 Delsa™Nano Zeta Potential and Submicron Particle Size Analyzer |
The DelsaNano series is a new generation of instruments that use photon correlation spectroscopy (PCS), which determines particle size by measuring the rate of fluctuations in laser light intensity scattered by particles as they diffuse through a fluid, for size analysis measurements and/or electrophoretic light scattering (ELS), which determines electrophoretic movement of charged particles under an applied electric field from the Doppler shift of scattered light, for zeta potential determination.
This series has a broad range of capabilities, including conventional static and automatic titration measurements for both size and zeta potential distributions of suspended particles in a wide range of size and concentration. The DelsaNano also can measure zeta potential of a solid surface or film.
This is the first instrument in the industry that measures zeta potential distribution of concentrated solutions using ELS. It uses the patent-pending forward scattering through transparent electrode technology (FST) to measure zeta potential of particles in various suspension concentrations up to 10 percent or higher depending on particle size. Because of the Brownian broadening of scattering spectrum at high scattering angles, the common practice in measuring concentrated samples using back scattering cannot be used in zeta potential measurement. The FST is the only known technology that can measure zeta potential of particles in concentrated suspensions.
This is the first in the industry that measures zeta potential of solid surfaces or films using ELS. Surface charge or zeta potential of bare, treated,or coated solid surfaces or film such as glass, metal, metal oxide, ceramics, etc. in liquid can be measured using DelsaNano. A unique approach in DelsaNano makes these measurements possible.
