Center Smart Materials and Adaptive Systems CeSMA
Exemplary particle distributions (volume & number) depending on the particle size
Exemplary measurement of Zeta Potential and conductivity depending on pH-value
With many years of experience in particle analytics, CeSMA offers the following particle size and shape analysis methods:
- Particle size analysis
- Particle diameter 10 nm to 2 mm by laser diffraction
- Particle diameter 5 nm to 10 µm by ultrasonic absorption and/or electroacoustic measurement in concentrated samples
- Particle diameter 0.3 nm to 10 µm by dynamic light scattering
- Particle shape analysis by dynamic image analysis: particle diameter 5 μm to 1 mm
- ZETA – Potential analysis by electroacoustic measurement and Laser Doppler Micro-electrophoresis: ZETA potential and conductivity of dispersion of charged particles depending on the pH value
The following measuring devices are used for this:
- Microtrac MRB: Type Bluewave + Type SIA
- Colloidal Dynamics: Type Acoustosizer IIs
- Malvern: Type Zetasizer Nano ZS
