Abstract: A particle analyzing apparatus (10) includes a processor (42) and storage (41). The processor (42) acquires a volume magnetic susceptibility of an analyte particle (p). The storage (41) stores reference data (43). The reference data (43) indicates a volume magnetic susceptibility of a reference particle of the same type as a type of the analyte particle (p) for each of possible crystal forms of the analyte particle (p). The processor (42) determines a crystal form of the analyte particle (p) on the basis of the volume magnetic susceptibility of the analyte particle (p) and the reference data (43).

Abstract: A magnetic field generation device (100) includes a first magnet (1), a second magnet (2), and a position adjustment mechanism (5). The second magnet (2), together with the first magnet (1), generates a magnetic field. The position adjustment mechanism (5) adjusts a position of the first magnet (1).

Abstract: Volume susceptibilities (?s) of dispersoid particles (s) dispersed in a dispersion medium (m) are first obtained by magnetophoresis. Affinity of the dispersoid particles (s) for the dispersion medium (m) is then analyzed using the volume susceptibilities (?s) of the respective dispersoid particles (s) and a volume susceptibility (?m) of the dispersion medium (m).

Abstract: A particle analyzer (1) includes a measurement cell (2) and a measurement section (10). The particle analyzer (1) further includes a migration section. The migration section includes magnets (3a and 3b), electrodes (4a, 4b, and 4c), a power source (5), and a laser light source (6). The migration section causes migration of particles contained in a medium loaded into the measurement cell (2) by at least two of a magnetophoresis method, a dielectrophoresis method, an electromagnetophoresis method, and a photophoresis method. The measurement section (10) performs determination of a physical quantity of the particles and determination of a migration rate of the particles.

Abstract: A volume susceptibility (?s1) of a first dispersoid particle (s1) is obtained. A second dispersoid particle (s2) that is the first dispersoid particle (s1) to which an adsorbate is adsorbed is obtained. A volume susceptibility (?s2) of the second dispersoid particle (s2) is obtained. An amount of a functional group of the first dispersoid particle (s1) is analyzed through obtaining an amount of the adsorbate included in the second dispersoid particle (s2) based on the volume susceptibilities (?s1) and (?s2) of the first and second dispersoid particles (s1) and (s2).
