AMERIGO - Nanoparticle and Zeta Potential Analyzer

The AMERIGO is a three-in-one equipment engineered to carry out high-resolution nanoparticle size and zeta potential measurements, with the exclusive ability to plug an external remote probe for in situ and contactless measurements. AMERIGO integrates all the technologies and innovations created and patented by Cordouan Technologies.

AMERIGO combines the performances and progressive functionalities of the WALLIS zeta potential analyzer and the VASCO Kin particle size analyzer. This enables the same instrument to be used for high-resolution zeta potential measurements and high-resolution real-time particle size kinetic measurements.

Furthermore, the external in situ remote probe option enables users to “bring the measurement” directly to the sample to carry out contactless measurement without sampling.
