ANALYZER, AND METHOD OF DETECTION LIQUID LEVEL IN AN ANALYZER

摘要

Disclosed is an analyzer comprising: a container holder configured to hold a container containing a liquid; an aspirating tube configured to aspirate the liquid from the container held by the container holder; a drive part configured to transfer the aspirating tube; a detector configured to output a signal based on a physical characteristic between the aspirating tube and a liquid surface of the liquid in the container; and a memory configured to store, as a reference signal, the signal output from the detector when the aspirating tube is being transferred under a condition that the container containing the liquid which can be aspirated by the aspirating tube is not being held by the container holder; and a controller configured to detect the liquid level position of the liquid in the container, based on the reference signal and a real signal that the detector outputs, when the aspirating tube is transferred for an aspiration operation of the liquid.
