Abstract
The particle-size distribution of 3 commercial sulfur samples was determined by sedimentation and by microprojection (new apparatus described). As far as precision is concerned, there is probably no choice between the methods, but the comparative ease with which results can be obtained by sedimentation should give this method preference for most insecticidal materials.This publication has 1 reference indexed in Scilit:
