The SZ-100 nanopartica series instruments are flexible analytical tools 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.
Features:
- 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.
- Extremely low sample volume makes it possible to measure precious or rare samples.
- Modern signal processing electronics efficiently convert optical signals to mobility and zeta potential information. There is no need to manually calculate particle velocity or match speeds.
