Features

  • Reliable Dumas with reduced work

    Free your laboratory resources. With Dumatec™ 8000 removal of CO2 is done automatically with the patented self-regenerating adsorption trap within a six position carousel.

  • Disc system Dumatec
    Dumatec's autosampler disc system

    Easy to use auto sampler

    A smart auto sampler disc system gives you batch handling flexibility.

    Up to three discs can be loaded simultaneously allowing up to 117 samples to be analysed unattended.

  • Three stage water filtering system
    Three stage water filtering system

    Three-stage water filtering system

    The unique three-stage water removal system increases the lifetime of the water trap-packing many times.

    The by-product water (H2O) is separated from the gas mixture by three water traps – F1, F2 and F3. F1 is a water condensation tube. F2 is a Perma Pure gas membrane. F3 is a silica gel water trap.

Dumatec™ 8000 - Automated Dumas Analysis

How to manage reference test data for NIR calibration faster and more cost effectively. This video animation shows how a Dumas (nitrogen) analysis instrument can be connected to a network so that data can be accessed and managed from anywhere. Not only, does it save time, it also cuts the risk of human error by avoiding manual data entry.
