Paper Abstract

There has been in recent years an ever increasing need for a fast determination of particle size distribution in systems where the distribution changes with time so much that the conventional methods are not applicable unless one sacrifices significantly precision of the result obtained. In our laboratory the possibility was explored of obtaining distribution curves by determining exclusively the angular location of scattering extrema, i.e. maxima and minima. Several possible methods of procedure were found to be promising. One of these is being described in the following. On using a minicomputer in which one stores that part of the information available from Tables just issued, which is applicable to a given system, the size distribution should be obtainable within less than five minutes including the time needed for angular location of extrema.
