<P>PROBLEM TO BE SOLVED: To provide a magnetophoresis device and a magnetophoresis device for measuring magnetic susceptibility of each particulate and magnetic substance included in each particulate. <P>SOLUTION: Particulates X to be measured are dropped within a tube 10 for drop guidance and let out to the exterior via an opening part 11. Then, a lateral magnetic force F from a magnetic gradient based on magnetic flux from a magnet 20 is caused to act on the particulates X let out of the tube 10, thereby dropping the particulates X to positions B, C, and D displaced from a point A which is a free-fall point. Then, the displacement amount of each point of fall is measured, and prescribed relational expressions are used to measure the volume susceptibility χ of the particulates X, the volume V of the particulates X, or the volume V of the magnetic substance in the particulates X, or the mass of the particulates X. <P>COPYRIGHT: (C)2004,JPO |
