HORIBA Instruments Inc.: The SZ-100 analyzes key particle physical properties including size and zeta potential. It can be used to determine protein and polymer molecular weight and second virial coefficient. Particle size analysis is performed by dynamic light scattering. Zeta potential is measured by electrophoretic light scattering. Molecular weight and A2 are analyzed by static light scattering using a Debye plot. It is capable of performing size measurements at both right angle and backscatter.
