AMERIGO – Particle Size and Zeta Potential Analyser

AMERIGO is an innovative analyser for the characterisation 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.

Key Features and Benefits

  • Three-in-one instrument
  • Possibility to perform the measurements in a standard cell…
  • …or using an interchangeable remote heads (see below)
  • Sample compartment designed for standard 10mm x 10mm cuvettes – no specific consumables
  • Measurements in two configurations: backscattering (170°) or transmission (17°)
  • High durability vitreous carbon electrodes
  • Easy-to-use intuitive software
  • Software correlator – dynamic time slicing and data analysis feature
  • Small footprint
