Laser-Based Three Wavelength Extinction Analysis of Suspended Latex and Oxide Particles

The three wavelength extinction method (3-WEM) was applied for the on-line particle analysis of suspensions of monodisperse latex beads and polydisperse metal oxide particles of industrial interest. Comparative measurements were performed by photon correlation spectroscopy (PCS). The data of latex particles obtained by 3-WEM and PCS are in good agreement with the manufacture’s values. Also, the values of oxide particles measured by means of the two techniques are in reasonable agreement despite of the irregular particle shape. Discrepancies are observed by comparing the oxide particle size results with those of scanning electron microscopy, which is due to the broad sample distributions and shape irregularities.
