Fluid analyzer for magnesium ion measurement and calibration method of potentiometric magnesium ion sensor in the same

摘要

A fluid analyzer for analyzing a fluid sample containing one or more analytes and a method for calibrating it. The fluid analyzer controls at least one automatic valve to pass at least three calibration reagents through the fluid flow path to the secondary ion selective electrode, the primary ion selective electrode and the reference electrode, and the signal generated by the meter Determining calibration information using calibration logic obtained from and controlling the at least one automatic valve to selectively select different subsets of the at least three calibration reagents to the secondary ion selective electrode, the primary ion selective electrode And a control system for determining recalibration information using at least one of the signal generated by a meter and the calibration information and recalibration logic, and through the fluid flow path to a reference electrode To do.
