Abstract
Provided is an electrolyte analysis device capable of suppressing a burden with respect to measurement while suppressing a decrease in accuracy of a measurement result. An electrolyte analysis devicethat measures a concentration of a specific ion in a sample using a plurality of ion selective electrodes of an ion selective electrode group, and a reference electrodeincludes a water supply tankconfigured to store system water used for at least one of solution sending, probe cleaning, and temperature adjustment in the electrolyte analysis device, a specimen dispensing deviceconfigured to dispense a sample to be measured, a dilution tankconfigured to dilute the sample dispensed by the specimen dispensing devicewith the system water, a water quality measurement unitconfigured to measure the ion concentration of the system water in the water supply tank, and a control deviceconfigured to control the electrolyte analysis device, in which the control deviceperforms water quality determination processing of determining whether a water quality of the system water is normal or abnormal based on a measurement result of the water quality measurement unit
