NTA PSD of a mixed suspension of 100 nm and 150 nm polystyrene particles (a) and typical SEM picture of the same suspension (b). Cluster analysis of polydisperse polystyrene suspension. Means of the two main clusters are 104 nm and 144 nm. Two false clusters were also detected (c). Simulation of polydisperse polystyrene suspensions with particle diameters of 101 nm and 134 nm (d).
