Tags: , ,

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