The sizing accuracy of a commercially available laser optical liquid‐borne particle counter is investigated. A calibration study, using aqueous suspensions of non‐absorbing, monodisperse, spherical polymer particles, and a study using suspensions of non‐spherical polydisperse, alumina particles are conducted. The experimental results from the spherical polymer study show an excellent agreement with the theoretical Mie light scattering calculations. The accuracy of the spherical polymer sizing is shown to be within 20% of the actual size. The alumina particle readings are compared to the readings of four different particle sizing instruments and to scanning electron microscope pictures. Although quantitative comparisons are difficult to make between the instruments, the results show a good agreement for the batch of particles with a narrower size distribution.
