FOREIGN TECHNOLOGY DIV WRIGHT-PATTERSON AFB OHIO
Pagination or Media Count:
A method is described for determining the particle size distribution 1 - 40 micrometers of small powdered samples 5 - 30 mg. The measurement is carried out with a photosedimentograph consisting of a Leitz-sedimentometer, a light source of constant intensity, a commercial recorder, a thermostat, and some other accessories. The analysis is semi-automatic, and leads to accurate results within only one hour.
