• 67.69 % by volume of sample was seen to be < 10.00 µm.
Due to the' sample being a dye, and containing small particles, the liquid module was used.
Several solvents were tried, in order to determine a suitable medium that provided maximum dispersability, but with minimum solubility. Acetone was finally selected as the most suitable dispersant.
