CAPTURING DEVICE AND MEASURING DEVICE FOR SUSPENDED PARTICULATE MATTER IN ATMOSPHERE

摘要

PROBLEM TO BE SOLVED: To provide a capturing device capable of continuously capturing a suspended particulate matter in the atmosphere in a largely labor saving state or an unmanned state, and further provide a measuring device using it.;SOLUTION: The atmosphere is sucked into a collecting vessel 1, a discharge electrode 4 for charging suspended particulate matter P and a dust collecting electrode 6 for collecting the charged suspended particulate matter P using potential difference are arranged in the collecting vessel 1. The dust collecting electrode 6 is formed in a flexible film shape, penetrated through the collecting vessel 1, and arranged movably from the outside. By moving the dust collecting electrode 6 by winding or the like, the dust collecting electrode 6 after trapping of the charged floating particulate matter P can be substantially replaced by a new one. A measuring section is constituted so that the dust collecting electrode 6 pulled out of the vessel after the trapping of the charged floating particulate matter P is used as a specimen holding member, thereby forming the device for continuously measuring the physical properties or the like of the charged suspended particulate matter P.;COPYRIGHT: (C)2004,JPO
