AMERIGO is an innovative analyzer for the characterization of nanoparticle suspensions combining into the same instrument Particle Size and Zeta Potential measurements.

It is based on state of the art version of Dynamic Light Scattering (DLS) and Laser Doppler Electrophoresis (LDE) techniques offering high resolution, accurate and rapid measurement. A flexible system it also allows the use of our unique Vasco Kin In-Situ DLS Remote Head for direct measurement of the sample.

These two techniques provide complementary information about the nanoparticle solution: the size of the nanoparticles and the stability of the formulation.

The WALLIS™ is an innovative high

resolution Zeta potential analyser

purely dedicated to nanoparticle and

colloidal charge characterization.

Based on a modern version of Laser

Doppler Electrophoresis (LDE) technique,

it is the ideal tool for studying colloidal suspension’s stability and nanoparticles’ electrophoretic properties.

Zeta potential range                                      Concentration range 

– 500 mV to 500 mV                                          0.0001% to 10% (w/%)
