A Method of Measuring and Grading Microscopic Spherical Particles

THE study of particulate matter such as dust often entails either the measurement of the individual diameters of small spherical particles viewed through a microscope, or the determination of the size distribution of such particles by counting the numbers having diameters lying within specified rang...

Description
Summary:THE study of particulate matter such as dust often entails either the measurement of the individual diameters of small spherical particles viewed through a microscope, or the determination of the size distribution of such particles by counting the numbers having diameters lying within specified ranges. The conventional methods of performing these operations have not proved sufficiently accurate for some investigations being undertaken at this Unit, and a new instrument has been devised for the purpose.
