    Frequently Asked Questions (FAQ)

    Q1: What is the difference between zeta potential and isoelectric point?
    A1: Zeta potential measures particle surface charge, indicating colloid stability. IEP is the pH at which the particle’s surface charge is zero, predicting aggregation behavior.
    Q2: Can JS94J-1K20X measure nanoparticles smaller than 0.1 μm?
    A2: The instrument is optimized for 0.1–10 μm particles. For smaller nanoparticles, dynamic light scattering (DLS) instruments are recommended.
    Q3: What types of samples can it measure?
    A3: Primarily aqueous dispersions, including colloids, emulsions, suspensions, and nanoparticle solutions.
    Q4: How accurate is the measurement?
    A4: System error is controlled within 5%, providing highly reliable zeta potential and IEP results.
    Q5: Is it suitable for acidic or alkaline samples?
    A5: Yes, it can operate within pH 2–12, and in some cases 1.6–13, depending on sample stability.
    Q6: Does it require a vibration-free environment?
    A6: For best accuracy, it is recommended to place the instrument on an anti-vibration platform.
