    Opći opis

    HPLC is a technique in analytical chemistry used to separate, identify, and quantify each component in a mixture. It relies on pumps to pass a pressurized liquid solvent containing the sample mixture through a column filled with a solid adsorbent material. Each component in the sample interacts slightly differently with the adsorbent material, causing different flow rates for the different components and leading to the separation of the components as they flow out the column.

    Princip rada i mjerna tehnika

    Gradient pumps offer selectable one-, two-, or four-stroke proportioning is available to optimize gradient precision on long, shallow gradients while minimizing gradient delay volume on steep, fast gradients.
    Reliable results -- Intelligent design, including electronic flow and in-line, high-speed proportioning valves, assures accurate and reproducible results.
    GLP compliance -- Run-and-error logs maintain a complete audit trail of operating parameters, set points, errors, and faults.
    Built-in automations -- Up to five methods can be built and stored at the pump. Choose the appropriate method with a single keystroke.
