The SZ-100 nanopartica series instruments are flexible analytical equipments for characterizing the physical properties of small particles. Depending on the configuration and application, the system can be used as a particle size analyzer, or also used to measure zeta potential, molecular weight, (MW) and second virial coefficient (A2). Typical applications for the SZ-100 include nanoparticles, colloids, emulsions, and submicron suspensions.

Particle size analysis is performed by dynamic light scattering (DLS). Depending on the physical properties of the sample, the dynamic range is 0.3 nm – 8 µm. The lower limit is influenced by concentration, how strongly the sample scatters light and the presence of large unwanted particles; while the upper limit is influenced by the density of the sample.

• Particle size, zeta potential, molecular weight, and second virial coefficient all in one instrument

• Wide range of particle sizes and concentrations

• Particles size measurements at both 90° and 173°

• Multiple particle size measurement modes for working with small particles and weak scatterers

• Small volume cells for both particle size and zeta potential

• Optional pH controller for automatic titration of zeta potential vs.pH
