The Zetasizer Nano Z measures the zeta potential of dispersed particles and macromolecules in solution over a size range 3 nm to 10 microns. The set-up is operating with a 4 mW, 633 nm He-Ne laser and the scattered light is detected at an angle of 17°. The temperature range can be tuned between 2 °C and 90 °C. The zeta potential is measured using a combination of measurement techniques: electrophoresis and Laser Doppler Velocimetry.
