ABSTRACT:
An electrolyte in a sample is stably measured by using an automatic biochemical analyzing apparatus wherein a flame photometer is assembled, which comprises a sample pipetting and delivering member, a reagent liquid delivering member, reaction cups charging the sample delivered through the sample pipetting and delivering member and the reagent liquid delivered through the reagent delivering member and a flame photometer for measuring an electrolyte, the method being characterized in that with respect to a sample cup to which the measurement of electrolyte is ordered, the sample pipetting and delivering member and the reagent delivering member are operated to deliver the sample and the reagent liquid to a reaction cup and an electrolyte of the diluted sample in the reaction cup is measured by the flame photometer and with respect to a sample cup to which the measurement of electrolyte is not ordered, the sample pipetting and delivering member is not operated and into a reaction cup corresponding to said sample cup is delivered a liquid from a liquid delivering member and this liquid is fed into a flame photometer and automatically measured to prevent the elevation of the temperature at the flame photometer. The liquid delivered into the reaction cup may be the said reagent liquid or a liquid different from the said reagent liquid. The calibration of the measurement is made in a specific embodiment for carrying out the above mentioned method.
