Dispersion Characterization Instrumentation Available

PTL has the following dispersion characterisation equipment available:

  • Malvern Zetasizer Nano
  • Nicomp 380/ZLS

Malvern Zetasizer Nano

Features of Malvern Zetasizer Nano

  • Malvern patented NIBS optics allows measurements of samples with little or no dilution
  • Uses a unique disposable zeta potential cell to ensure no cross contamination of samples
  • Can analyze liquid
  • Particle size reported on intensity and volume basis
  • Zeta Potential in aqueous and non-aqueous fluids

Figure 1. Malvern Zetasizer Nano

Malvern Zetasizer Nano is ideal for the following applications

  • Particle Size - measurements of particle size from 0.6nm - 6µm
  • Zeta Potential - measurements

Recommendations for Optimal Output

  • Viscosity of carrier fluid at desired analytical temperature (If not known default values will be used.)
  • Dielectric constant of carrier fluid (applicable for Zeta Potential)
  • Refractive Index and imaginary number (can analyze without)
  • Recommended amount of sample needed: 3-20 mL

Nicomp 380/ZLS

Features of Nicomp 380/ZLS

  • Analytical range: approx 0.010µm - 15µm
  • Can only analyze aqueous suspensions

Figure 2. Nicomp 380/ZLS

Nicomp 380/ZLS is ideal for the following applications

  • Zeta potential (colloidal stability) measurement
  • Quality control

Recommendations for Optimal Output

  • Recommended amount of sample needed: 3mL to 20mL
