    D200 Dumas Nitrogen Analyzer
     
    Introduction:
    The Dumas Nitrogen Analyzer detects the nitrogen/protein content in the sample through the steps of combustion, purification, reduction, and thermal conductivity detection. No sample pre-treatment is required, and the analysis time for a single sample is only 4 minutes, which is fast and efficient; the reaction process neither uses nor produces toxic and harmful substances, which is safe and environmentally friendly. It is widely used in the determination of total nitrogen in vehicle urea, grain (grain), seeds, meat, meat products, animal feed, dairy products, red wine, fertilizer and soil.
    Features:
    1. Using a single-disk 120-position autosampler to realize direct analysis of large sample quantities
    2. Equipped with a fast cooling function, it only takes 30 minutes to cool down to the shutdown temperature
    3. The core components adopt the original Japanese SMC® gas circuit and the Dutch Bronkhorst® mass flow controller to improve the long-term reliability of the instrument
    4. Adopt new consumables and high-efficiency metal condenser water removal technology to improve the service life of consumables
    5. Secondary combustion and oxidation: in the primary combustion tube with pure oxygen for combustion, the sample completes preliminary oxidation and digestion, and the difficult-to-oxidize part is carried by the carrier gas through the secondary combustion tube, and is further oxidized by the mixture of Pt catalyst and copper oxide to ensure complete digestion
    6. Three-stage water removal: first remove most of the water through an electronic condenser to reduce the pressure of the chemical water removal agent, and then remove trace amounts of water through the primary drying tube and the secondary drying tube;
    7. High-efficiency reduction: High-efficiency reducing agent reduces nitrogen oxides to nitrogen while absorbing excess oxygen;
    8. TCD detection: The nitrogen generated by the reduction is detected by the thermal conductivity detector (TCD).
