MAGNETIC SEPARATION METHOD AND AUTOMATED ANALYZER

摘要

A single device carries out a plurality of washing processes for gradually reducing the amount of a magnetic particle solution in a reaction vessel. A first washing process includes a step for inserting a reaction vessel into a recess provided in the magnetic separation device to capture the magnetic substance using a plurality of magnets disposed along the peripheral direction of the recess such that the same pole faces the reaction vessel, a step for solution aspiration, a step for discharging liquid such that the surface of the liquid goes to a position higher than the upper edges of the magnets, and stirring the liquid. A second washing process includes a step for inserting the reaction vessel into the magnetic separation device and aspirating the liquid, discharging the liquid such that the surface of the liquid goes to a position lower than the upper edges of the magnets.
