A MANAGAEMENT SYSTEM FOR AN ELECTROLYTE ANALYZER

Electrolyte analyzers are used in a variety of ways, and problems vary from reagent deterioration due to reagent replenishment, mixing of foreign substances during reagent replenishment, electrode deterioration due to the passage of the validity date, to the operator's inputting errors. It is thus necessary to judge abnormalities of measured values resulting from such inappropriate usage, based on the fluctuation patterns of the results of daily electrolyte calibration. The invention provides a comprehensive method of precision control. The method includes the steps of: extracting the fluctuation patterns of each measured item from the results of daily electrolyte calibration; calculating the electromotive force balance ratio between the internal standard solution and high/low-concentration standard solutions as well as its fluctuation pattern; comparing all the obtained fluctuation patterns against atypical fluctuation patterns stored on the electrolyte analyzer; examining the deterioration of the electrodes and electrolyte reagents and errors in inputting the concentrations of the standard solutions; and activating an alarm.
