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
  • Can analyze liquid and powder suspensions (organic or inorganic solvents) in most carrier fluids
  • Reports data on a Volume and Intensity basis

Figure 2. Microtrac UPA 150

Microtrac UPA 150 is ideal for the following applications

  • Quality control

Recommendations for optimal output

  • Viscosity of the carrier fluid at two temperatures (PTL has viscosity information on many common carrier fluids, for further information please call)
  • Refractive index (recommended)
  • Recommended amount of sample needed: 1 to 5 grams (dry sample) 10 to 50mL (wet sample)

Nicomp 380/ZLS

Features of Nicomp 380/ZLS

  • Analytical range: approx 3nm - 1µm
  • Classic technology within dye/pigment, emulsion, and protein industries
  • Reports data on a Volume, and Intensity basis
  • Zeta Potential determination

Figure 3. Nicomp 380/ZLS

Nicomp 380/ZLS is ideal for the following applications
