Document Type and Number:
WIPO Patent Application WO/2022/234751
Kind Code:
A1
Abstract:
This analysis method for a membrane-occluding substance includes: projecting visible light onto a monitoring-use separation membrane through which test water has been passed; measuring, using a visible light spectrophotometer, the reflection intensity of the visible light reflected by the monitoring-use separation membrane; and identifying the occluding substance in the membrane on the basis of the reflection intensity of the visible light which was measured.
