Physicochemical methods

 

We use various physicochemical methods to characterize our nanomaterials and powders. In our laboratories we use light scattering (DLS) and thermogravimetric analysis (DTA/TGA). In addition, we use many other methods in cooperation with the chemistry department, e.g. ICP-OES, FT-IR, UV-vis, TEM, CHN analysis and BET.

 

Dynamical light scattering

Litesizer Copyright: © IfK
Manufacturer Anton Paar
Type Litesizer TM 500 with dosing system
Technical features Measuring ranges:
- Particle size: diameter 0,3 nm–10 µm
- Zeta potential> +/- 600mV, 3,8 nm–100 µm
- Molecular mass: 980 Da–20.000 kDa
Application Characterization of particles in dispersions and suspensions using light scattering technology. Measurement of particle size, zeta potential, electrophoretic mobility, molecular mass and transmission. The dosing system enables the fully automated dosing of additives and simultaneous measurement of the sample, e. g. the particle size depending on the pH.
