AUTOMATED ANALYZER

摘要

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.

主权项

1. An automatic analyzer comprising:
a sucking nozzle which sucks reaction solution generated by mixing a sample, magnetic particles, antibody that binds the magnetic particles to a substance in the sample that is to be measured, and labeled antibody including labeled substance; a flow cell having an inlet flow channel, an outlet flow channel and a capture surface and storing a sucked reaction solution therein; and a magnet which captures the substance combined with magnetic particles contained in a reaction solution on the capture surface of the flow cell; wherein the sucking nozzle is directly connected to the inlet flow channel to define a linear flow path from a tip of the sucking nozzle to the inlet flow channel, and wherein both the sucking nozzle and the flow cell are fixed such that they don't move from a time of sucking the reaction solution through a time of capturing the magnetic particles on the capture surface.
