Scattering Methods and Submission of Samples


Small Angel X-Ray Scattering (SAXS)
Structure, size and size distribution of samples such as polymers and particles with a size up to 100 nm can be measured by Small Angle X-Ray Scattering. 
Particle dispersions, polymer solutions or powders with a concentration of at least 1% can be measured. A minimum of 100µl or 100mg of sample is required. Sheets with a size of 10x10x1-2 mm can be measured as well. 
Samples must not be sensitive to light, air or humidity. 


Grazing-Incidence Small Angel X-Ray Scattering (GISAXS)
Nanostructured surfaces or thin films can be measured by Grazing-Incidence Small Angle X-Ray Scattering. A sample fort he demosnstration of this technique will be provided. 


Dynamic Light Scattering (DLS)
The hydrodynamic radius of particles and polymers in a size range between 1 nm up 1 µm can be obtained by Dynamic Light Scattering. 
Samples must not be sensitive to air, light and humidity. A minimum of 500 µl of clear sample is required. 
The sample holder is thermostated and the temperature can be adjusted between 5°C and 90°C. Viscosity of the solvent should be known. 


Static Light Scattering (SLS)
The size and size distributions of various samples such as inorganic particles and polymers in the size range of can hundreds of nm up to several µm can be measured by Static Light Scattering. 
Samples should contain particle dispersions or polymer solutions with a size of hundreds of nanometers up to 10 µm. A minimum of 20 µl of sample with sufficient concentration is required. The sample holder is thermostated and the temperature can be adjusted between 5°C and 90°C.
