Title:
Particle size distribution measuring method, particle size distribution measuring device and its control program
Document Type and Number:
Japanese Patent JP6323178
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a particle distribution measurement method, and a particle distribution measurement device and its control program that can easily observe an effect of different member materials in contact with a sample on sample aggregation.SOLUTION: Particle distribution is measured while agitating a sample using plural types of agitating member 21 composed of different materials to compare particle distribution data with each other, which corresponds to respective obtained materials. During this particle distribution measurement, a material of a sample cell 15 is not changed and only the material of the agitating member 21 is changed; therefore, the particle distribution measurement will not be affected, allowing an effect of different member materials in contact with the sample on sample aggregation to be easily observed.
