Comparison of Flour Particle Size Distributions Measured by Electrical Resistivity and Microscopy.

A comparison was made of procedures for particle size distribution analysis on a group of air-classified flour samples. The procedures were microscopic (with the use of Martin's diameter) and electrical resistivity (with the Coulter counter). Shape correction factors derived by two independent means, using methods of moments, were in good agreement. It appears that the microscopic method is oversizing and a correction factor should be applied to the microscopic data. When this is done, particle size distribution data obtained by the two methods appear to be very similar.
