PURPOSE:To separate relatively large particles with high resolving power by disposing a magnet to the side face of a centrifugal sepn. column and using magnetic fluid as a developing liquid. CONSTITUTION:This invention relates to a continuous fluid separator for making a sepn. and analysis by using a centrifugal force field and magnetic field gradient as an acting field to generate an ultralayer of diamagnetic particles and paramagnetic particles, in which a spacer 3 having a blanked groove of a channel is sandwiched by the inside peripheral surface of a column base 1 and the outside peripheral surface of an inside ring 2 and is retained by a stopper ring 5 to provide the channel and the cylindrical rear earth permanent magnet 4 divided to a plurality is disposed to the inside of the ring 2. The magnetic fluid is used as the developing liquid. Then a concn. gradient is generated in the channel and a sample zone is formed at approximately the same point as the solvent density determined by the concn. The magnetic field acts on the particles of different diameters in proportion to the cube of the particle size and the particles are thus separated. |
