| Abstract: | The paper reviewed principles and classifications of laser scattering, including rayleigh scattering, rayleigh mie gans scattering, fraunhofer diffraction, etc. and laser doppler technology. The application of laser scattering technique on particle size analysis and the advantages & disadvantages of different methods were discussed. The basic parts of the instrument were described and several samples were measured. From the results, it was concluded that the laser scattering granulometric analysis was a quick, precise, non intrusive method. The future developments were also discussed finally. |
