Particle size analysis — Small angle X-ray scattering (SAXS)
Preview
Summary
This document specifies a method for the application of small-angle X-ray scattering (SAXS) to the
estimation of mean particle sizes in the 1 nm to 100 nm size range. It is applicable in dilute dispersions
where the interaction and scattering effects between the particles are negligible. This document
describes several data evaluation methods: the Guinier approximation, model-based data fitting, Monte-
Carlo–based data fitting, the indirect Fourier transform method and the expectation maximization
method. The most appropriate evaluation method is intended to be selected by the analyst and stated
clearly in the report. While the Guinier approximation only provides an estimate for the mean particle
diameter, the other methods also give insight in the particle size distribution.
