Small Angle X-Ray Scattering Method

can be used in a size range of about 1 to 300nm. Its advantage is , that the scattering mainly results from the differences of the electron density between the particles and their surrounding. As internal crystallites of external agglomerates are not visible, the measured size always represents the size of the primary particles and the requirement for dispersion is strongly reduced [Z.

Inst. 3, No. 1, (1996); ISO/TS 13762:2001 Particle size analysis – Small angle X-ray scattering method].
