A system for measuring a particle size distribution of particles of a particulate matter

摘要

It is an objective of the present invention to provide a system for measuring the particle size distribution of the particles of a particulate matter and, simultaneously, its crystalline nature.;This objective is achieved according to the present invention by a system for measuring the particle size distribution of the particles of a particulate matter; comprising:a) a particle separation unit (4), such as a decanter unit, a centrifugal unit or a magnetic/electric field unit, being designed to force the particles (10a, 10b) to move through a moderating agent (8), such as liquid or a suspension;b) a radiation source (12) and a respective detector (14) enabled to measure dynamically the transmitted and/or particle absorbed amount of the incident light in at least a section of said particle acceleration unit (4), said measurement being preferably performable during predetermined time intervals;c) a radiation source (12) and a respective detector (14) enabled to simultaneously measure dynamically the beam - particle interaction, such as diffraction pattern, of the particles (10a, 10b) moving along at least a section of said particle acceleration unit (4), said measurement being preferably performable during predetermined time intervals.;The present system therefore allows to measure both the particle size distribution as well as the crystalline nature of the powders at the same time thereby achieving a higher resolution within a shorter investigation period as compared to the methods known so far.
