particle size for individual populations (Fig.

). For particles of similar compo-
sition, particle scattering intensity increases with particle size.
For mixtures of particles of different composition the ability to plot, for each
particle, scattered intensity against particle diameter allows information to be
gained about the composition of the mixture.
As example, Fig.

illustrates the size/concentration distribution of particle
for a sample, followed by the analysis report generated by the LM10 software. The
distribution diagram indicates
that
there were four
significant groups of
nanoparticles in the sample.
