摘要： 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.

摘要： Methods of and systems for treating a web of chopped nonwoven mineral fibers passing through a chopped nonwoven mineral fiber mat process are provided. The methods comprise spraying strength aid onto the web of chopped nonwoven mineral fibers in a forming section of the chopped nonwoven mineral fiber mat process. The systems comprise a first spray bar comprising a delivery conduit configured to provide a flow of strength aid at a flow rate to one or more nozzles in fluid communication with the delivery conduit. The one or more nozzles are configured to receive the strength aid from the delivery conduit and to spray of the strength aid onto the web of chopped nonwoven mineral fibers in the forming section of the chopped nonwoven mineral fiber mat process.

摘要： Provided are automated methods for measuring soluble magnesium concentration in water using fluorescence. The methods employ the use of a pH-buffered liquid and a magnesium coordinating fluorescing reagent. In certain embodiments, the methods may further employ measuring total hardness concentration of the water by displacing any soluble calcium with soluble magnesium and then re-measuring the soluble magnesium concentration. Optionally, the soluble calcium concentration can be determined by subtracting the measured soluble magnesium concentration from the measured total hardness concentration.
