| titleOfInvention | Detection of magnetic fine particle in liquid and device |
| abstract | PURPOSE: To rapidly and efficiently perform detection of a foreign matter and measurement thereof by attracting the foreign matter to magnetic fine particles by gradient of a magnetic field impressed on the downstream side of a laminar flow and changing the proceeding direc tion of these magnetic fine particles to separate them and measuring the number of the separated magnetic fine particles. n CONSTITUTION: When magnetic gradient is imparted from the outside of a capillary 4 with one set of magnets 6, 7, magnetic fine particles 1a with a foreign matter attracted thereto and magnetic fine particles 1b free from attraction of the foreign matter receive force propor tional to the magnetic moment incorporated in the magnetic fine particles 1a, 1b. The direction of force due to the magnetic gradient is regulated to the direction orthogonal to the direction of a laminar flow 3 and therefore acceleration is imparted to this direction. As a result, the processing directions of the magnetic fine particles 1a, 1b are curved. At this time, the particles 1a with the foreign matter attracted thereto are large in mass and therefore accelera tion is made small. The particles 1b free from attraction of the foreign matter are small in mass and therefore acceleration is made great. Accordingly, in the bending amount of the particles 1a, 1b in the direction orthogonal to the direction of laminar flow after lapse of a constant time, the bending amount of the particles 1a is made smaller than the bending amount of the particles 1b. Therein when a partition plate 8 is provided in the laminar flow 3, the particles 1a are separated from the particles 1b. n COPYRIGHT: (C)1991,JPO&Japio |
