Dumatec™ 8000 Nitrogen analysis in food and feed according to Dumas Tecator™ Line Dumatec™ 8000 gives busy laboratories reliable Dumas results in just three minutes at a low cost per sample. Innovative features reduce start-up time while extending consumable lifetime and software functions allow desktop-operation and traceability. Food and animal feed, liquid, paste and solid samples Dedicated Analytical Solutions

The fast and reliable Dumatec™ 8000 system is approved for product declarations of protein content of food and feed. Approvals encompass organisations such as AOAC, AACC, ISO and ICC. Approved Dumas in as little as three minutes When you need rapid and convenient nitrogen/protein analysis according to Dumas, Dumatec™ 8000 is the answer. No hazardous chemicals are involved and it’s easy to adjust and maintain the instrument during analysis. use of helium is minimized because there is no need for a reference gas flow. Operator time is also low, for example, it is easy and quick to remove the...

Technology Solid or liquid samples are combusted in the presence of catalysts into oxides. The resulting nitrogen oxides are reduced to elemental nitrogen and the water and carbon dioxide byproducts are separated completely. The total resulting nitrogen is registered by the thermal conductivity detector (TCD). The DumatecTM 8000 has a very low detection limit (0.003 mg N). The unit can process up to one gram of a sample, but as for normal food and feed samples, quantities of around 100 - 300 mg give optimum results with minimum consumption. An innovative approach to Dumas Helium is used as...

Before the sample drops from the autosampler into the combustion reactor, the flow is switched from helium (He) to oxygen (O2). The exothermic reaction when the oxygen reacts with the tin capsule containing the sample, raises the temperature in the reactor from 1000 °C up to 1700 - 1800 °C within seconds. At this temperature, and in the presence of specially designed and patented oxidation catalysts, the sample is completely converted into its elemental oxides. The adsorption and desorption operations proceed simultaneously. While one tube is always in-line with the analytical circuit and...

Software for effective operations The DumatecTM 8000 software allows for effective analytical operations and all data is stored for later reporting and traceability. All information can be constantly monitored from the main screen, including a real time graph showing progress with the analysis. A library of methods is pre-installed to support the user with valuable information on the analysis. It’s also possible to create a library of the calibration curves, ready to use for different purposes. An automated leak test can be performed after changing consumables. This ensures that there is no...
