Abstract
Stepped portions of a flow channel are reduced by completely fixing the channel that extends to the measuring unit, and reducing connections in the channel, thereby to suppress a disturbance in the flow of the liquid suctioned into the measuring unit. A means is provided so that the reaction solution and reagent suctioned will move towards the channel through which the liquids are suctioned.
Claims9
An automated analyzer comprising:
- a nozzle for suctioning a reaction solution generated by mixing a sample, magnetic particles, an antibody that binds the magnetic particles to a substance in the sample that is to be measured, and a labeled antibody including a labeled substance;
- magnetic separation means for capturing magnetic constituents contained in a reaction solution suctioned by the nozzle, in such a manner that only the magnetic constituents are captured to separate magnetic constituents and nonmagnetic constituents from each other;
- and
- a measuring unit for quantitatively determining the magnetic constituents captured by the magnetic separation means, the magnetic constituents being bound to the substance to be measured;
- wherein the nozzle is directly connected to the measuring unit.
