Particle characterisation is the process of identifying the particle size, shape, distribution and surface properties. Measurable particle sizes range from below 1 nm to 1 mm, at concentrations ranging from 1 ppm to 70 vol%. A range of analytical techniques are employed including laser diffraction (Mie Theory), dynamic light scattering, nanotracking analysis (NTA) and NMR relaxation.
