The use of air as a fluid for analytical separation of microscopic‐size particles has been given a new impetus by the development of a system involving a dynamic relationship between the powder sample and the air jet. This relationship is such that the powder charge is caused to circulate automatically and at the same time to translate in a direction opposite to that of the incoming air. Particle‐size analysis embodying this principle is described with the samples consisting of ceramic materials. Advantages of the air‐separation method of analysis are discussed.
