Partical Metrix – ZETA-check

Particle interface potentials like the oscillating zeta streaming potential measured in the ZETA-check, represent the level of electrostatic repulsion between particles. The potential is generated by ionic end groups on particles and macro-molecules, respectively. With ZETA-check, the state of the actual charge of dispersions and macromolecular solutions is obtained within seconds. Solutions and dispersions from 0.3 nm up to 100 µm particle size qualify for measurement. The typical concentration is between 0.01 and 40 vol%.
