DelsaNano C Submicron Particle Size Analyzer with Autotitrator

Area Linked to: 
Mineral Processing
Research Area: 
Surface Chemistry

The DelsaNano C 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 instrument has an advantage of determining iso-electric-point (iep) of minerals suspension by using an autotitrator whwerin the zeta potential is plotted against pH of the medium of the suspension.
