Title:
ANALYZING DEVICE AND ANALYSIS METHOD
Document Type and Number:
WIPO Patent Application WO/2019/039601
Kind Code:
A1
Abstract:
An analyzing device (10) is provided with a magnetic field generating unit (20), an observation unit (30), a processing unit (42) and a storage unit (41). The magnetic field generating unit (20) generates a magnetic field to cause magnetophoresis of a particulate organism (p) being analyzed. The observation unit (30) observes the particulate organism (p). The processing unit (42) measures the magnetophoretic velocity and the particle size of the particulate organism (p) from observation results obtained by the observation unit (30), and measures the bulk susceptibility of the particulate organism (p) on the basis of the measured magnetophoretic velocity and particle size. The storage unit (41) stores reference data (43) indicating a relationship between the bulk susceptibility and the particle size of a reference particulate organism. Further, the processing unit (42) analyzes the particulate organism (p) by comparing the bulk susceptibility and the particle size of the particulate organism (p) with the reference data (43).
