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 automated analyzer comprising:
a first nozzle which sucks a reaction solution in a reaction vessel and one or more reagents in a plurality of reagent vessels, and whose location is fixed during analysis; a flow cell which is connected with the first nozzle and into which the reaction solution is sucked by the first nozzle;
a detector which quantitatively detects a substance to be measured in the reaction solution sucked into the flow cell; a retainer having a plurality of mounting regions on which the reaction vessel that accommodates the reaction solution and the reagent vessels that accommodate the reagents necessary for the analysis are placed, respectively; a horizontal transport mechanism which rotationally or linearly moves the retainer in a horizontal plane to transport one of the mounting regions on which the reaction vessel or one of the reagent vessels is placed in accordance with a phase of the analysis to a first position below the first nozzle; a vertical transport mechanism coupled to the retainer and which moves the retainer in a vertical direction to transport the one of the mounting regions on which the reaction vessel or one of the reagent vessels is placed from the first position to a second position where the first nozzle sucks the reaction solution in the reaction vessel or the one of the reagents in the one of the reagent vessels.
