Some are very small, such as nanoparticles with dimensions of 1-100 nm and that might consist of just a few hundred atoms, and some are much larger. In this chapter we consider methods for determining the size of particles.

A column that a manufacturer advertises as using 5 µm particles, however, will contain particles that are smaller and particles that are larger. As the size of the particles has an effect on the pressure it takes to move the mobile phase through the column, knowledge of the distribution of particle sizes is of interest. In this chapter we consider different methods for determining particle size.
