This instrument utilizes Electrokinetic Sonic Amplitude (ESA) technology for real-time zeta potential analysis. It is capable of analyzing dispersions across a wide concentration range, from 0.01 weight % to 99.0 volume %, and can handle various sample types including emulsions, pastes, and semisolids with particle sizes ranging from less than 1 nm to 100 µm. A key advantage is its ability to perform measurements while stirring, titrating, or adding constituents, making it ideal for concentrated, colored, turbid, viscous, or crème-like samples that are challenging for other methods. The system also simultaneously measures conductivity, temperature, and pH, and supports automated procedures for determining the isoelectric point (IEP) and optimizing additive concentrations.
