Malvern Zetasizer Nano
Features of Malvern Zetasizer Nano
- Technology 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 and powder suspensions
- 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 3nm - 10µm
Recommendations for optimal output
- Viscosity of carrier fluid at desired analytical temperature
- Dielectric constant of carrier fluid (applicable for Zeta Potential)
- Refractive Index and imaginary number if available
- Recommended amount of sample needed: 100 mg (dry sample) 20 mL (wet sample)
Microtrac UPA 150
Features of Microtrac UPA 150
- Analytical range: approx 3nm - 6µm
