Title:
METHOD FOR DETERMINING AGGREGATION STATE AND METHOD FOR PERFORMING AGGREGATION PROCESS
Document Type and Number:
WIPO Patent Application WO/2024/018884
Kind Code:
A1
Abstract:
This method for determining an aggregation state includes irradiating a particle-containing liquid with laser light and then determining the aggregation state of the particles on the basis of the reception intensity of scattered light that is derived when the laser light is scattered by the particles, the method having: a calculation step for creating a correlating equation between the total reception intensity S calculated from the reception intensity and an actual measured value of a fluctuation index representing fluctuation in the reception intensity and then calculating a compensation coefficient C that is based on the correlating equation; and a determination step for determining the aggregation state of the particles by using a compensation value that is derived by compensating the actual measured value of the fluctuation index with the compensation coefficient.
