Abstract: In a magnetic immunoassay using AC magnetic susceptibility measurement, a signal from non-coupled magnetic particles is prevented to mix with a desired measurement signal from magnetic particles coupled with an object to be measured. A sample vessel in which a mixed solution of an inspection objective sample and the magnetic particles are included is carried by a sample support, such that a precipitation of the magnetic particle coupled with the object to be measured dispersed in the solution by a magnetic field from a dissociating coil is promoted. Next, the sample vessel is carried to the magnetizing coil and the magnetic signal from the non-coupled magnetic particle remaining in a supernatant in the vessel is peculiarly measured by an MR sensor to perform AC magnetic susceptibility measurement with high precision.
