Cordouan Product Offering: AMERIGO

AMERIGO / AMERIGO Plus

The AMERIGO is a powerful, all-in-one system that combines DLS particle size analysis with LDE-based zeta potential measurement. Designed for versatility and ease of use, it delivers high-resolution, time-resolved data across a wide particle size range.
  • Dual Measurement System: Perform both nanoparticle size measurement and zeta potential analysis using a single instrument
  • Real-Time, Time-Resolved Data: Monitor particle size and surface charge during reactions, formulation processes, or over time
  • Contactless DLS Measurement: Remote optical heads allow in situ testing - no need for sample extraction or batch preparation
  • Durable, Universal Electrodes: Reusable dip cell electrodes are compatible with aqueous and non-aqueous solvents across a wide pH range
  • Streamlined Workflow: Use a single cuvette for both measurements- no additional consumables, transfers, or tools required
  • Advanced Software (AmeriQ™): Offers programmable experiments (e.g., zeta potential vs. pH), dynamic slicing, and SOP support
  • Measurement Ranges:
    • Particle size: 1 nm - 100 µm
    • Zeta potential: High resolution down to ±0.1 mV
    • Molecular weight : 0.9 kDa - 20 MDa ±5%

Advantages of Nanoparticle Size & Zeta Potential Analyzers

  • Comprehensive Particle Characterization: Understand both particle size distribution of nanoparticles and their electrostatic stability
  • Improved Product Performance: Ensure stable formulations by analyzing interactions between particle size and surface charge
  • Real-Time Decision Making: Gain immediate feedback on dispersion behavior, agglomeration, and formulation changes
  • Versatile Sample Handling: Analyze samples in water, solvents, acids, or bases using robust, reusable electrode cells
  • High Accuracy & Repeatability: Built for critical applications in formulation R&D, QA/QC, and academic research
