Abstract:
1. An automatic analyzer comprising: a reaction vessel in which an analyte is caused to react with a reagent; a probe for suctioning the reacted analyte from the reaction vessel; an analyzer unit for analyzing the reacted analyte; a transfer channel for transferring the reacted analyte suctioned by the probe to the analyzer unit; a liquid surface detector, connected to the probe and the reaction vessel via a signal line, for detecting electrical characteristics between the reaction vessel and the probe; a physical switch disposed on the signal line connecting the liquid surface detector to the probe to prevent electrical fluctuations that arise from the liquid surface detector from reaching the analyzer unit; and a processor programmed to open the physical switch to prevent electrical fluctuations arising from the liquid surface detector from reaching the analyzer unit while the analyzer unit is analyzing the reacted analyte.
