Abstract
Methods and systems for detecting and quantifying film forming amines in water systems are described. Water containing a film forming amine is combined with a fluorescent dye, the pH of the water is reduced, and then the fluorescence signal of the fluorescent dye is measured. The fluorescence signal is indicative of the amount of film forming amine in the water, and can be used to quantify the amount of film forming amine and control the amount of film forming amine that is introduced into the water system.
