Title:
WATER SAMPLING METHOD, WATER SAMPLING DEVICE, AND WATER SAMPLING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/201889
Kind Code:
A1
Abstract:
This water sampling method comprises a detection step for detecting an index value related to the amount of microorganisms in a liquid flowing through a flow path, a determination step for determining whether the index value detected in the detection step has reached a threshold, and a water sampling step for, if a determination is made in the determination step that the index value has reached the threshold, using a water sampling flow path (102a) to sample the liquid flowing through the flow path (102c) as a liquid sample to be used for microorganism measurement.
