Title:
FILTERING COLLECTING DEVICE
Document Type and Number:
Japanese Patent JP2017146168
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To continuously and automatically filter a sea water sample in a short time even in an unstable circumstance where oscillations occur and to obtain a large quantity of filter samples without being affected by the sea water samples collected at other observation points.SOLUTION: A filtering collecting device collects a predetermined sample contained in suspended particles in a sea water sample by filtering the sea water sample at an observation point by a filter. The filtering collecting device includes a cleaning part for cleaning the inside of a line by air-blowing the inside of the line supplied with the sea water sample up to the filter. When the sample is a sample easily affected by contamination by the other sea water sample, the cleaning part performs the co-washing the inside of the line using the sea water sample before performing a filtering step of the sea water sample for collecting the sample after the air-blowing inside the line.SELECTED DRAWING: Figure 7
