1. An electrolyte analysis apparatus comprising:
a high-concentration reagent bottle configured to store a high-concentration reagent;
a reagent diluent bottle configured to store a reagent diluent for diluting the high-concentration reagent;
a first flow path configured to send the high-concentration reagent from the high-concentration reagent bottle;
a second flow path configured to send the reagent diluent from the reagent diluent bottle;
a junction unit configured to join the first flow path and the second flow path;
a third flow path configured to send a prepared reagent which is a mixed liquid of the high-concentration reagent and the reagent diluent from the junction unit;
a dilution tank configured to store the prepared reagent;
a prepared reagent discharge nozzle configured to discharge the prepared reagent sent in the third flow path to the dilution tank;
a liquid sending mechanism configured to send the high-concentration reagent and the reagent diluent to the junction unit at a predetermined ratio so that the prepared reagent discharged from the prepared reagent discharge nozzle to the dilution tank through the third flow path has a predetermined concentration, wherein the third flow path has a winding structure wound in a spiral shape with a predetermined radius; and
an analysis unit configured to perform analysis with the prepared reagent stored in the dilution tank, wherein
the liquid sending mechanism alternately sends the high-concentration reagent and the reagent diluent to the junction unit.
