Particle Characterization

Diverse, Complimentary Techniques

by Angelo DePalma, PhD

Particle sizing methodologies range from straightforward sieving and sedimentation analysis to advanced laser-based light scattering techniques, microscopy/imaging, nanoparticle tracking analysis, and others.

Zeta Potential Determination for Macroscopic Solid Samples

by Anton Paar

The majority of the zetameters are based on the electrophoresis measuring principle where the zeta potential for a colloidal system is analyzed by measurement of the electrophoretic mobility of the particles.
