    Evaluation of Dispersion Stability by Zeta Potential/Particle Size

    As the absolute value of zeta potential increases, colloidal systems give generally stable dispersions due to electrostatic repulsion between particles. However, as the zeta potential approaches zero, the stability of the dispersion reduces and aggregation becomes likely.

NanoPlus HD Zeta Potential Measurement

The NanoPlus HD is designed to measure electrophoretic mobility at several points in the cell to obtain a position (i.e. stationary point) not influenced by electroosmotic flow. As a result, the instrument can calculate and accurately measure electrophoretic mobility, even if the electroosmotic profile of the system is asymmetrical due to adsorption or sedimentation of the sample on the cell walls. The Multi-point determination allows for exceptional repeatability and reproducibility.

Design utilizes a straight capillary with parallel electrodes to provide greater accuracy by eliminating error associated with variable migration direction seen with other types of cell geometry.

  • null

  • null

    Wide sample application. Soft sample-like fibers can be measured

FST Method for Concentrated Samples

By conventional methods, scattered light from a concentrated suspension can not be measured correctly due to multiple scattering (A) or in very concentrated solutions due to its ability to transmit light. The FST method detects the scattered light from particles through a transparent electrode.

The optical path length is minimized to reduce the effects of multiple scattering. Thus, the NanoPlus HD can perform a zeta potential measurement of a concentrated suspension with a high degree of accuracy (B).
