Apparatus for particle size determination in water


Equipment type:  Size and Zeta potential characterization of dispersed particles and molecules in water solution on basis of DLS (DLS: Dynamic Light Scattering)

Manufacturer / Brand: Malvern

Model:  ZEN3600, Zetasizer Nano ZS

Scope of usage:  Particle size characterization of colloid dispersions (Hydrodynamic radius determination), size range from 0,6nm to 6 microns.  Measurement of Zeta potention in water based solution or dispersion on the basis of Electrophoretic mobility (size range for Zeta potential: 5nm to 10 microns).

Examples of application for polymer analysis / information that can be obtained by this method for polymers:  Particle size determination is a characteristic of water-bazed binders or dispersion of nano particles in liquid media. Zeta potential or isoelectric point is an important characteristic for determining stability of colloid systems.

Measurement range: 

Sample limitations: Particle size range from 0,6nm to 6 microns, size range for Zeta potential: 5nm to 10 microns.  Water based samples.

Limitation of application conditions:  20 °C - 70 °C
