fluid extraction (PFE) technique

    The centrepiece of X-TRACTION® is the easy-to-use extraction cell with a magnetic closure (without tools). This is naturally not the only sophisticated feature in this system. Let yourself be impressed by the other advantages.

    The evaporation system for up to 11 extracts at the same time

    The extraction volume (toluene/approx. 90 mL) is controlled by time or sensor and concentrated without supervision to approx. 1 mL within just 1h 50 min (if necessary, to change the solvent). Sample concentration takes place gently and without cross-contamination.

    A unique product family

    DEXTech Pure is the centrepiece of any routine application, DEXTech Heat can be used for all samples, but is recommended for those with hardening fats. DEXTech 16 is the only device that processes 15 samples in one sequence without supervision, day and night. No other provider offers this system diversity, with the same software and transferable methods. Which device best meets your requirements? Take a look at the detailed device overview.

    Very small volumes are D-EVA’s strength

    • For the simultaneous evaporation of up to 53 dioxin fractions to a final volume between
      30 - 150 µL, or
    • For up to 23 PCB fractions to approx. 
      300 - 500 µL

    Reliably controlled via a reference sensor, which carefully prevents evaporation to dryness and thus losses of highly volatile analytes, quickly and without supervision!
