9. A method of automatic analysis of a specimen using an automatic analysis device that includes an electrolyte measurement unit, the method comprising:
executing, by the electrolyte measurement unit, a measurement operation, in a predetermined cycle, of measuring an internal standard solution measurement once or more at least before a potential measurement of a second specimen, and
wherein the potential measurement of the second specimen is continuously executed by the electrolyte measurement unit, and upon determining there is a possibility that a first specimen measured immediately before the second specimen is a high concentration specimen based on a comparison of a first ion concentration measurement range of the first specimen and a second ion concentration measurement range of the second specimen, the measurement operation of the internal standard solution before the potential measurement of the second specimen is changed without changing a duration of the predetermined cycle.
