Abstract: Advances in computer technology have led to progressive development of optical methods. Optical methods can be divided into two groups: direct and indirect methods. The first group includes those methods that directly analyse photographic or electronic image record. The indirect methods use the relationship between particle size and properties of the scattered light. Laser diffraction uses scattering of electromagnetic waves on the particles to measure the particle size distribution. Angle of scattered light is inversely proportional to size of particle at which the incident light beam is scattered. This study presents the basic principles of laser diffraction, particle size analysis theories and design of a laser particle sizer ANALYSETTE 22 MicroTec plus (FRITSCH). Further, the advantages and disadvantages of this method are present in comparison with pipette method.
Keywords: particle size analysis, optical methods, laser diffraction, analysette 22 microtec plus
