摘要： Provided is an electrolyte measuring structure that can reduce the influence of the retention of a sample solution on a measured value, perform accurate measurement, and smoothly perform replacement work of an ion-selective electrode.
The electrolyte measuring structure that can be connected to another electrolyte measuring structure via a sealing material, includes a main body 401 having a flow path 401a therethrough, a fixing structure 404 having a fixing recess for fixing a sealing material 405 to the main body 401, and the sealing material 405. The sealing material 405 is an elastic body in which a sheet region and a protrusion region to be fixed to the fixing structure are integrally molded. In a state where the sealing material 405 is fixed to the fixing structure 404 and is not in contact with the other electrolyte measuring structure, a protrusion amount of a first portion that protrudes the most on a front surface of the sheet region is larger than a protrusion amount of a second portion that protrudes the most on a front surface of the protrusion region.-

摘要： There is provided an electrolyte analyzer that can appropriately replace consumable items while more exerting analysis processing performances than a conventional electrolyte analyzer does. An electrolyte analyzer includes a plurality of analysis chambers 50 having ISE electrodes 1 configured to measure the concentration of the electrolyte of a sample and a controller 29 configured to control operations in the electrolyte analyzer 100 including the analysis chambers 50. The ISE electrodes 1 of the plurality of analysis chambers 50 analyze the same analysis items. The controller 29 selects an analysis chamber 50 used for measurement from the plurality of analysis chambers 50 corresponding to the remaining measurable numbers of a plurality of ISE electrodes 1 and measurement request status.

摘要： An automatic analyzer is capable of normally maintaining a device condition and exhibiting a stable performance by automatically monitoring a cleaning implementation situation using a wash rack. The automatic analyzer includes an analysis unit, a rack loading unit into which at least a sample rack that holds the sample and a wash rack that holds a cleaning liquid are loaded. A transportation mechanism transports the sample rack and the wash rack to the analysis unit. A management control unit causes the wash rack to be transported to an analysis unit, causes a cleaning operation of the analysis unit by the cleaning liquid held by the wash rack, and causes stopping of the sample analysis operation of the analysis unit to which the wash rack has been transported until a performance of the analysis unit is determined to be normal based on the cleaning operation.

摘要： Provided is a technique for efficiently mixing a plurality of liquids by using only a single liquid feeding device. This liquid mixer comprises: a first inflow flow path into which a first liquid flows; a second inflow flow path into which a second liquid flows; a liquid merging part where the first liquid and the second liquid merge; an outflow flow path which is connected to the liquid merging part and through which the first liquid and the second liquid flow out; and a single liquid feeding device. The liquid merging part has a first flow path connected to the first inflow flow path, and a second flow path connected to the second inflow flow path, the first flow path branches into at least two flow paths, and the second flow path branches into at least two flow paths. One among the flow paths branched from the first flow path and one among the flow paths branched from the second flow path are connected and merged with each other. Another one of the flow paths branched from the first flow path and another one among the flow paths branched from the second flow path are connected and merged with each other on the downstream side, and are connected to the outflow flow path.

摘要： An analysis device measures ion concentration in a sample to detect an abnormality using an ion selective electrode. The analysis device includes an ion selective electrode that obtains a potential based on the ion concentration, a reference electrode that obtains a potential based on a reference liquid, a measurement unit that measures an electromotive force between the ion selective electrode and the reference electrode, an analyzer that analyzes a potential change of the electromotive force in a certain time region, and a storage that stores abnormality analysis data indicating a relation between the potential change and an abnormality of the analysis device. The analyzer acquires a parameter for the potential change of the electromotive force measured by the measurement unit, and analyzes the abnormality of the analysis device based on the parameter and the abnormality analysis data stored in the storage.
