Herewith disclosed is a sample analyzer comprising: a measurement section configured to perform a measurement on a sample and generate a measurement value according to the concentration of an analyte in the sample; a memory storing a calibration curve; an analysis section; an output section; and an instruction receiver. When the instruction receiver receives an instruction to perform a diluting measurement on a calibration sample, the measurement section dilutes the calibration sample by a predetermined ratio and performs a measurement on the diluted calibration sample, and the analysis section determines the concentration of the analyte in the diluted calibration sample by applying a measurement value obtained from the diluted calibration sample to the calibration curve. Information generated based on the determined concentration and the known concentration is output.

Sample analyzer and a sample analyzing method

A sample analyzer comprises a pipette, a pipette moving mechanism and a position confirming member disposed at a position where the pipette can be moved by the pipette moving mechanism. The position confirming member comprises a space into which a tip end of the pipette can be inserted. When the sample analyzer carries out the position confirmation process, the tip end of the pipette is moved by the pipette moving mechanism so as to be inserted into the space of the position confirming member. When a sensor sensed that the tip end of the pipette collides with the position confirming member, the sample analyzer stops the movement of the pipette and notify that the pipette of the pipette moving mechanism has a problem.

Sample analyzer and a computer program product

An analyzer comprises a dispenser which dispenses a liquid into a container, a detector which comprises a phototransmitter which emits light to the container and a photoreceiver which receives light from the phototransmitter, a moving unit which changes a relative position between the container and the detector, and a controller which determines whether an amount of the liquid in the container is within a predetermined range, based on outputs from the detector at a plurality of the relative positions.

Analyzer, method for determining a dispensed liquid amount, and non-transitory computer readable medium

Specimen analyzer includes a first holding section for holding a container; a first mechanism section for executing a first operation for the container on the first holding section; a second holding section for holding the container; a first transfer mechanism section for transferring the container from the first holding section to the second one; a second mechanism section for executing a second operation for the container on the second one; an error detector for detecting error in the first mechanism section; and an error controller for controlling the operation of the first holding section, the first and second operation so that the first operation and the transfer operation of the first holding section would be stopped while the second operation would be continued in case of the error in the first mechanism section. An abnormality control method of the analyzer and computer program product are also disclosed.

Specimen analyzer, abnormality control method of the same and computer program product

The present invention is to present a liquid dispensing apparatus which is capable of preventing contamination by previously aspirated liquid, even when residual liquid in a pipette tip separated from the dispensing apparatus is scattered. The liquid dispensing apparatus includes: sample dispensing armwhich comprises a dispensing nozzlefor aspirating and discharging sample on which a pipette tipis attached; tip separating sectionfor separating the pipette tipfrom the dispensing nozzle; and nozzle wiping sectionfor cleaning a tip of the dispensing nozzle
