The NanoPlus utilizes photon correlation spectroscopy and electrophoretic light scattering techniques to determine particle size and zeta potential. Compact and easy to use with an extended analysis range, intuitive software, and multiple sample cells to fit the user’s application, the instrument can measure particle size in the range of 0.6 nm to 10 μm with sample suspension concentrations from 0.00001% to 40% and zeta potential of sample suspensions in the -200 mV to +200 mV range with concentrations from 0.001% to 40%. The NanoPlus is available in three model configurations.
