Abstract: Disclosed are methods that can be used to automatically calibrate a fluorescence-measuring instrument capable of continuously measuring the concentration of hardness in process water. The calibration method is used to compensate for drift of instrument and equipment, changes of operational conditions, and contamination of reagents and calibration standards. Calibration of the fluorescence-measuring instrument using the present calibration method improves both accuracy and repeatability for subsequent hardness concentration measurements.
