  • Overview

    N-REALYZER: Intuitive, Precise, Fast, and Safe Nitrogen and Protein Analysis

    Experience faster, safer nitrogen determination with the N-REALYZER using the Dumas method in a compact, closed system. No hazardous chemicals mean more space and work safety in your lab, allowing flexible use of your fume hood. Enjoy faster analysis times, efficient sample preparation, and significant cost savings compared to Kjeldahl methods. Choose a state-of-the-art, cost-effective, time, and space-saving alternative for nitrogen analysis.

    Intuitive Operation:

    • Self-explanatory user interface for ease of use.
    • Automated process management simplifies everyday laboratory work.
    • Complies with FDA 21 CFR Part 11 and ISO 17025.

    Functional Instrument Design: More Uptime

    • High-quality materials ensure a long service life, plus a 7-year warranty on the combustion furnance.
    • Tool-free operation for easy consumable replacement and fast replacement of process relevant components.

    High Work Safety:

    • Optimized workflows ensure safe daily operations and maintenance steps.

    Wide Range of Samples:

    • Analyze up to 100 samples in series in the patented autosampler which prevents samples from being mixed up.
    • Capable of analyzing both solid and liquid samples, regardless of nitrogen content, thanks to the 2-stage water seperation to completely remove the water content.

    Resource-Efficient Operation:

    • Sample-optimized oxygen addition for resource-efficient operation.
    • Low costs per sample are ensured with the helium-saving function and a specially designed detector to minimize helium consumption and save money.
