  • CS6510 Fluoride Ion Sensor

    CS6510 Fluoride Ion Sensor

    The fluoride ion selective electrode is a selective electrode sensitive to the concentration of fluoride ion, the most common one is the lanthanum fluoride electrode.
    Lanthanum fluoride electrode is a sensor made of lanthanum fluoride single crystal doped with europium fluoride with lattice holes as the main material. This crystal film has the characteristics of fluoride ion migration in the lattice holes.
    Therefore, it has very good ion conductivity. Using this crystal membrane, the fluoride ion electrode can be made by separating two fluoride ion solutions. The fluoride ion sensor has a selectivity coefficient of 1.
    And there is almost no choice of other ions in the solution. The only ion with strong interference is OH-, which will react with lanthanum fluoride and affect the determination of fluoride ions. However, it can be adjusted to determine the sample pH <7 to avoid this interference.

  • CS6521 Nitrite electrode

    CS6521 Nitrite electrode

    The nitrite ion-selective electrode (ISE) is a specialized analytical sensor designed for the direct potentiometric measurement of nitrite ion (NO₂⁻) concentration in aqueous solutions. It is a critical tool in environmental monitoring, water treatment, food safety, and agricultural science, where nitrite levels serve as a key indicator of water pollution, process control in wastewater denitrification, and food preservation quality.
    The core of a modern nitrite ISE is typically a polymer membrane or a crystalline solid-state sensor body impregnated with a nitrite-selective ionophore. This proprietary chemical component selectively binds nitrite ions, creating a potential difference across the membrane relative to a stable internal reference electrode. This measured voltage is logarithmically proportional to the activity (and thus concentration) of nitrite ions in the sample according to the Nernst equation.
    A significant advantage of the nitrite ISE is its ability to provide rapid, real-time analysis without the need for complex sample preparation or colorimetric reagents required by traditional methods like the Griess assay. Modern electrodes are designed for both laboratory benchtop use and integration into online, continuous monitoring systems. However, careful calibration across the intended measurement range and awareness of potential interferences from ions like chloride or nitrate (depending on the membrane selectivity) are essential for obtaining accurate results. When used correctly, it offers a robust, cost-effective solution for the dedicated, routine measurement of nitrite.
