Abstract
A method to determine performance of a treating agent (CA) added to a system body of liquid to enhance performance of the liquid body is determined by employing an inert fluorescent tracer (T) in a known T:CA dosage proportion, prepared on the basis of a concentration of CA (e.g. ppm) proposed for optimum performance in the liquid body. The system liquid is sampled and, on the basis of fluorescent emission, the sampled indicator is compared to a standard ppm concentration of T to determine the concentration and efficacy of CA and the physical characteristics and operating parameters of the liquid body.
