ABSTRACT
INTRODUCTION It has long been recognized that the scattering of light from small particles could provide information concerning their size and shape. The extraction of this information is mathematically complex, and the development of methods of size analysis based on light scattering has only become practical with the advent of two technologies; these are the use of lasers as light sources, and powerful microcomputers which make the calculations transparent to the user. The application of these techniques has made light scattering one of the most popular particle sizing techniques, and it is replacing many established methods.
